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

The Timbren system has a Chevrolet Silverado-specific bracket that will be 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 one inch 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 you are used to.

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 provides increased resistance, stiffening the suspension and keeping the Chevrolet Silverado level.

Each hollow rubber spring works independently to support the driver's or passenger's side of the Chevrolet Silverado. 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 hauling off-center loads.

Because the Chevrolet Silverado handles better with the springs, less turbulence will be passed along to the trailer helping 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 passing of a semi) because the movement from the trailer is not transferred to the Chevrolet Silverado. This also works to make the sway subside quicker.

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 as the rubber springs work to prevent bottoming out on rough roads.

Compared to the competition:

Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

• Will the Timbren Springs # TGMRCK25S Work on a 2001 Chevy Silverado 1500 with Firestone Air Springs
  
• I spoke with my contact at Timbren, and he said that the Timbren suspension can work with the Firestone air springs as long as there is room to mount the rubber springs above the rear axle. The Timbren rubber springs will replace the axle bump stops on the vehicles frame. As long as you still have the bump stops on your 2001 Chevrolet Silverado 1500, you will be able to use the Timbren Vehicle Suspension, part # TGMRCK25S. If the bump stops have been removed then the Timbren suspension will not

• Where Does Timbren Suspension Enhancement Install on a 2007 Chevy Silverado Classic
  
• The Timbren Rear Suspension Enhancement System, # TGMRCK25S, mounts to the bottom of the frame rail, not to the outside of the frame rail. Under load the bottom of the Timbren spring should only contact the axle. I have included a link to the installation details for you. I have also included a link to our FAQ article on Timbren systems. This system is designed to fit HD models only. If you do not have an HD model, you would use # TGMRCK15S.

• Can Timbren Springs # TGMRCK25S Be Used in Place of Weight Distribution on 2005 Chevy Silverado
  
• A suspension enhancement system like the Timbren Springs, part # TGMRCK25S, you have referenced, is primarily designed to suspend the weight of anything carried on your 2005 Chevrolet Silverado 2500. Although they would indeed eliminate the sag on the rear of your vehicle, the tongue weight of the travel trailer applied to the rear axle of your Silverado would lower the amount of the vehicle weight applied to the front axle. This is potentially dangerous because shifting too much weight away fro

• Question on TGMRCK25S
  
• The Timbren Rear Suspension Springs, # TGMRCK25S, will install on your 2000 Chevrolet Silverado LS 2500 HD without needing to drill new holes. The top of the mounting brackets for the Timbren springs have two holes that will use the existing holes from the factory bump stop. The underside of the mounting bracket has the round surface where the Timbren spring attaches using one bolt. I have attached an image from the installation instructions showing how the Timbren mounting bracket uses the

• Will Timbren part# TGMRCK25S fit on a 2007 Chevy Silverado Classic 3500
  
• The difference between the 2007 Chevy Silverado 2500 and the 3500 series trucks is the weight capacity. The 3500 is going to have a higher weight capacity than the 2500. I spoke with the engineer at Timbren and he told me that the TImbren part # TGMRCK25S will fit on your 2007 Chevy Silverado Classic 3500, because the Timbren springs for the 2500 and 3500 models will install the same way on both truck models. These springs were tested up to 6,000 pounds and work well within those guidelines.

• Will Timbren Spring, Part # TGMRCK25S, Fit 2009 GMC Sierra with Turnover Ball and 5th Wheel Hitch
  
• My contact at Timbren confirmed that their Rear Suspension Enhancement System, part # TGMRCK25S, will work with your 2009 GMC Sierra that is equipped with a BandW turnover ball and 5th wheel hitch. Since this kit installs in the same location as the stock bump stops (which are removed) there will be no clearance issues with your hitches. This kit includes the rubber springs, mounting brackets and required hardware and installs without drilling. Please note that this suspension kit does no

• Can a 2008 Chevy Silverado 2500HD Tow a 16,500 Pound 5th Wheel Trailer
  
• The GVWR of a vehicle is set in stone. There is nothing you can do to increase the capacity short of replacing the axle, suspension, and other load bearing and drive train components. What suspension enhancement like # TGMRCK25S does is help support the load and keep the rear end from sagging. Since you have a 3/4 ton truck, you are going to be able to tow just about anything. Consult the vehicle owners manual for the towing capacities of the truck. The gross COMBINED vehicle weight rating is
