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.
As always amazing customer service and products to match.
These things should have been installed from the factory. Body roll is basically non existent in a turn now, and going over large bumps, like poorly made roads, is so much more comfortable. Can't wait to tow with these.
Just installed on 2008 Hyundai Entorouge seems to work well. Only problem was that I had buy new hardware because the supplied hardware was standard not metric.
Easy installation and perfect fit!
Fast delivery and easy installation
Yes about one year ago i installed this product with excellent results so far.
Very efficient and great to work with. Will definitely use your company again. Thanks
Easy to install and working as expected.
Just as overtired , they stiffened up the ride , plus no more sag in rear ended of truck .
Order was delivered earlier than promised and was exactly what I was looking for to enhance towing with my 24 Ford F250
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!
Great service and quick shipping
Easy to order on line received my order in less then a weeks, That's what I'm talking about didn't have to leave the house.
I just installed them yesterday. Super easy, took maybe 25 minutes. Looking forward to towing my toyhauler soon.
Easy installation. Good quality.
First off the product was beat up with paint/power coating missing in several places on both. I was putting on a brand new truck with less than 800 miles on it so I elected to touch up before install. I’ve hear a lot about Timbren but never had them. I had airbags on my F350 but when I switched to a new Tundra I went with Timbrens. I’m a bit disappointed in the ride. Feels like I can feel a “bump” in the truck from the rubber pick hitting the axle when I go on a bumpy road. Thinking I should have went with airbags. As far as having a load on the truck and helping with the squat, they do as they are advertised.
Awesome investment. Benefits of airbags without the price or the hassle.
Was very easy to install and the instructions were easy to understand.
Thank you
Great Product, arrived quickly and packaged well.
Will be buying from them in the future.
Received in a timely manner and packed nicely. Instructions clear and went on easily.
Installed in about 15 minutes,very easy.I pick up my new truck camper next week so I do not know how it works yet,but looks like it will work like its suppose too
I bought a set for my F250 and like them so much that I bought a set for my F350. It prevents the vehicle from sagging in the rear when hauling towing heavy objects. Makes for a smoother and more stable riding experience.
awesome sevrice EVERY time ive worked with these guys, really REALLY fast too... good guys
Very easy installation!
Installed a set on my truck and liked it so much I ordered this set for my Dad's truck.
