8,000-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:
When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle 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 vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.
The Timbren system has a vehicle-specific 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 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 provides increased resistance, stiffening the suspension and keeping the vehicle level.
Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 hauling off-center loads.
Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping 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 passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.
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 as 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 - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

The system made the empty ride way too rough. I only left it on the truck for 2 weeks and then took it off however after being installed it was not returnable. I ended up going with Roadmaster active suspension and I'm very happy with that choice.
I cannot review this product yet because I have not installed it. The package arrived missing one of the main necessary parts, so now I am waiting for etrailer to ship a replacement. I need this installed ASAP, so I can complete a job. It was a disappointment and inconvenience when things did not arrive as planned. Also, etrailer keeps referencing my orders to Courtney, which is not my name, or whose name was used in the order.
Katrina B - 04/26/2022A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality.
Cannot give a review at this time. When I received it, the first thing I noticed was the box was beat up pretty bad and was wrapped with a lot of tape. When I opened the box, there was only 1 bracket and no bolts or instructions. I contacted etrailer and they are sending me the rest of my parts. I hope they arrive quickly. etrailer should have inspected the box when they saw how beat up it was
Helps with limiting rear suspension saging when towing 5th wheel RV.
Fast shipping and always great service. There install videos they do are always helpful. Highly recommend purchasing products from them!
Mounted on 2010 F-250 4 x 4 truck. As soon as you open the box, you realize that this is a heavy duty bracket and bump stop replacement. Much better quality than OEM. I did not use the spacers because I wanted a normal ride until there was a load was on the truck.
I've had theses installed for about a year and are great. No ride difference when not towing a 33 foot trailer. With the trailer it only dropped about 2 inches with no ride difference when towing. Easy to install. I reconend this.
They worked great until one of the rubber coils fell off. The housing remained but the rubber coil fell off!!! Not worth the price. I would never buy this again.
I've ordered from etrailer previously, and this is my third set of Timbrens, as I was very pleased with the performance of the previous sets, and the fact that they don't engage until the truck is loaded, and don't require any adjustment or have any moving parts. The installation is easy on a new truck, as everything is clean and the bump stump fasteners that need to be removed aren't corroded. I upgraded to the heavier set of Timbren's this time, and needed to jack the truck in order to fit the spring and spacer between the Timbren mount (on the frame rail) and the axle stop. If I had elected to omit the spacer, I would've been able to install the spring w/o the spacer. However, I wanted to reduce sag when trailering, and am willing to sacrifice some ride comfort. The Timbrens are engaged now w/o a load in the truck (only an auxiliary fuel tank), and the rear of the truck now sits 3/4" higher than on the OEM spring pack (incl. factory overload leaf springs). I have not had a chance to run loaded and unloaded, but am hopeful that the unloaded/no trailer ride will not be too harsh.
The TIMBREN rear suspension parts that I installed on my 2015 F-250 Super Duty fit and function like they said and are nice because they stay on the vehicle for ever and there is no maintenance. If you are carrying a lightweight Slide-In Camper or one that is well within your vehicle's GVW,PAYLOAD AND RAWR, this product will more than be adequate.
Excellent product and so simple to inst all.
It arrived in 3 days and only took one hour to install. This is my second set. Put the first set on a 2009 Dodge Ram 1500 & this set went on a 2016 Ford F-250 Super Duty Diesel....very satisfied,
The Timbrens are great, I do have to say they ride rough if you put the spacer in with them, but if you take out that rear spacer and run the bushing and the metal, it rides just as how it rode from factory. I pulled a loaded up trailer and the truck doesnt squat at all. If you tow a big trailer on the regular like myself (landscaping industry) these are a must. Even ordered them for my other work trucks too.
Arrived on time. Installation went well. Pleased with how well the Timbrens leveled my camper. Still very good ride when camper not on my 2015 Ford F350 Super Duty dually. Very satisfied with this product.
The parts were all there and putting them together was as advertized in the instructions. I can't wait to load up the camper and test drive the 350 super duty.
Great product easy to put on. We haven't towed our camper yet so I can't really say how it well it works.
Products arrived as scheduled, installed very easily. Works better than anticipated
Peter - 04/14/2020These arrived as scheduled. The look good, well made. On my way out to install them now. The will get tested later today on the way to the lake.
They went on with no problems, other than moving the (I call them donuts) donuts to line up with the stop.
Didn't hold up
Product shipped quickly. Looks to be high quality and a straight forward install.
Easy to install.
