12,000-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. 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.

These are amazing! Simple to install, easy to read instructions, very straightforward. Hardest part was taking off the factory bump stops, but I was lying on my back using hand tools.
I put these on my F550 wrecker and they alleviated the squat I was experiencing when towing trucks.
In the photo you can compare the factory bump stop with the Timbren.
In my truck I did not use the extra spacer that is included in the kit. If I had jacked my truck up higher I could have used it. As it is right now the Timbren's are always in contact with my axle. In my opinion my unloaded ride is better as well.
I HIGHLY recommend these for tow trucks.
These work great on my F450 with towing my 21k lb 5th wheel. Also help the ride when unloaded. A cheaper alternative to airbags, and it took me about a hour and a half to install both sides. Very happy with this product

I like the Timbrens more. I am in the middle of a cross country adventure 4500 miles so far and the Timbrens are preforming great. And I am not a interstate rider, we take the rig back country, up and down 8 grades, twisty roads and bumby roads. Could not be happier.
We purchase the Timbren Suspenstion Ehahancement System for our 2021 Ford 550 plumbing truck. The F 550 plumbing truck has a full height 6'x 12' custom made enclosed steel service body. At the time of the purchase our salesman explain that Ford makes 2 versions of a F550 cab and chassis. one F550 light duty 17,500- heavy duty 19,500. We purchased the F550 light duty thinking we did not need that much carry capacity and lowering the overall purchase price.
Once the truck body was custom made and we drove it around for a few months we notice that the light duty suspension was a little soft due to the max weight we sometimes are hauling.
This is when we look into purchasing the Timbren Suspension Enhancement System. Once we installed this system we right away notice a big difference in the stability and handling of the F550 truck and are very impressed due to the cost and simplicity to install the product. Now after 1 year with the Timren Suspension we are very extremely happy that it is performing as well as the day they were installed. We have had no issues and would purchase this product again without any hesitation.
Thank you for a very well made suspension product that meet are need.

Showed on time and easy installation. This is why I continue to be a loyal customer.
A great product and great service again.
Springs hold up good really helped out with the problem. My F450 squats less than before.
Both people that I spoke with were extremely willing to help. Item ordered actually arrived quickly.
Easy install, can’t wait to road test with a load
I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.
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.
Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.
The pro: The longer, heavier bump stops worked great when hauling my mustang home from Chicago. The truck stayed level and handled great.
The con: I had to remove the bump stops for everyday use. They limited my suspension travel causing a stiffer ride.
I am so glad I bought these for my truck. I was able to install them myself using a jack and jackstands. The ride is bit rougher now; but the suspension is totally awesome compared to before. I am able to haul a bit more weight when needed.
Haven’t had it on long, but so far so good. 1999 F350 dually. Bolted up nicely. Total job took 10 minutes. Have hauled two gooseneck loads of hay and truck drives SO much better. Nice and level. Money well spent so far.
very good product ,received just in time and fit perfectly on my GMC savana 2000 .Be sure to clean the two receptacle thats help.
très bon produit , reçu dans les délais et s'ajuste parfaitement . Assurez-vous de nettoyer le receptacle cela facilite l'installation.
The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer
Definitely a must have when towing..stiff without a load but night and day difference while towing my travel trailer, better traction, steering and braking. Easy quick install..only issue I had was with the long bolts they sent with the spacer kit (optional for lift) the bolt diameter was too wide to fit through the holes on the bracket..but a trip to the local hardware store took care of that.
