Specs:
Whether you're hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the truck's weight, as well. 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 has a custom-fit bracket that will be 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, one inch 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 the truck level.
Each hollow rubber spring works independently to support the driver's 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 the truck. 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.
Compared to the Competition
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.

8,600-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.About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.
Makes my truck feel better while towing a 5th wheel camper, especially over expansion joints of the expressway.
I haven’t hooked up to the fifth wheel yet or else it might be a 5 star. Based on the 15 minute installation time and the price compared to air bags this appears to be a logical way to go. I will update this as I hook up and put a load on it.
I will say they are perfect for towing but when your not towing cause they are so close to the bottom it feels stiffer when not towing! They should make long enough so that it touches besides that these are perfect
We prefer it over airbags. No hassle adding air etc. Great under our 3/4 ton pickup with our Artic Fox camper!
Couldn’t be happier with way they operate. I haul a 12,000lb 5th wheel trailer and helps tremendously with the handling and keeps my vehicle from sagging in the rear. Great idea and very reasonably priced.
After a year on the road, and a few thousand miles of towing our 5th wheel, the Timbren bump-stops work great. Had air bags that required tinkering and always needed to adjust the pressures. No adjustments needed with Timbren.
Pros: Easy to install, no adjustments, adds stability while towing heavy loads.
Cons: Unloaded, makes driving over seriously large bumps a bit rough with only about an inch or so of factory suspension travel.
I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.
I had bought these timbrens and the weight safe hitch with the 8” drop from etrailer. I was quite please by both products. Installation of the timbrens was very easy, only took 30-40 minutes to change out bump stops in my garage.I hauled a Uhaul trailer with a Jeep over 300 miles, with no issues. The timbrens worked great, no issues with the rife. And I really like the weight safe hitch. I recommend checking out these two products from etrailer. Thanks etrailer.
What I think is that it seems like most of the installers and reviewers of this item aren't using the sense God gave a gnat. This has to be the easiest install ever. It took me 15 minutes to do the entire job including removing the old stops and installing these Timbrens. Had a friend use a floor jack under my hitch, raised it up, i pried out the old stops and inserted the new ones, let it down on a piece of 2x4 and DONE! No removing tires, no removing heat shield, no nothing. 2 screwdrivers and a piece of wood.
Received my springs today and had them installed in less then 45 minutes in my driveway, on my 2018 GMC Denali 3500 HD. I followed the advice of etrailer's videos. I pull a 2011 all aluminum self contained toy hauler and use Husky weight distribution hitch. I have not yet taken our trip to AZ from WI yet but will provide further input when we do over the 4th of July. I used a floor jack on the frame rails to provide clearance for installation and did not take the rear wheels off...worked in the wheel wells to remove and install.
Product does not help rear swag with fifth wheel camper but a half inch. On brand new truck as well. Not happy with product. Called to return them and want me to pay 27.00 shipping and stated in email that was sent to me I couldn’t return if installed. I’m not understanding this ? Do not buy ! I won’t be doing any more business with etrailer . Not helpful at all
Awesome customer service and follow up. Easy installation. Pry bar, couple of 2x4 wood blocks, floor jack and a little WD40. Weight of the truck seats the new bumpers in and you're good to go. Literally took me 20 minutes to remove and install. Can't wait to tow our 5th wheel.
Absolutely the best load supporting product on the market! Even without a load in my 2016 chevrolet 2500 4x4 the road control and handling is far greater than stock. Ive recommended this product to several friends and complete strangers. Everyone i know that has purchased this for their vehicle feel the same as i. thanks!
Easy install. Very stable ride for my one ton Chevy. I feel safer now hauling the 44’ fifth wheel. Excellent product.
These have been a great add to my truck for towing. I have a travel trailer and own a business where I use my truck for pulling. The bumps in the road feel much better with these on the rear axel. When compared to stock you will be shocked. Very easy to install and worth every penny.
My order for timbrens was received very quickly.Installation took 45 minutes.It took longer to get my spare tire out of the way.Install was much easier than air bags for sure.I replaced my ride Rite air bags with the Timbrens.Air Bags always loosing 3 to 4 lbs air a week.I had no onboard compressor.Timbrens were better for me.
Installed easily with a few blocks of wood and a pry bar.
I'm pleased with the results of the test run with cargo trailer. Next will be the 5th wheel.
This is the second set of Timbrens that I have purchased from etrailer and as always they work perfectly with my trailer and Bulldog ATV rack. The shipping is fast, prices are very good, and customer service is great.
This rating of 4 stars is because I have not put a load on my truck to test the drive loaded. I have driven it unloaded. The unloaded ride is the same as original. Installation was easy, I looked at the etailer video perfect procedure. It took 30 minutes tops. Fit perfect, easy installation, speedy delivery.
I have a 3500HD Silverado and pull a GD Solitude 5th wheel about 17k lbs. The installation was easy for this 65 year old and went well. Truck front and back fender wells measure 40in. from top of well to ground with 5th wheel connected. Rear fender well was 42in. unloaded. During our first trip after installation the ride feels smoother when on roller coaster highway.
The installation video's on this site and other YouTube channels were very helpful for the installation. Definitely glad I did the install myself.
The set of timbres has worked out great for the rear of my chevy 2500,getting the extra weight off my springs and onto the axle.
Easy install....took about 45 minutes including the time to find what I needed to install, and put the tools away....will be putting the trailer on soon can't wait to try these out...
Went on fairly easy, jacked the rear of truck up pulled out old bump stops,soapy water on new ones positioned them and with the help of two short pieces of 2×4s under each side lowered the truck, they slid right in place. Very easy. Won't be hooking up to 5th wheel for a couple of months, looking forward on how they work on truck squat. Might follow up then and give another star.
Timbrens we’re not delivered only Weath ertech
