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.

8,600-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.
We pull a fifth wheel RV with a pin weight of 2400 LBS and our F350 Super Duty is always completely level. For us, the Timbren suspension system is much better and more economical then air bags.
Robert - 08/02/2022Product was easy to install, 1/2 hr taking my time. Used a open end wrench and floor jack. My 2018 F350 Super Duty Super Cab 4wd no longer plunges over bumps, it has lost all its rear end sway on turning, carries my load much smoother ( loaded all the time ). Even with the load I always carry, the vehicle sits 1” higher in the rear. Prior to the install I was constantly hitting the rubber stops on my factory overload springs.
Andrew - 06/10/2019These are worth every penny. I have used these with a heavy Toy Hauler Travel trailer (11000 lbs) on about 6 trips over 250 miles each. Then on a (14000 lbs) Toy Hauler 5th wheel for three trips over 200 miles each. They provide a great assistance under heavy loads. They especially assist with ride quality going over bridges and over pass transitions (wavy bridges). The Timbren has also made a drastic difference going around Richmond VA bypass on 295 (anyone who travels this route with a trailer knows exactly what I am talking about). I measured a 2-inch difference in squat with them vs without them. They do not impact daily driving habits and will not even notice a change. I have them on a SRW F350. Very easy installation, a couple bolts each and maybe 10 minutes. I would recommend these to anyone that hauls a camper. If you have one of them campers squats the truck, these could be a great help. Your payload is still what the MFR stamps on the truck. These help the ride amd make the truck feel in control. I have not experienced any trailer sway with these.
We travel full time in our fifth wheel camper. I installed these Timbrens on our 2019 F350 and they perform great! Keep our truck sitting level with camper hooked up. They also help improve the ride while traveling.
Purchased this product for my F350 to help reduce bouncing when towing 5er on rough roads (e.g., I95 in SC). The Timbren’s exceeded my expectations and I also gained about 1/2 inch in towing bed height. Overall very pleased.
So easy to install on 2019 F350 SD Dually. just lift the back an inch by the hitch and can work right over the tires. no need to get dirty under the truck. I only drop 1.5 inches with my current fifth wheel, so these will just come into service when i load then family. Installed in less than 30 minutes.
We carry a 4500 lb truck camper and the moment we installed these the difference was night and day. It cut down the lateral sway we had before. Installation was simple and took about 45 minutes. I would highly recommend them.
Easy to install, Easy to buy from etrailer . Makes a big difference when towing my 5th wheel RV. Helps with overall control of the Ford F350 and a loaded RV (18000 Pounds).
Bryce - 03/18/2022Works great , thanks to the expert from etrailer who help me
I love them. First you don't have to worry about them losing air, or adjusting for the load. I was concerned they may make the ride rougher when unloaded. But since they don't actually touch, until you get some weight in the back, there is no change in the ride. I have read a lot of reviews that say they make the ride a lot rougher when unloaded. I say those people either don't actual have these, or they don't have the correct ones for their truck. I feel they bounce a lot less, when loaded heavy and you drive over large bumps or dips. We have drove about 10, 000 miles since installing. Half of those towing our 5th wheel, which weighs 17K. I will never own air bags again.
We pull a 35 foot 5th wheel. Before we added these we would hit bridge overpass with a whip like jolt. Now it is very much different with hardly any jolt. Great product and very easy to install.
Super easy to install. etrailer video madder it even easier. Great shipping and service.
Helped with my 5th wheel hauling!
Easy install. Simple way to give your tow vehicle extra help with heavy trailers.
Easy to install and it took care of truck squat when towing my RV.
These are exactly what i was looking for. Decent price and fast deli very. I needed to beef up the suspension when pulling my 5th wheel. These should do it!!
Installed on 2019 F350 in which we pull a 41ft 18,000 pound 5th wheel around the country. This product took the majority of the squat out of the truck. Thru sunshine, snow ,rain and steep mountains timbrens have preformed flawlessly. Highly recommended.
Great product, easy installation. Will last. Better than air bags and components that will wear out for the weight that I haul.
They work exactly as described - installed on my F-350 for use with a 17K GVWR 5th wheel. No impact on daily driving, as a matter of fact I don’t even know they are they (until I need them)! Highly recommend
Jake - 09/09/2021Easy install on 2017 Ford F-350. For a keystone Raptor RV with over 3500 Lbs tounge weight
Great product! I had some body sway, and a little sag when loaded heavy in my F350. I have a steel flat bed so my pickups not empty when empty, these fixed my issue of it being squishy till the factory overloads kicked in.
Made the ride solid and firm, exactly what I was looking for. Makes corners great again for a heavy duty pickup, only thing a person may want to consider is if you have a heavy bed or loaded with tools, you’ll have to pick up the rear end to unload the springs enough to slip the timbren in.
Cant wait to get hooked up to the Rv and our dump trailer and see how much better it trailers, especially since it exceeded my expectations empty.
They help the truck ride so much better and takes the bounce out of the ride.
Just installed them. Your video is very good the directions that come with them are terrible.
Hooked up the fifthwheel and I only dropped 1”
With out them it would drop 3”
Robert - 11/11/2021Quick 20 minute install and made quite a difference!! Definitely worthwhile!
Great service and products as usual! thank you very much.
