8,600-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. Becomes more rigid as more weight is added for great performance when you're hauling a heavy load.

Specs:
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.
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.
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.
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.
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.
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'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.
The bump stops worked better than expected.
I installed them in F 150 2016.
Very good, easy to install, greatly improved the handling and control of the vehicle.
Prompt delivery... even better than quoted!
Simple installation.
They work great, just what I needed for the heavy trailer.
it was worth the money. i pull a 41 foot 5th wheel weighing 15,000 lbs the ride and handling was better.
Great cost effective way to keep truck level. Easy install! A 15 minute job. Does not affect empty ride quality. Extremely happy with the product and etrailer.com

Really drives alot better both loaded and unloaded also!
Wish I would have taken before and after pics. HUGE difference!
Took a week to receive and when it got delivered, the box was empty. Now I don't have enough time to order another before a long trip I wanted this part for. Will likely order elsewhere next time im looking for these kinds of parts.
You sent me the 2 right ones, they have to be more careful, I wasted a lot of time, when you send me the left one I'll change the review!
Perfect fit, easy install. Should help a lot pulling my fifth wheel.
great product, truck does not squat as much when trailer is attached
Works well better ride with some weight in or on the back so the weight is on the blocks
Product was great and easy to install. It took about 30 minutes to take the originals out and put in the new one.
Easy installation great product
Great products and great service! Fast shipping is a major plus!
Product arrived late Tuesday after noon. I read the instructions and installed the product in a half hour Wednesday morning. Have not tested it yet, but I am confident that it will perform as advertised.
