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.

by:

Sorry to report that the Timbren package arrived in original box that looked as though it had been ripped open and the carefully taped shut with clear packing tape. I thought at first that shipper had damaged it but all parts were there so I started install. Half way thru I discovered two of the lock nuts were stripped and threads on the right axle pad were burred at the start. We live 14 miles round trip from the closest ace hardware. I used a die to repair the axle pad threads but had to stop for the day to purchase new lock nuts. Feel like I got a used set for new price.



by:

Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.



by:

Easy to install and does not affect the ride till you have a load, then they help support the load. Good product!



by:

Great Product, arrived quickly and packaged well.

Will be buying from them in the future.

  • Are There Air Bags for a 2002 Workhorse P42 Chassis
    I do have suspension enhancement options for a 2002 Workhorse P42 Chassis but there are no air bags available unfortunately. Instead, you can use the Timbren Rear Suspension Enhancement System. The correct one will be based off the suspension. The part # TGMRP30MH is for models with bump stop over u-bolt pad and part # TGMRP30 is for models with bump stop on the frame. These options all work well to provide additional support.

  • Timbren Rear Suspension Enhancement System for a Food Truck on a 2005 Workhorse P42 chassis

  • Softening the Ride of an RV on a 1988 GMC P30 Chassis
    Timbren springs do have the reputation for creating a stiffer ride. The best solution to soften up the ride is to use air bags. For the front axle on your 1988 GMC P30 chassis you can use # AL81560. For the rear use # AL57203 (Note: Designed for vehicles with a GVWR less than 14,500 lbs.) Then you could add a dual path compressor system, # AL25856, so you can adjust the air pressure from the comfort of the vehicle cab. A dual path would be needed since the front and rear air bags have...

  • How To Improve Ride Quality On 1984 Winnebago Chieftain
    The Timbren Front Suspension Enhancement System part # TGMFP30W which is a fit for a 1984 Winnebago Chieftain is mostly for support but can also be used to help produce a more comfortable ride by absorbing road shock and improving roll stability per Timbren. There is also a kit for the rear, the Timbren Rear Suspension Enhancement System part # TGMRP30.

  • Rear Suspension Kit that Fits 2007 Workhorse W42 Chassis
    For the Workhorse W42 chassis we have the Timbren rear suspension kit part # TGMRP30 but we don't have any air spring solutions. The Timbren kits offer the same support without requiring you to worry about air pressure and leaks though.

  • Rear Suspension Enhancement that Fits 2001 Workhorse W20 Chassis RV
    I checked with Air Lift and they confirmed that the kit only fits the 2002 and newer W20. We do have a Timbren kit part # TGMRP30 that fits your 2001 W20 which would give you the same support but has advantage of not requiring you to monitor air pressure.

  • Recommended Timbren Suspension Enhancement Kits For A 1994 Safari Trek On A Chevy P32 Chassis
    The Timbren Front Suspension Enhancement System # TUF100 you referenced is not a confirmed fit for your 1994 Safari Trek on a P32 Chassis. You would need the Timbren Front Suspension Enhancement System # TGMFP30W instead, which would be a direct replacement for the front bump stop and would not require drilling. If you want to install a rear axle kit as well you would need part # TGMRP30.
