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.

2014 Ram 3500

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.


Comments
One year and I still think these are a great product. They work very well with the weight of the camper and improve sway control as well as squat. Well worth the investment.

Here are some pics of my installed Torklift Stableloads after drilling through my springs on a 2020 F250. I had to loosen and shift my exhaust pipe to drill the hole in that spring. Applied pressure to my drill with a floor-jack and went with low RPM on the supplied drill bits. I am very happy with etrailer’s quick shipping and the Torklift Stableload product worked as advertised




by:

Product does give us a reduction in sway. Doesn't get it all, tho. Have added various other SES products to help out the stableloads. With these additions I am satisfied

Chevrolet SS

I have used these on my last truck for 5 years. Great asset with my truck camper. These new SS Stable Loads will be even better especially since I live in the north east, better known as the rust belt/




by:

Great product




by:

Nite and Day difference for having our slide in camper loaded up. Even with air bags and a aftermarket sway bar, I felt I needed “something” more at the back of the vehicle. I didn’t want stiffer springs because my load doesn’t actually tax my stock springs. The load is just tall. Utilizing the overload springs with this TorkLift kit did the trick. Only thing I did different was add a rubber o-ring to the base of the head on the latch-pin to stop the rattling of said pin when on bumpy broken California roads.

I’ve to have stainless! Stable load makes hauling the camper much more steady.

2014 Dodge Ram Pickup

When I first got this rig(2014 RAM 3500 DRW carrying a Lance 992 4K pounds), it already had the upper stable loads and I still experienced porpoising, sag and sway. Then at the end of last season I notice we were listing to one side. It turns out the upper stable loads had disintegrated. I had to buy new ones because the lifetime warranty is non transferable. So While looking into that I saw the lower stable loads and decided to get those too.

After I first installed the stable loads(along with the new upper stable loads) I took the rig for a test drive and I could tell immediately there was improvement with handling as could my wife. But I was a little skeptical, thinking I was just being overly optimistic. So I decided to wait until I had a more thorough test before writing a review.


We've been boondocking in the Southwest for the last three weeks(geographic distancing) and have been driving on a lot of bumpy roads and a lot of washboard roads, interstate and state highways, you name it. I think I've hit all the road conditions that have caused us problems in the past.

Problems I used to have that I haven't had an issue with yet:

Porpoising --- This is very surprising and fantastic. We experienced porpoising at least once during every extended drive. I'm pretty shocked that I haven't had it happen in three weeks. I really hated porpoising.

Sag - People would flash their lights at me at night because the sag caused the front to tip up enough to make it appear as though my brights were on. This is not happening any more.

Sway - We used to experience a lot of sway and this has disappeared as well. Maybe if I drive like a maniac I'll get some sway, but I'm not going to risk it.

It's such a comfortable ride now and I'm genuinely surprised. It seems like a cheap and easy fix and I don't understand why truck manufacturers don't offer this for their vehicles.




by:

Using this on an F350 w/ a Truck camper towing a 16 foot toy hauler. It's reduced the rear sag of the truck and provided better handling characteristics on the road. Good alternative to airbags.

The installation holes were made using the provided drill bits and a hydraulic jack to load the drill. Not too bad from a time stand point. Perhaps their provided drill jig may be easier or faster?

Some of the components had fit issues due to burrs that weren't cleaned up after machining. A quick hand deburr took care of that issue.

Overall a good product; despite the few minor fit issues. Installation instruction were clear as well.




by:

Install went well. Performance as predicted. No five star rating because the fasteners
are not stainless steel and are already rusting.




by:
2006 Ford F-250 Super Duty

This is so simple and so effective. It nearly completely eliminated camper sway on my 2006 F-250. The stainless version should last forever.

Review from a similar StableLoad in Vehicle Suspension


Well overall I gave them a 4 rating. Great website complete with installation pictures and video. Shipping and messages regarding orders are always updated daily. The only negative are the tabs on the upper Stableloads tabs are machined wider than the factory bump stops requiring me to press them closer together so that they would pop into place. Thanks for allowing me the opportunity to again do feedback on this product.


Comments
After a year they are still doing what they are supposed to do and that is engage the upper overload springs sooner than the factory bump stops allowing the truck to maintain level. Hold up well even in salt and sanded roadways during northern tier winter travels.

Review from a similar StableLoad in Vehicle Suspension


I purchased 6/1/22 received 6/7/22 and I’ll give 5 stars for simple and easy installation. Took all of 10-15 minutes to install all 4 pieces including removing OEM stoppers. Only reason for purchasing these is that I purchased the Air Lift 5000 Air springs assist and the Air lift Smartair II DuelCompressor for Ford F-250 2020.
The Smart Air II with Leveling arms has been a nightmare and have had to replace now 2 airbags same side that failed and a compressor that has now failed and quit working. Hopefully these will prevent in the event of an airbag failure from allowing the airbag to drop completely and damaging my truck again with a leveler arm going thru my truck. Will see how new airbags and new compressor system works with these torklift and will put my travel Trailer on and hopefully the torklift will stop the arms from hitting the truck bed.

Review from a similar StableLoad in Vehicle Suspension


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.


Comments
The wedges do level the truck when loaded up and towing the trailer. The truck must be jacked up to engage or release. They squeek & creek when engaged, but they do the job.

Review from a similar StableLoad in Vehicle Suspension


They work great. I did have to modify them to fit my 2017 F350 SRW, like others have mentioned in their reviews, the tabs don't fit. The tabs are too wide to fit in the slots on the truck. I ended up trimming my tabs, so that they still fit in the rubber peice and welded new tabs so that they fit in the slots on the truck. Doing this won't allow either piece to spin. I haul a truck camper and these took some weight off my timbrens and the truck is less tippy side to side. Would be 5 stars if they fit, without modding.

  • Recommended TorkLift StableLoad For 2020 Ram 3500 with Single Rear Wheel
    Yes. I double checked this with TorkLift and the TorkLift StableLoad Rear Suspension Upgrade w Quick-Disconnects - Lower Overload Springs - Universal # TLA7311. These are a universal fit part, so they're designed to fit on a wide variety of trucks, including your 3500 with the single rear wheel. These are also available in stainless steel with part # TLA7311S

  • Is Drilling Required to Install TorkLift StableLoad Suspension System on 2022 Ford F-250 Super Duty
    Yes, you will need to drill into the leaf springs on your 2022 Ford F-250 Super Duty whether you go with the standard TorkLift StableLoad # TLA7311 or the Stainless Steel version # TLA7311S. I checked with TorkLift and it looks like you'll need to drill 7/16" holes but specialty drill bits are included in either kit so that's one less thing you have to worry about picking up.

  • Why Does TorkLift StableLoad Suspension Upgade TLA7311S Include Four Units?
    You are correct that the description of the TorkLift StableLoad Suspension Upgrade w Quick-Disconnect # TLA7311S for your 2007 Ford F-250/350 include four units. This is because you need to install one on both the front and rear of each overload spring as that is what allows the spring to engage sooner while still giving even support. You are not able to purchase just two units as the kit will not work properly with just two. I included a video of the # TLA7311S for you to take a look at.

  • What Size Are The Mounting Bolts Included With The TorkLift StableLoad TLA7311S?
    The mounting bolts included with the TorkLift StableLoad # TLA7311S you were looking at are 7/16" in diameter so they will fit the .525" holes in the leaf springs of your 2007 Ford F-250. Since you already have the holes, you do not need to do any drilling to get the kit installed. I included an installation video of the # TLA7311S for you to take a look at.

  • What Size Drill Bit is Needed for TorkLift Stableload
    I spoke to TorkLift and the holes needed for the # TLA7310S will be 7/16". With leaf springs being a hardened steel, it is suggested that a harder drill bit is used. We do actually have # TLA7311S that would come with two 7/16" cobalt drill bits that would solve this issue.

    Yes, you can use the TorkLift StableLoad # TLA7310S on your 2021 Ford F-350 Tremor as long as you have a lower overload spring. If your overload springs already have the hole you will be able to bolt them directly to the spring. If you do not have the holes already in your overload springs you will need to drill four 7/16" holes to attach the StableLoad kit. The TorkLift StableLoad # TLA7311S includes the drill bit necessary for drilling these holes. For your F-350 having the Tremor package...
