6,000-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.
Great product. Great idea and works as it should. Didn't give a 5 star because the mounting bolts were a little on the cheap low quality side. But other than that no complaints
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.
Great turn around I needed this before our trip! And it got to my door within 4days of placing my order.
Thank you!
Excellent product and even better service. Highly recommended. I literally called on a contract job and while on the phone they processed exactly what I needed. Install was even easier. A Plus. Repeat customer again and again. Only gets better!
Haven't had an opportunity to put these on yet. Heck, haven't even bought the travel trailer that makes these necessary yet. But they look like what I need and they seem well built. I'll update when the time comes.
Arrived quickly, as stated in add. Easy and quick install, definitely firmed up the rear. Second purchase from e trailer and have been satisfied with both.
I have a full 2500 lb. capacity in my Ford F-250. The truck no longer "SAGS"!!
This is a great product......Thanks
added these to help with weight carrying on my F350 dually. Installed easily and doesn't really change the empty ride quality.
Good stuff. Solved my problem. Easy ins tallation.
etrailer was very helpful in getting the products I needed quickly.
I appreciate the fast response to get us the item that was lost in transit. We will be doing with you in the future. Thank you.
Product arrived on time and does exactly what it describes. Little stiffer ride without a load but with a load it made my truck handle so much better at low and high speed.
Makes my F150 town my trailer real good
I have a 2021 Silverado high country 3.0 duramax 2wd. It has the adaptive ride control. This product does reduce squat however , I couldn’t imagine towing any distance with them installed. Very rough ride. I need to find a better solution.
They work great. Hauled my camper about 3hrs with a 325# tongue weight and the 4runner sat flat and drove great. I like these better than air bag and they install in less than 30mins. No more inflating and deflating then inflating and deflating for the trip home.
The shipment tracking system is the best I've seen. The pricing matched what my mechanic brother-in-law could get.
Excellent service yet again, as always thank you Etrailer
Awesome communication, got my entire order when they said I would. Everything is great !!!
Arrived early; easy to install, and damped all aspects of truck ride considerably; especially when towing. Love it.
haven't had a chance to install yet too cold out.if possible send again in a couple of weeks and I will leave you a review thanks.
Put them on my 2018 gmc 2500 and it rides like there is no trailer behind us. Well worth the price
Excellent product that was easy to install. These definitely helped to reduce the sag while towing. However, they did make things a bit more bouncy when going over bumps. I'll take that over the sag and swaying of my trailer any day.
Installation was as expected. It came in a very fast time. I haven’t tried them with a load on the truck but I’m sure they’ll be great.
Arrived ahead of schedule, thank you.
Will install this weekend hopefully if weather permits.
Fair pricing and great service...
Thank you
Great product very easy to install. Levels truck back to factor height when loaded and makes for better cornering with out affecting ride good job.
