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.

Today we're going to take a look at the Timbren Rear Axle Suspension Enhancement System. This is a custom fit part. It is designed to fit 2003 to 2014 Chevrolet Express and GMC Savannah 3500 Vans. Now on a custom fit part, I always like to recommend for you to go to our website use our fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now this part will improve suspension, handling, and safety on your vehicle, provides nice additional support as needed so you'll always have a nice smooth comfortable ride, allows the leaf spring ample movement while cushioning light loads. It does ride just as smoothly when you're not hauling a load. These do become more rigid as more weight is added for great performance when you're hauling a heavy load, which will increase stability and reduce vehicle sag.

These do work independently, side-to-side adjustment, helps compensate for any off-center loads, and it will reduce body roll when swerving and turning corners. These will act as shock absorbers taking the brunt of any bumps and rough roads, which will help extend the life of your vehicle's suspension. This part includes everything shown here on the table, the two Aeon hollow rubber springs, custom fit brackets, and the hardware for a nice simple installation. They do even give you detailed instructions on how to install it. These are designed to replace the axle bump stops on your frame so there's no drilling required. Specs on this, the load leveling capacity on this part is 6,000 pounds.

Now these Timbren springs will not increase your vehicle's weight carrying capacity so you do want to make sure do not exceed the manufacturer's recommended weight limit. That should do it for the review on the Timbren Rear Axle Suspension Enhancement system.

I actually found that airbags worked better for my truck and trailer. I ordered those from you as well. May I return the Timbrens for at least partial store credit?

by:

Easy installation. Good quality.



by:

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!

  • SumoSprings for a 2008 Chevy Express 3500 Utility Van
    Yes, we do have SuperSprings SumoSprings for your 2008 Chevy Express 3500 cargo van. If it is a 2-wheel drive model you can use # SSR-205-47. There are no SumoSpring options for 4x4 models. If you do have a 4x4 then you can use Timbren springs # TGMRG30PL as long as the factory bump stop bracket is curved. If the factory bump stop bracket is flat then you would use # TGMRG30LB.

  • Timbren Rear Suspension for 2006 Chevy Express Van
    It actually really depends on what type of bumpstops you have on your 2006 Chevy Express 3500. You can simply choose from the following: Van 3,600 lb Capacity - # TGMRG35 Motorhome 3,600 lb with 1-Bolt Bracket - # TGMRG30 Motorhome 6,000 lb with 1-Bolt Bracket - # TGMRG30LB Motorhome 6,000 lb with 2-Bolt Bracket - # TGMRG30PL The part # TUR350 that you mentioned is a universal kit which will fit but it isn't a custom fit like the other options so I recommend using one of the custom options...

  • Timbren Rear Axle Helper Springs for a 2012 Chevy Express Van 3500 Cutaway Chassis
    Timbren springs # TGMRG30PL fit the 2012 Chevy Express Van 3500 chassis like yours as long as the factory bump stop has a curved bracket. If the van chassis has a straight factory bump stop then I recommend # TGMRG30 which is rated for 3,600 pounds which is still more than enough for this application. The springs will help prevent the van from sagging at the back and reduce that side to side body roll feeling when turning. I have included links to the installation instructions for both...
