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 Suspension Enhancement System. This is a custom fit part. It is designed to fit the 1988 to 1999 Chevrolet and GMC C- and K- Series Pick Up Trucks 1500 Site 00:00:11 Series and also the 1988 to 2000 Chevrolet and GMC C- and K- Series Pick Ups 2500 Series. On any custom fit part, I always like to recommend to go to our website. Use our fit guide. Put in your year and model vehicle and it will show you if this will work for your application.

This part will improve your suspension, handling and safety of your vehicle. It does provide additional support as needed, so you'll always have a nice, smooth, comfortable ride. It will allow release for an ample movement while cushioning any light loads, and it will not affect the empty ride of the vehicle. These springs will become more rigid as more weight is added. It will give increased stability, provides performance while hauling heavy loads, and it will help reduce vehicle sag. They do work independently side to side because it will help compensate for off center loads, and it will reduce body roll when swerving or turning corners.

They will also act as shock absorbers taking the brunt of bumps and rough roads, and they will help extend the life of your vehicle suspension. This part will include everything shown here on the table. It includes these two Aeon hollow rubber springs, the vehicle specific brackets and spacers. The hardware for installation and a nice set of detailed instructions. When you do install these they will replace the axle bump stops on the frame. There is no drilling required when installing these.

The weight capacity is 3,000 pounds. You do want to make sure you do not exceed your vehicle's weight carrying capacity. This part is designed to work with a suspension system that is in good working order. That should do it for the review on the Timbren Rear Suspension Enhancement System.

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!

  • What is the Towing Capacity of a 1995 Chevrolet C/K Series Pickup
    There are several different towing capacities for a 1995 Chevrolet C/K Series Pickup. These capacities will vary depending on engine size, wheel base, drive type, gear ratio, etc. Therefore, the only true way to tell what your trucks towing capacity is would be to find both the Gross Combined Weight Rating (GCWR) and the Gross Vehicle Weight (GVW). These figures can be located on the information tag inside the drivers door jamb. If you subtract the GVW from the GCWR, that will give you...

  • Timbren Rear Suspension Enhancement Fit for 1988 GMC Sierra 1500
    There is a Timbren Rear Suspension Enhancement System that fits a 1988 GMC Sierra 1500, though not the part # TGMRCK25D you referenced, which is only a fit for the 2500.

  • Timbren Rear Suspension Enhancement for a 1998 Chevy C/K Series 1500
    There are 2 different Timbren systems available for a 1998 Chevy C/K series 1500. If you have 4 wheel drive you will need # TGMRCK25. If you have 2 wheel drive you will need # TGMRC25HD. I have included links to the instructions for each and an FAQ on Timbren systems for you. The system you have referenced only goes back to 1999 models.

  • Will Suspension Enhancement Fit a Lowered 1998 Chevy C/K Series Pickup Truck
    A 4 inch drop is likely going to be too much for the Timbren system # TGMRC25HD. Once installed the rubber springs will be slightly above the top of the axle. Since the top is attached to the frame, a lowered frame would mean that the ride height would actually increase if this system is installed. Air Lift has some suspension enhancement products for lowered vehicles but they are designed for a 1998 Chevy C/K that has been lowered 5 to 6 inches. So you would run into the same situation...
