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.

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.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.
These are easy to install and work well. Road bumps are rougher when empty but not so much when loaded. I like these timbren bumpers. I have air bags on my other truck which I like too but they took a lot more time and effort to install. However you can let the air out and be back to original ride. They're nice too. If you have a truck that is loaded all the time like with a camper then the timbren are a good solution otherwise for daily driving with occasional load the air bags are superior.

I dont like them very much. Serious bouncing with a heavy trailer load.

I bought this helpers for my long trip coming up, at first it took me a bit to figure it out, since my truck and the instructions are different, but once I found out how everything went, it was a very quick process to put them on. Very happy with this timbren rear suspension system.
2001 F350 with a 30' heavy gooseneck camper. Major improvement. The only downside is, since my springs are older and sag a bit from factory, unloaded ride is uncomfortable since it doesn't have a gap. Only use it for pulling so it's okay.
Haven't tried them out yet with the trailer, but install was fast and simple. Looks great and has not changed the ride unloaded, as some reviews had suggested. Will know more after hauling horse.
I didn't know what to expect with these rubber springs, but I was pleasantly surprised. The truck rides stiffer empty, but that was to be expected. Truck does not sag at all even fully loaded or pulling a heavy trailer. Well worth the price. And easy to install too.
I never received the item so I canceled and ordered through [online store] I got it the following day. Now, months after I canceled my order, I received this empty box with and note from the mail carrier stating that he delivered an empty box.

Well that is a very odd situation. Let's go ahead and get you over to customer service and get a return properly processed for you. I am so sorry that this shipped out, even though you requested to cancel.
Easy to install and working as expected.
This is the 3rd time I have purchased the Timbren Rear Suspension Enhancement System. I have always been satisfied with the ease of installation and the effectiveness of these springs, whether I am pulling a tow behind trailer, a 5th wheel or carrying a load in my truck. The only thing I did different this time is I purchased the Timbren Rear Suspension Enhancement System with the TorkLift StableLoad Rear Suspension Upgrade. I will post a review on the complete purchase once I install these in addition to the Timbren Rear Suspension Enhancement System.
Product installed fine and worked well. They've held up well for about a year now driving in snowy conditions where salt is used. If I had to do it over I would have purchased air bags. I was on the fence and went this route hoping it would be a install and forget solution. These are stiffer and not adjustable for load leveling which creates a rough driving experience with my rig. On my next truck I'll be installing airbags.
2000 f350 drw with timbren 8950 rated spring. I originally bought air bags but the kit didn't work for my truck and I seen the timbren and sumosprings. I opted for the timbren due to the 8950 lb rating for use on my truck. These we so so simple to install like must people claim. While hauling my Arctic Fox camper I noticed a huge improvement. No white knuckle and the handling was amazing. I will always buy these in the future. With the 8950lb springs the ride wasn't too stiff either, I feel it was perfect. On the winding corners in the mountains my truck felt as if I didn't have the camper on it
Great product, has held up well. If you are looking for a smooth ride when the vehicle is unloaded, this is probably not your best choice, but works great when the truck is loaded with my camper.

Perfect
I Ordered this set for my F350 and the package arrived on Saturday afternoon. I went to the mail box to find the timbren box to be empty and resealed. I got on the phone and called etrailer and spoke with Lori who took my information and asked for a few photos of the package. She assured me not to worry another one would be on its way. That Monday was A holiday with no mail and by lunch on Tuesday I had received my package from them. This day in age it’s hard to talk to a real person when you have a issue but to get a live person on a Saturday afternoon who actually cares and follows through is unheard of. I have ordered a few products from etrailer and I would recommend them to anyone. They list the shipping process start to finish leaving no questions asked. Thanks again for being a great company.
I feel it's the best system out there. I recommend it to everyone I know.
Love them when the gooseneck is loaded
Products came before promised and etrailer matched lower price I could have gotten [online] for the same products.
Service was awesome and fast! I put them in my F350! Not being very good at mechanics I was still able to put them in myself! I haul large loads of wood and our camper. We have had great results with this product!!

Works great! We tow a 30 FT bumper puller camper. He seem to haul a ton of stuff with us to camp and these work great for the sag! I would recommend them!
Really helps my truck when I am pulling my fifth wheel.
Install went well and product is well made :)

After one year still working like day one. Probably one of the best modifications I’ve ever done to this truck. Won’t have a hauling truck without them going forward.
