Enhancing Factory Overload Springs

The lower factory overload springs on your truck are designed to help compensate for a large payload. When you are hauling a heavy load, your truck's standard leaf springs can't always counteract the weight of it. As a result, if you hit a bump when your suspension is fully loaded, the leaf springs will give and cause your truck to bottom out. The overload springs help keep this from happening by mounting beneath the leaf springs to provide points of contact for the stressed springs.


Gap Between Standard Leaf Spring and Lower Overload Spring

There is natural gap between your truck's standard leaf springs and its lower overload springs. This gap allows the upper leaf springs to flex a bit before making contact with the overload springs, but having this gap creates a situation where bounce (or jounce) often occurs. StableLoads are designed to fill the gap between your standard springs and your overload springs. This pre-activates the overload springs, ensuring that they are engaged from the start instead of engaging only when your leaf springs make contact, at which point you've probably already felt the jarring.


StableLoad Suspension Enhancement and Aftermarket Air Bags

By enhancing your lower overload springs in the way described above, you will notice less sway and body roll. This is due to the pre-loading effect of the StableLoads, which helps to better distribute the weight of your payload over the entirety of your factory suspension. This is the primary difference between StableLoads and many air bag overload systems.


With air bag suspension enhancement, the load in your truck is being taken on by the air bags. Air bags are designed to level your truck, and they operate as intended when they're under a normal load. But if you are hauling or towing a particularly heavy load, this type of suspension enhancement can create some problems. In order to get the correct amount of leveling and to ensure that your suspension won't bottom out, you will likely have to fill the air bags to a very high psi. Doing this effectively removes the load from your factory suspension. As a result, your truck's suspension is no longer able to operate as it was designed. This can lead to handling issues, such as porpoising, sway, or body roll.


If you currently have this problem with your air bag system, you can add StableLoads to your suspension and get the best out of both products. StableLoads are effective on their own, but they've also been tested with aftermarket air bag suspension systems. The two enhancements work particularly well together if you have a heavy payload. By installing StableLoads between your lower overload springs and your standard leaf springs, you are already adding support to your suspension to help prevent bottoming out, which air bags work to prevent as well. As a result, you won't have to fill the bags nearly as full, which means that they won't take as much of the load off of your factory suspension, thus allowing your suspension to function as designed - only better.


Quick Disconnect

TorkLift Fortress Propane Tank Lock

These StableLoads can be quickly and easily engaged and disengaged. The quick-disconnect design allows you to pivot the wedge pack - the piece that sits between the springs - in and out of position with a standard ratchet and 3/8" extension (not included). As a result, you can get a stable load when you're weighted down and then return to your regular ride when you're done hauling.


Tested and Proven Winner

TorkLift's StableLoads were tested against vehicles with no suspension enhancement and vehicles with air bags that were inflated to 100 lbs; and the results are clear. By adding StableLoads to your suspension your vehicle will ride smoother, causing less wear and tear on your suspension and tires. The trucks that were tested were loaded with 2,800 lbs. The degree of movement was then recorded, using an inclinometer, when the trucks encountered the 3 most common types of handling problems: side-to-side sway, porpoising, and body roll.


Preventing Side-To-Side Sway

Side-to-side sway is triggered when your vehicle encounters uneven ground, such as a pot hole, and the suspension gives way when it cannot counteract the weight of the heavy load being carried. This creates a side-to-side bouncing motion. As you can see in the graph above, air bags provide an advantage over no suspension upgrades. But the StableLoads offer dramatic improvement over both the standard suspension and the air bag suspension.


Preventing Porpoising

Porpoising is the rising and falling action your vehicle makes when driving over an object like a speed bump. Having too much bounce can make you feel like you're riding in the back of a school bus. As you can see in the graph, there is virtually no difference in porpoising between trucks with standard suspension systems and those with air bags. Only the StableLoad offers improvement for this type of problem.


Preventing Body Roll

Body roll occurs when your heavy load transfers unevenly as you navigate a turn, causing one side of your vehicle to lean dramatically. In some cases this can lead to your truck's tires coming off of the ground and it could even cause your vehicle to roll over if it is too top heavy. Again, according to the graph above, air bags offer no help with this problem. It is only with the StableLoads that stability improves.

Video Transcript for TorkLift StableLoad Suspension Upgrade w Quick-Disconnect Feature Review

Hello, neighbors and friends, welcome back. I'm Steve with etrailer.com. Today we're taking a look together at the TorkLift StableLoad Suspension Upgrade with the Quick-Disconnect Lower Overload Springs, and these are stainless steel construction. Now these are a custom fit. Make sure you're using our website, etrailer.com. The top center of the page, you'll find what's called our fit guide.

Just simply enter your year, make, and model, possibly some bed length, cab style, those kind of things, and make sure you're getting the right part the very first time. Now, these will dramatically improve the handling of your vehicle by pre-activating your vehicle's factory lower overload springs. They do help and they will evenly distribute the weight, and that's gonna ensure that the truck stays level for better handling, that kind of stuff. It's gonna reduce side to side sway and body roll, those kind of things. And they have a nice angled structure to them and it's very rigid.

And the angle structure itself is gonna minimize that contact surface to give you more effective support. And these tapered wedges here, they're all three tapered there, they're gonna give you a better, they're gonna fit between the curve springs better than like your normal flat pads that are out there. Now they are adjustable. You can simply pull a pin here. Keep in mind, I've got all this loosely put together here just for demonstration purposes, but you would pull the pin out.

And then from there, you can simply select either one wedge, two wedges, or three wedges, depending on your specific needs and want for your application. And like I said, I got this kind of loose here, so it's not gonna let 'em all spin as free as I want, but that's the general idea. You can simply put these out of the way when you're not using 'em. Put the pin back in when you're going down the road like normal driving and then they're not gonna be activated. So it's really a simple 1, 2, 3 second kind of deal on each individual one, and then they're set up and ready to go.

Now the wedge pack, like I was just showing you, it's on a very nice hinge mechanism. So the StableLoad can be pivoted in or out for the engagement, and you simply just need a 3/8 inch ratchet extension and a ratchet. Those are not included. Those are required for activation. That way you can spin that nut that's on all of those to get them down into place a lot easier, 'cause again, it's just loosely put together right now just for demo. Now again, everything here is a nice stainless steel construction. It's all heavy-duty metal. It's gonna be protected from all the elements. It's gonna be ideal for any climate out there. From Alaska all the way to Hawaii, it's gonna work perfect. It is compatible with aftermarket airbag suspension upgrades. So if you've got an airbag kit, that kind of stuff. This again is a custom fit for your vehicle. Again, check our fit guide. You can honestly install these yourself, pretty simple. It's gonna come with a nice set of instructions. There's no drill required, whatsoever. And again, you're gonna get four kits here of the StableLoad and all the necessary hardware that you see before you. Everything's very, very simple to install. It is made in the U.S.A. and it has a very nice lifetime warranty as well. Well, folks, that's gonna do it for our look together today at this TorkLift StableLoad Suspension Upgrade with the Quick-Disconnect Lower Overload Springs. I'm Steve with etrailer.com. Thank you so much for your time. Have a good day.

Good quality part as usual from TorkLift. Part of it arrived not manufactured correctly but an easy quick call to Etrailer and they got me connected with TorkLift for a popper replacement. I have ordered many items from Etrailer and due to the exceptional customer They have earned my business.

Thank you for package tracking and very quick delivery! I also appreciate the videos provided on your website that help to better explain how the StableLoad system works on the lower overload leaf spring, and how the stack of plates should be setup with the bolts and washers, etc. Thank you!

For a future video idea for the StableLoad product: could you have an an overload spring removed from a vehicle (from a Ford F150 for example), and then show close ups of how the StableLoads should be attached? That would be very helpful for the customer to confirm they have them installed correctly. Just an idea....



by:

I don't really do reviews very often, but these things work extremely well, especially when you consider that they only take a few minutes to install and they are only blocks of rubber that are held in place by one bolt! I sprayed my factory stops down with WD-40 and pulled them out with some long needle-nose pliers wedged on both sides of the stop, between the frame and the rubber. I then glanced at the directions, figured out the stack-up I needed and installed them in less than 10 minutes! I'm not kidding! The best part is they work! They close the gap between the frame stops and the upper helper spring, engaging the spring right off the bat. I have an F350 dually with a Grey Wolf 840 that weighs 2400 ish pounds, and I haul a car trailer with a total weight of 6000 pounds behind that! These worked so well, I was amazed! These are the only suspension enhancement of this truck, too! You might need something more if you are hauling a very large camper or 5th wheel, but for me, this is all I am going to use!



by:

Didn’t like them at all, driving with no load if the road was rough they hit the overload stops and made the ride rougher, would not buy again



by:

Product appears to work well and provide additional "lift" as stated.
The product itself is extremely overpriced for what you get. $400+ for $40 worth of parts.
Instructions are good considering they are covering several different installation scenarios.
Won't know status of recommendation until after longer term use. Product should last a long time and serve its purpose. I am curious what a constant load on the overload springs will eventually do to the suspension.



by:

I purchased this item to use on my 1999 Chevrolet Silverdo 1500 which I suspect had spent most of it's life hauling a fifth wheel trailer all over America. The springs seemed weak so I first tried installing coil over shocks on the rear. These proved to be defective and instead of going that route again I found Stableload. The installation was simple and quick and I am happy with the results. I leave the Stableloads in full time because I find my truck to be much more stable with less roll on curves and corners. I believe I have much better control of my truck during my daily commute over a rough, twisty backroad.



by:

The front brackets did not fit my stock 2005 F3 15 the down rods for the anti-sway bar were too close to the leaves springs to allow clearance for these stable load additions. Customer Service told me that they have never seen this problem before, that is hard to believe with all of the F350s on the road. However, I was told that I could use the rear plates on their own.



by:

Adding the Tork Lift stable load suspension really helped my truck from sagging when I load up the in-bed camper. The ride is smooth and the truck handles very well. The installation was generally easy and the instructions were spot on. I highly recommend these if you want a stable ride and no sagging.



by:

One year and 15 miles later, the upper stable loads are holding up great. They have zero signs of wear. 2022 Cevy 3500 Dually



by:

This activates the overload spring by establishing contact reducing the possibility of a jolt by on sudden contact upon increasing load. It also increases the range of travel under load. Photo can be requested if necessary



by:

They don't fit on my truck 2023 2300 denali. I will be returning them. The picture is the back
Help or Spring The torque lifts are 2 and a 1/2 inches I only have 2 inches in the back inch and a 1/2 in the front



by:

Simple to install, only small issue was the groove for the factory slots were parallel with the leaf springs on my 2024 gmc 3500, so I had to try to hold the new stabil loads centered while tightening because they kept trying to slide to the end of the slot in the bracket.



by:

This product has met my needs, it is simple to use. I installed them on my F250 and I pull a 37' bumper pull RV. My only complaint is that sometimes when disengaging the Torklifts they can be wedged pretty tight, I use a pry bar to spread the springs to help with this.

My review is specific to the Stable Loads for my 2014 Ram 3500 SRW 4x4 Diesel Pickup truck. First, the package arrived a day ahead of the delivery schedule. Inventory of the kit showed it was complete and matched the list of contents included. The overall impression was that this is a very well made and manufactured system. The stainless steel option seems to be well worth the small added cost. The instructions from TorkLift are a little vague in places so here are a couple of pointers. First, I needed more spacer washers than were provided with the kit due to the thickness of the lower spring. I was short a total of 4 washers. It seems like this is a simple detail that others should have made TorkLift aware of. Surprisingly, I found no mention of this on-line or in videos. Another vague area is regarding the orientation of the bracket on the spring pack itself. on my truck, I needed to install the stable load to the inside - between the frame and the spring. I tried to install the rear stable load to the outside (tire side) but found that even with stock size tires, the clearance was too close for my comfort (less that 1 inch between the bracket and the tire sidewall. On my truck, there is a wiring harness along the bottom of the frame at the rear drivers side that had to be adjusted closer to the frame to provide clearance for the bracket. Otherwise, all 3 of the other mounting locations had adequate room for the inside mounting location. Also, for my truck, using two of the three wedges provided the right thickness for proper engagement. Another note is that for my Ram, I did not have to drill out the springs because the rubber pad is installed into a hole on the overload spring. The hole is slightly larger that the diameter of the mounting bolt. This did not seem to affect the installation but again, it seems a bushing of some sort would be a good addition to the kit. Installation time was a bit longer that what I have seen mentioned by others but still, a few hours and it was ready for a test drive.

With the stable loads engaged, the empty ride is a bit stiffer that stock but not objectionable. The real test will be with the 3000lb+ camper installed. That review will have to wait.

E Trailer was great to order from and had the best price I could find on-line. This is the 4th or 5th time I have ordered from E Trailer and have never been disappointed.



by:

UPS delivered with packaging intact.
L
& R Wedges are wrapped separately and labeled. Hardware was contained in a sealed bag. 2 pieces were damaged, easily replaced at the hardware store.
Instructions were reasonably clear, but there is room for improvement there.
Installation :
Installation was on a 2018 Chevy Colorado and straight forward. There is the option of installing the units inboard or outboard. Inboard installation on the Colorado would have resulted in insufficient clearance between the spare tire on the rear units, and the fuel tank on the front. Outboard installation resulted in minimal clearance with the mud flaps on the rear, and contact with the brake line and supporting bracket on the left front. Some backyard engineering with waterpump pliers was required to create adequate clearance.
Use:
Engaging the wedges is not possible with weight on the axle. The truck must be jacked up enough to unload the springs before rotating the wedges into position.
I haven't had a chance to load up the truck and hook up the trailer. I'll provide follow-up when I do.



by:

Fantastic. I found a local shop to install them on my 2017 Colorado Diesel for 2 hours of labor. The difference was amazing. Previously I felt my boat was going to push me off of the road. With the TorkLift installed I am much more relaxed. It seems my truck is more relaxed too because I saw a 2mpg increase while towing.

I didn't realize that to disengage them it would require me to jack up the truck, but they are not bothersome driving around town while engaged.

So glad I bought these. I feel like it saved me from purchasing a new truck.



by:

Having been in the auto/truck repair business for over 50 years, I thought this would be a good Idea so I tried it. I could have made my own but it would be a lot of cutting and drilling because it is so many pieces. I used it to add capacity so I could haul my camper that I purchased three states away and had to pick up. I used 2 of the 3 plates because there wasn’t enough room for three. It did very well like that but after I got back I added the 3rd plate figuring I could use the third one by just jacking the truck slightly before engaging. I thought all three woul be needed once the camper was full of water and gear.
I am enclosing a picture of how ti drill the springs with using the vehicles own drill press (screw jack) for changing tires.
I still need to test fully loaded and with all three plates in place.



by:

Adds additional stability in wind. Air bags improved the level and ride, however, the distance from the overload bumpers was increased back to the factory distance. Which means a lot more side to side rocking before the helper leaf springs engaged. The torklift blocks reduced this gap and allowed earlier engagement without affecting unloaded ride.



by:

Performing as designed. Reduced sway and porpoise. Tip from Etrailer staff: had to use a small crowbar to spread the leaf springs during installation.



by:

Installed the torklift stable load suspension kit on my Ford F-150. Was very easy to do following the instructions included or directly from the website. Once installed solved all of my suspensions sway by lifting the load and putting more weight on the front wheels. Immediately corrected the steering problems and distributed the load evenly so the truck was level. They are also very easy to engage or disengage from the leaf springs. No more airbags, or air shocks for me.
