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. 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 because the rubber has more travel.

8,000-lb Capacity hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. Provides a comfortable ride by absorbing road shock and improving stability. Ideal for trucks with slide-in campers or an in-bed salt spreader.Towing a 3 horse living quarters gooseneck trailer with a Silverado 3500HD 4WD diesel with a standard suspension . The Timbrens reduced sag by a couple of inches and improved the ride and handling significantly, especially over rough roads. Installation was simple and took less than an hour. Very happy with this upgrade.
after hooking up my 5th wheel camper, We went for test drive, they changed the ride to rock solid and ruined it, I returned to the and removed them, Big mistake on buying them I'm ordering Air Bags like I should have in the first place
After a year of ownership and towing my toy hauler many times, I’m happy I went with Timbrens as opposed to air bags. Easy install, maintenance free, and they really do help keep things level.
Removed air lift bags and installed Tim bren
Added these bump stops to my GMC Denali 3500 to help improve towing my fifth wheel. They do a great job of preventing the bed from sagging under heavy load. The truck is perfectly level with 3000+ pin weight on the hitch. The truck is extremely stable when the load is sitting on these rather than just on the springs. They do limit travel of the rear suspension (which is exactly what they're designed to do) when not under load. So with no load on, some big dips or bumps that would normally be absorbed by the suspension travel cause the suspension to hit the bump stops instead. It's well worth the tradeoff though for the added payload capacity.
These are a must have for a slide in camper. I am one my third truck and these are my third set.
They weren't bad but when they bottomed out it hit hard so I purchased airbags to replace them. I don't recommend for truck camper use.
I’ve had Timbrens in the front of my last two trucks for plowing and I have been more than pleased. The truck rides just as well. I decided to get a set for the rear of my 2020 Silverado 2500HD to help with my gooseneck equipment trailer and truck camper. Installation was a breeze, maybe 10 minutes for both sides. I highly recommend them, and I highly recommend etrailer.
They work as described,happy with the purchase & installation was a breeze
After 1 year hauling a 16K fifth wheel up and down the east coast, the Timbrens are working great. Smoother ride, no sag. Mechanic installed them in 15 minutes.
Waiting to see how they do with my 5th wheel rv. Easiest install I've ever done.
Very easy install. Didn’t want airbags. This is perfect for towing my 4 horse gooseneck trailer.
Items were exactly what I needed, description was spot on. Super fast delivery.
Extremely "easy" to install. Took me almost longer to get my jack, some boards together and soap than it did to install this product. Shipment came quicker than I paid for it to come. Wow! Very pleased with Samantha's customer service!
These are my third set of Timbrens on the third truck in a row. I installed them in about 45 minutes by myself in 105 degree Texas heat.
I've been using these for a month now. I decided to give these a try instead of air bags. So far I've been please, Yesterday I had 2,500 of tongue weight (I have a scale on my hitch, it's super handy btw) on my 2021 2500HD and it handles very well. These didn't allow the truck to sag, so the truck bed was fairly close to level (so a very slight sag). But without these, my front end would've looked like it was way higher then the front. So far, I'm a believer in this product, 10 minute install and your set
Easy installation 2019 Silverado Hight Country 3500 4x4 single axel, if you can lift the rear of your truck as we do. The only thing is when the truck is under no load and we drive it the rear suspension will bottom out and kit the suspension enhancement system when we hit a pump on the road. Its sudden and it can be felt by the crew in the truck. Under load they work great.
Work great. Offer stability, especially in corners. Do not provide for a level truck as the weight of the camper still compresses the springs up to where the Timbrens engage, but I knew that going in. Alternative to full-on air leveling systems.
Got excellent coaching on the proper part for my 2020 GMC 2500 HD. The new horse trailer did not exceed the the weight limits, but squatted the back end more than I wanted. These new bump stops worked perfectly. Install was easy, and the truck rides like normal without load and rides better with load, so its a win win. Thanks for the quick shipping, follow up, and always having great reviews to read when selecting parts to purchase. THANK YOU ALL at "etrailer"...
etrailer never disappoints. Installation was easy, did not have to raise truck axle per directions. A small amount of bearing grease worked better than the recommended soapy water. Cannot comment on effectiveness yet as I am still awaiting delivery of our new truck camper...more to follow.
Arrived fast and installed in about an 30 minutes.
Removed the old bump stops with couple screwdrivers.
For the new install, don't waste your time with soapy water (I tried it)...just use liquid soap without the water...worked way better. Coat the entire top and 1/4 inch down the side to the first indent.
I used a flat 15 inch pry bar to help push them in. I then jacked the truck up and put a piece of wood between the stop and the axle and lowered it. Helped seat them fully.
Installed on a 2021 Chevy 3500 4x4 dually.
arrived fast and was easy to install
Etrailer provided me excellent service. One of my Timbren bump stops was lost due to my fault. I needed another set very quickly. They made sure they were shipped promptly and followed through to make sure that I had them in time. Excellent customer service, and unlike amazon I was able to speak to real people who cared.
I have purchased a lot of things from etrailer and they never disappoint. The products are always as they say they are and the shipping is above average; meaning most of the time is before the quoted time of delivery. The Timbrens went right on no problems. Thank you etrailer!
Works great

These things are bullet proof! Air bags are for old people who never leave the pavement.
