8,600-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

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.

Fairly easy install. Timbres makes quality stuff.
Quick and easy way to prevent sagging of the rear end under load, great handling while driving as well.
Only difficult part is getting the first bolt in place. Very straigt forward install.
Had a problem with online catalog which resulted in me ordering wrong part.
Joshua sent me the correct item and a return for the wrong one, in a timely fashion.

Greatly helped the roll of the workhorse frame
About 15 minutes to install and made a huge improvement with a loaded bed or trailer hooked on!
Top brand
Easy to install and worked great ! Highly recommend!
These installed very easy to install.
My truck doesn't wonder all over the road now with a load in it.
Really helps my truck when I am pulling my fifth wheel.
Helps a lot with trailer loads. Would buy again.
Easy install and does what they say its suposed to! Do seem a little stiff, but time will tell as they break in. Stopped my rear end sagging issues with minimal expense, and repair time.
2021 F 150 The brackets that hold the rubber bumpers has a nut that was welded off center on both brackets.
We drilled them out and put 3/8 bolts in with locknut.
Fast shipping and e mail communication takes about an hour to install.
Great for the heavy load. Doesn’t help sway that much.
Best available for KiaI wish I would have known about this product sooner. I have a Kia Sedona and there are only 2 suspension aids available. I previously had the Firestone airbags and don't recommend. The bags and compression fittings leak and installations complicated.
This was the only other option so I gave it a try. Very glad I did. They do exactly what they say they do. The Sedona doesn't dip nearly as much when I put the trailer on. In fact I had to go to my lower rise hitch so it would sit flat. Ride is solid, but not jarring. I don't really know about the reliability as I've only had them about a week, but it's a very simple concept so I can't imagine problems. They are basically oversized flexible bump stops and have no moving pieces. They seem expensive for what they are, BUT installation is MUCH cheaper than the airbags. It cost me just a bit over a hundred bucks to have them installed at a local service chain (Tuffy). They also are very discrete so your warranty likely won't be called into question.
