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 when loaded. 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 when loaded or towing because the rubber has more travel.

Tried to order part first time, rotten customer service. Called back spoke to manager, much better service received part very quickly. Unfortunately part had bad bolts and or nuts, would not work together. Manager said if I had any problems I could call her number directly and she would take care of it. Have tried to reach her for three days no response. Called regular etrailer number and they want pictures sent to them and then it would have to be reviewed and I was informed I they were behind schedule, so only could guess how long it would take. Sending parts back and demanding refund. Have been doing business with etrailer for many years and this is the thanks I get for being a long time customer. Will not be shopping with etrailer ever again

  • Comparing Timbren Rear Axle Jounce Spring Suspension Kits TGMRYS4 and TGMRG25C
    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.

  • 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...

  • Adding Timbren Suspension Enhancement System On a 2019 Yukon With The Magneride Air Suspension
    Adding any after market bump stop/jounce bumper could potentially raise the vehicle 1" because they are longer than the factory bump stop however, they are compatible with the Magneride system. Adding them can potentially effect how the vehicle rides when not towing and how the vehicles built in sensors for the air springs read the level of the vehicle. There are two types of bump stops/jounce bumpers available for the 2019 GMC Yukon 6.2L with the Magneride system. The Timbren Rear Suspension...

  • Recommended Timbrens For A 2009 Chevy Express 1500 Van All Wheel Drive
    For the front of your 2009 Chevy Express 1500 I recommend getting the Timbren #TGMFK15A. This will the 2WD, 4WD, and AWD models. We also have the # TGMRG25C available for the rear if you are in need. These will be a very easy bolt on install and will go a long way to level your ride and absorb road shock when towing.

  • Highest Rated Suspension Enhancement Option For A 2003 Chevy Tahoe
    Hi Bob! The Timbren # TGMRG25C you ordered will have 6,000 pounds of load assist and will be the highest rated option available for your 2003 Tahoe. This will definitely solve your sagging issue, especially if you are close to or at the maximum load capacity of your vehicle. It must be pointed out, when you are unloaded your ride will be noticeably stiffer than your stock suspension due to their heavy duty nature. Personally, I prefer the Air Lift LoadLifter # AL60769 due to the adjustability....

    The answer to your question depends on the weight of your cargo and your expectation of comfort in your 2008 Chevy Express 1500 van. The Timbren Rear Suspension Enhancement System item # TGMRG25C has a capacity of 6,000 lbs but will provide a stiff ride. I typically only recommend these systems as a last resort or on work trucks with service beds. I recommend going with an airbag system like the Firestone Ride-Rite Air Helper Springs item # F2423.

  • Why Would Tow Vehicle Still Sag with Andersen Weight Distribution System being Used
    The Andersen weight distribution system isn't as effective as other systems. The reason you are still experiencing sag with a weight distribution system is solely because of how ineffective that system is. The chains they use instead of spring bars just doesn't work as well. Your best solution is going to be to go to a more effective system like the Reese kit part # RP66541 which will easily allow your Suburban to sit level. Suspension enhancement like the Coil Rite kit part # F4108 will...

  • AirLift Air Helper Springs Vs Timbren Enhancement System for a 2004 Cadillac Escalade
    The Timbren Rear Suspension Enhancement System part # TGMRG25C can be installed in conjunction with the AirLift 1000 Air Helper Springs for Coil Springs part # AL60769 but I do not recommend it. Installing both the Timbren's and AirlIft bags would create an extremely stiff suspension which would be rather bouncy and uncomfortable. Instead, I would stick with the AirLift bags as long as the tongue weight of your trailer does not exceed 1,000 lbs. If the tongue weight of your trailer does...

  • Cost Effective Suspension Enhancement System for a 2009 GMC Savana Van
    The most cost effective suspension enhancement system we have for a 2009 GMC Savana Van is the SumoSprings Solo Custom Helper Springs part # SSR-204-40 for 1500 models or part # SSR-205-47 for 2500 and 3500 models. These two options are more cost effective than the Timbren Rear Suspension Enhancement System part # TGMRG25C but they will also not provide as much support although will still work to reduce sag/squat.

If you're wanting the suspension product to counteract sag experienced when a trailer is hitched, you'd be better served by using a weight distribution system.

  • Suspension Enhancement Recommendation For 2014 Chevrolet Express Van
    To provide more support in your 2014 Chevrolet Express Van, I recommend the Timbren Vehicle Suspension, part # TGMRG25C. This will not affect the ride of your Express when empty but will help support the suspension when a load is added. The hollow rubber springs act like shock absorbers, and increase stability, along with extending the life of your suspension. This is a simple installation and replaces the axle bump stops on the frame. This system does not increase the weight carrying...

  • Ideal Solution for Stopping Rear Suspension Sag While Towing with a 2005 GMC Yukon XL
    I have a solution for you, but it's not suspension enhancement for your 2005 GMC Yukon XL. Instead I would recommend a weight distribution system as not only does it help with sagging, but since it reduces the sag by redistributing some of the tongue weight up to the front axle of the trailer you also get increased handling and braking performance. The part # TGMRG25C is a fit though and would give you rear suspension support. The best way to pick out a weight distribution system is to...

    The first thing you will want to do is inspect your suspension system to make sure it is in good working order.

The Timbrens are intended to help with a properly working system to help add support when carrying heavy loads. I called my contact at Timbren and they told me that adding additional support to the rear coil springs on your Tahoe like part # CSS-1094R will...

    In terms of capacity, the Timbren Rear Suspension Enhancement System, # TGMRG25C, for a 2003 Chevy Avalanche 1500 has quite a bit more; a total capacity of 6,000 pounds. Compare that to the maximum 1,000 pound capacity of the Firestone Vehicle Suspension, # F4108.

  • Weight Distribution for a 2004 GMC Yukon Denali XL and Trailer with 800 Pounds Tongue Weight
    I did some checking and your 2004 GMC Yukon XL Denali has a maximum gross trailer weight capacity of 8,000 pounds. This means that the maximum tongue weight capacity for the vehicle is 800 pounds. And this is assuming no passengers or cargo in the vehicle (which decreases the capacity). If at all possible I recommend reducing the tongue weight of the trailer by moving weight towards the back of the trailer. GM recommends the use of weight distribution on the trailer and not suspension...
