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.

Beefed up my 2018 Ram 3500 dually with these. I carry a Host Mammoth truck camper(6,000#). Visited 27 states in last 12 months thru all know nds of terrain. Couldn’t have done it without Timbrens. Also very easy installation.
Thanks Pete Anderson
Pete - 06/27/2022Received my Timbrens very quickly, very well packaged. Installed them is less than 30 minutes. Have yet to hook my rv to the truck, but can see these are going to be really helpful. About 1" to my axle where my OEM bump stops were a good 7" As always etrailer rocks!! Look forward to dealing with these folks when the need arises again.
Michael - 03/14/2019 Michael - 03/19/2019I put this set on a 20 ram 3500 swd. I originally bought this set for a 3200 lbs slide in camper. Due to life that didn’t happen. However as some passed I ended up going the 5th wheel route. The 40ft trailer being heavy still in my trucks weight rating made my big girl squat a bit and had a bit of a sway. After the install The squat was reduced as well as the sway. It also improved the handling of the hole pull itself. I would highly recommend this small upgrade. Plus you can’t argue the easy install.
etrailer is a very user friendly site with lots of information, support and product reviews. Ordering is easy and shipping is fast and easy to track. They have become my go to for anything RV related!
I ordered the Timbres rear suspension enhancement system for my Dodge 3500. Was easy to install and works as it should.
Also ordered the Blaylock EZ lock pin- we’ll made although the pin itself seems longer than it needs to be. I’m sure it will work just fine though.
Installed on my 2007 Ram 3500 because I wanted basic leveling & stability under the load of my 5th wheel. I didn't want a complicated air bag system.
Summer trips in the mountains of MT & the Pacific NW. 3 months of snowbirding throughout southern AZ this winter. Very satisfied, so I just swapped them onto my new 2018 Ram 3500. I didn't let them go with my trade-in.
Just what I need, no effect when empty - engaged when I need them.
Timbren is expensive but have proven their worth so far. I have added another one of their products to my rig more improving its handling. I have run air bags in the past and these cushions far outperform that I will never go back. No maintenance and no hassle since I installed them. The were a slight challenge installing due to close tolerances and needed a medium well socket. My great friends at E-Trailer have also proven to be EXCELLENT, USA representatives that I continue to deal with and send many more customers their way.
These load balancers are amazing. Even my 1 ton gets saggy with a big weight on my hitch but these timbren have most definitely stiffened the back end to relieve the bounce and sway.
I am writing this shortly after completing the install so I am trying to tone it down a bit. Reviews of this product install suggested 20-30 minutes to complete. It took me about 90 minutes. My biggest initial concern was removing the factory bump stops. I soaked the bolts with liquid penetrant a few days before the install. The bolts came out easily. The bolts which attach the rubber spring to the bracket would not tighten completely. The nut is tack welded to the underside of the mounting plate. On both brackets, the nut was not centered on the hole and the tack weld deformed the nut. I had to chase the threads first to be able to install the bolt and complete tighten the rubber spring. One of the brackets was labeled left with an arrow pointing to the front. The left side terminology in the instructions could be more clear with driver side notation. Overall, this should have been an easy install. Product quality could be better. I am a bit concerned with proximity of the brake lines. I will have to seen what it looks like when loaded. Performance when loaded still to be evaluated.
Heather A - 07/14/2018Imagine my disappointment when receiving this order with no invoice OR Instructions in the box!
etrailer is not as good as they use to be. For me, there are alternatives and I may need to use them.
Just installed these timbrens on my 2010 ram 3500 dually. Took about 30 minutes, really simple. Im hauling a lance 1172 and tow a bass boat occasionally. I decided to give these a try to help with rear sag and ride. I gained 1.5" after install. I will update after my next trip and i see how they perform.
The Timbrens worked as advertised. Easy installation in about 30 minutes. They successfully prevented rear end truck sag when towing my 36 ft. 5th wheel trailer.
I have had Timbrens on all of my one ton single axle pickups for ten years. They keep the truck level with loads and provide the stability nearly that of a dually. They are expensive but worth every penny.
Was debating Timbrens of air bags for the rear of my Ram 3500 dually, that was squatting about three inches when I hooked up my fifth wheel, these worked great, and only allowed about a 1 1/2 inch squat, and better ride quality when hitched, and no difference when empty. Never have to worry about air, up or down, corrosion, busted bags etc. Will add to next truck!!
For my application I had to add two leaf springs to each side, then these Timbrens worked beautifully as load boosters and stabilizers when I’m under a heavy load, when unloaded they float so you don’t even know they’re there. Perfect.
This is one of the Simplist suspension modifications that I have done and has been beneficial not only pulling a fifth wheel also keeping the truck level with or new truck camper. The only fortunate thing was that another competitive item was recommended to me and I didn't go with the other product. I'm sure I would have been disappointed if I had purchased the alternative. Thanks etailer for the large selection of many product lines in your inventory.
the timbren tdr3500ca were a very easy install on my 2018 ram drw 4x4. The included spacers were needed and left about 1/2 inch clearance.
empty ride is same. Will load arctic fox 990 soon and expect great results. I elected not to reinstall my air bags, when trading trucks. I also have upper stable loads and will not miss the air bags.
ordering was easy and free shipping was fast.
curt g - 03/17/2020Ordered these from Etrailer.com and got them in three days. Super easy to install on Ram 3500. Didn't have to jack up truck. Assembled is 6.5" on Ram 3500, I had 7" to play with so plenty of room. Haven't added a load yet as 5th wheel is on order. Looking forward to it.
Walt - 03/03/2020Easy installation and excellent shipping speed! Thanks ETrailer!
I recently had an air bag fail on my truck while loaded with our Lance 855 on the truck and pulling a small utv trailer. The shop that helped me had a set of Timbren bump stops. We modified my air bag mount to gain a little more height, installed bump stop and was on my way. My rig actually rode better than it did with the air bags, so I ordered these heavier duty Timbrens and installed them. Quick and easy, and after install I loaded the camper on my truck and it only settled 1". Perfect ! I can already tell these are going to be great.
Thanks again to etrailer for fast shipping and great price !
One of the best mods I have done to my truck. No air lines to leak or bags to blow. no bs just works...
They were pretty easy to install. It has stabilized my ride, I have a Ram 3500 and have a truck-bed camper (reduced the rocking). This is the second truck I've used them on.
Just got back from towing 40' Toyhauler across Oregon; the truck handled perfect. The ride is much more comfortable than airbags(last truck)
Bolt on quick fix to sagging springs truck rides a little rougher when empty but i used the spacers they are almost always touching when loaded they are amazing i pull campers for a living. I have around 180,000 miles since install so there working great for me no air lines to pinch or rub a hole in always hold the load up where i want it
Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.
It's an awesome product
