An example of sag on a vehicle's rear axle under a heavy load

Whether you're hauling heavy loads in your bed or cargo area or you're towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits, 1" above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's side or passenger's side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you are hauling off-center loads.


An example of a trailers swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer, and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi), because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Great product. I haven't installed this set on my new truck yet, but I had them on my older truck and they did the job they were intended to do. Only problem was when the package arrived, the box was split open to the point of everything falling out. But no parts were lost, this time.



by:

This is a excellent product. I had them in my F-250 and when I bought my new RAM it was the first accessory I added. Best bang for the buck suspension product on the market today!



by:

Definitely worked as advertised, very easy to install.



by:

The service and delivery of these suspension assist was an example of professionalism. I am grateful.



by:

Canot believes that it came from so far and did not even take 2 full days to cross the border all the way to a small town in the province of Quebec Canada 2 tums up for deleverer for the timbren product took 30 minutes to complete the job very easy took the pick up for a ride this morning did not see any difference in handling the truck was empty can't wait to see how good of a job they will do when pulling the fifth wheel next week thanks again



by:

They did not fit right on my 2021 power wagon, I had to modify to make them line up with my differential and had to buy shorter mounting bolts for the bracket plus they where already used



by:

Very easy to install 30 min. tops. Have not tried them with the trailer yet but I'm sure they will do the trick. Very pleased!



by:

These work. Smoothed out the ride on my Xterra very nicely.



by:

Easy install. Product arrived before delivery date. Can already feel difference when just driving. Will hook up camper in a few week to see the real results.



by:

Product worked as described. Very easy installation for one person.



by:

They look as shown on the home page
Fast service



by:

Look alot beefier than stock... can't wait to put them in. It'll be a few more days. My trailer is still hooked up to the truck.



by:

15 minute install. Works as described. Easier and less expensive than helper springs



by:

Great servive and delevery very fast. And the video of installation on the site web was appreciated, they helped me , i watch them install my product in a time record.



by:

Just installed today, Took the spacer off after test drive. A lot smother ride than the airbags that I took off for these.



by:

Works great for heavy tongue weight conditions! But etrailer, c'mon man, you can't ship this in a retail box!!! USPS received the damaged box from UPS, and they had to tape it up for final mile delivery. Luckily everything was still in the box.



by:

Ordered Timbren SES for 2017 F350 4x4. Hope to reduce sway when loaded with truck camper. Arrived in less than 48 hours. Installed easily. Will road test in a couple weeks.



by:

Work as advertised. Truck only drops 1" . Easier & less expensive than air bags

by:

I have a 2020 Ram 1500 Classic. They were easy to install once I used soap, not soapy water. I tried the soapy water and could not get them in. Used straight up Dawn and they went right in.



by:

My husband attached them to his truck and my husband stated that they were extremely easy to install, directions were very simply and easy to follow. Shipping was extremely fast and efficient and arrived right on time. We haven't attached our RV to our truck and haven't taken our camping trip yet. So we can't give a review about how well the truck will handle once a load is attached.



by:

Third truck I’ve used Timbren’s on, they are great. No more broken leaf srings. Quick shipping. You won’t regret this purchase.



by:

BIG difference in handling a load or trailer ... what a great product!!!



by:

Helped to level my truck out when pulling my 5th wheel

  • Recommended Suspension Helper Springs for 2021 Chevy Tahoe Towing Large Aluminum Boat
    Since you're towing a consistent load, I'd recommend a jounce bumper replacement-type system versus an air helper spring. Such a system won't affect your ride quality unless the rear suspension of your Tahoe is compressed from hauling cargo or the tongue weight of a trailer. I'd recommend the Sumo Springs # SSR-204-40 which will provide up to 1000 lbs of additional support. The way a jounce bumper spring replacement works is that they won't have any influence on the ride of the vehicle...

  • Recommended Suspension Enhancement For A 2005 GMC Yukon XL Denali
    Hi Arman, The Timbren Rear Suspension Enhancement System # TGMRYS4 are rated for 6,000lbs so they'll definitely help with the sagging, but being as high capacity as they are they'll likely also affect your unloaded ride quality in a negative way. Going with a lower capacity like the SumoSprings Solo Custom Helper Springs # SSR-204-40 (1,000lb load leveling capacity) would help with the sagging without giving you a harsh unloaded ride quality. These springs are a simple swap out of the...

    Since you have the auto leveling suspension on your 2008 GMC Yukon XL you'll need suspension enhancement that replaces the bump stop of your suspenion like the Timbren kit part # TGMRYS4 for if you have a 1500 or the part # TGMRSB4S for if you have a 2500.

    The two Timbren rear-axle suspension enhancement kits you referenced, part # TGMRYS4 and part # TGMRG25C, are both fits for the 2002 Chevrolet Tahoe, but kit # TGMRYS4 fits the 2-wheel-drive version while kit # TGMRG25C fits the 4-wheel. Both kits fit vehicles that do not have the Police Package and both install without drilling using included hardware. Both offer 6000-lbs of load support. Installation videos for both kits are linked for your reference.

  • Recommended Timbrens for a 2002 GMC Yukon XL 1500
    Hey Galen! In order to determine if you need spacers, what size, and how many, you will need to take a couple of measurements. The Timbren Rear Suspension Enhancement System item # TGMRYS4 measures 4-3/4" tall including the puck portion that fits into the cup on the frame. You're going to want 1/2" to 1-1/2" above the axle so that your unloaded ride quality is not changed. The Timbren Front Suspension Enhancement System item # TGMFK15A are 3-9/16" tall, but this kit also includes a 1"...

  • Is The Spacer Kit # T68MR Compatible With Timbren Springs # TGMRYS4?
    While the spacers included in the Kit # T68MR will work with your Timbren Springs # TGMRYS4 they do not use the same mounting bolts. Your GMC Yukon uses 3/8" hardware while the spacer kit includes M10 hardware so you would still need to source the longer bolts in your 3/8" thread size.

  • Recommended Suspension Enhancement System for 2004 Chevrolet Suburban
    For your 2004 Chevy Suburban, the Timbren Rear Suspension Enhancement System for 4x4 # TGMRG25C will give you load stability and support to help reduce sag. It also will help reduce body roll and will assist your vehicle suspension with absorbing shock. It will not turn your Suburban into a truck, but it will help it to drive and operate more similar to one. If you have a 2wd Suburban then you will want # TGMRYS4 instead which offers the same features but is a fit for 2wd vehicles.

  • Recommendation on a Rear Suspension Enhancement for a 2011 Chevrolet Avalanche
    For your 2011 Chevrolet Avalanche. I recommend the Timbren Rear Suspension Enhancement System, # TGMRYS4. The Timbren system will sit above the rear axle of your Avalanche and help stabilize and level your vehicle when under a towing load or hauling in your vehicle's bed. The Aeon springs become more rigid as more weight is added allowing your Avalanche's body to ride at a more level position. Note: Using a suspension enhancement system like the Timbren system will not increase your vehicle's...

  • Weight Distribution and Suspension for 600 lbs Tongue Weight Trailer and 2001 Chevrolet Suburban
    With a 600 lbs tongue weight on your travel trailer, I recommend the # FA92-00-0800 Fastway e2 Weight Distribution w/ 2-Point Sway Control. This system is for a tongue weight of 400-800 lbs. Since you are at 600 lbs that puts your tongue weight right in the middle of the range which is ideal when using weight distribution. This has a bolt on installation so no drilling is required. As for heavy duty shocks and adding a leaf to your leaf springs, we do not carry shocks or an add-a-leaf...

  • Can Air Bags and Rubber Helper Springs Be Installed Together on a 2005 GMC Yukon XL
    The stock bump stops on your 2005 GMC Yukon XL should be located outside of the coil springs so they would not interfere with the AirLift system you installed. You could add some different rubber springs such as # TGMRYS4 but since you already have the air bags installed you would not need to upgrade the bump stops. If they are in bad shape you could get some replacements either from a GM dealer or inquire at a local auto parts store. Or if you want bigger ones you could install the Timbren...

  • What are the Dimensions of the Timbren Spring # TGMRYS4
    I spoke with my contact over at Timbren about helper springs # TGMRYS4. The overall height of the whole assembly is 4-3/4 inches. The spring by itself is 3-3/4 inches. You'll want an inch to an inch and a half of space between the frame/axle and the Timbren to ensure you ride quality isn't too harsh.

  • Difficulty Installing Timbren Helper Springs on a 2005 Chevy Suburban
    Timbren springs # TGMRYS4 are a very tight fit, they have to be, so I can understand the trouble you are having. First, remove the springs and make sure to clear out in debris or corrosion where the springs install. You can use soapy water to help the springs slide into place but it is going to take some pressure. You may need to seat them as best as you can and then possibly place some wood blocks directly below the springs and slowly lower the vehicle so that the weight of the vehicle...

  • Timbren Springs Not Lining Up with Axle Bracket on 2004 GMC Yukon XL
    Is it the additional spacers that are causing the main part of the spring to out of alignment compared to the stock bump stops on your 2004 GMC Yukon XL? Are the Timbren springs fully seated in the bump stop cups? On these vehicles it is hard to manually push them into place. We usually use a block of wood and slowly put weight back on the axle so that the wood and the weight will push the springs into the bump stop cup. And I know you have the Z71 springs but is the Yukon itself 4-wheel...

  • How to Reduce Sway of Towable Ice Fishing Shack Towed By 2011 GMY Yukon XL
    Typically, the best way to combat trailer sway is by using a weight distribution system with an integrated sway control component but from what I saw online, your fish house has a very unique trailer tongue that wouldn't be well suited for a weight distribution system. The Timbren # TGMRYS4 helper springs would help somewhat with sway, but not to a huge degree. I'd replace the factory anti-sway bar with a larger one such as the Roadmaster # RM-1109-168. A larger diameter anti-sway bar...

    For your 2013 Chevy Suburban 1500 with 4-wheel drive, between the Air Lift AirLift 1000 Air Helper Springs # AL60769 and Timbren Rear Suspension Enhancement System # TGMRYS4 I highly recommend going with the Timbrens. The coil springs will not give you the amount of support the Timbrens do, and the Timbrens have another huge advantage in being maintenance-free. Once you install the Timbrens you don't have to worry about them again, while the Air Lift springs are going to require consistent...
