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 when loaded. 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 when loaded or towing because the rubber has more travel.
I purchased this because I tow a 9000lb travel trailer. This made a big difference.
Makes my F150 town my trailer real good
Seem to be a good product. I've put them on but have not driven yet. They are much better than the one I took off. Price is a little higher than I wanted to pay but I didn't want have to replace anymore. These may last as long as
Thanks
I can always count on etrailer and Timbren for products I can count on, delivered on time!
Great product. Less sway and have recommended these to others
This was so easy to install, you DO NOT need to take rear tires off.. 60 Minute install. I went without the additional spacer to allow for a little nicer ride when empty. Very well made
Timbrens arrived on time and packaged well. Very easy to install. Have not used them under load yet but with no load then ride is the same as it was before installing them.
Very easy to install and keeps my 4runner from dropping down pulling my trailer with my atv on it.
I ordered these on July 4th (Wed) and received them on Friday. As always I got very fast shipping from etrailer.com.
I installed these today on my 2009 Sierra 1500. I pull a 20ft enclosed trailer all around the mid-west and up and down the East cost. I've continually been adding things to the trailer so lately the rear of the truck has started to sag a bit when towing. This product seemed like a reasonable way to help remove the sag. I measured the truck in a couple of places near the back with the trailer hooked up prior to installation. After installation the sag was reduced by an inch to inch and a half which is what I was looking for. The truck is now very level with trailer attached.
Installation was very easy as the mounting point is easy to get to. I did one side at a time by jacking up that side and removing the tire/wheel. I probably could have done it without removing the wheel, but this just made it that much easier. Remove one 10mm bolt on the original bump stop and then bolt on the new part. Tighten and you're done (well, I had to put the wheel back on, etc.) I did the whole thing in about 40 minutes.
I haven't pulled the trailer yet with these installed, but I've already gotten the primary result out of the purchase which is to remove the sag in the truck when the trailer is attached.
Very happy with the results on my Honda Odyssey I recommend 100%
The item arrived and installed in under 40 min total. The installation was much easier than expected. Chose not to install the spacers per the suggested directions allowing a half inch to three quarter inch between the joist spring and rear axel. Was able to install without lifting the truck, doing both sides from the wheel well by simply reaching over and around the tires.
haven't had a chance to install yet too cold out.if possible send again in a couple of weeks and I will leave you a review thanks.
Product showed up on time and packaging was great. Very easy install, literally all that was needed for install was a 15in socket and ratchet. I installed on a 2019 F250 XLT crew cab 4x4. I will update after next weekend to see how the do once I pull my 5th wheel toy hauler. etrailer is awesome and will return to buy more products from them.
Easy to install and so far they are working just fine . I haven’t hauled a heavy load yet but I think they are good
Love the extra support for my pilot....great investment!
Rough ride when not loaded but no more sag in the rear. Does the job!
Your company ships right away and very helpful web site easy to use have not installed yet but will let you know asap thanks for your help
Works great even had my nephew buy them for his Dodge truck
Definitely worked as advertised, very easy to install.
Etrailer did an excellent job. 2 day shipping for less than $8. No brainer. Staff was helpful on the phone answering questions. I ordered online and that was easy as well.
Product: these went on 16 F150 4x4 supercrew with tow package and e rated upgrade tires. I use the vehicle to pull 7000 lb travel trailer. Purpose for the purchase was to help with sway and slight sag in the rear. I use a wdh with sway but that was not performing good enough. I choose these after some research.
Install: easy. I didn't use a jack or lift. I just assembled with one inch spacer. I had an inch between the bottom of the timbren and the stop plate. I am no mechanic.
Unloaded was pretty much what I expected. You hit a big bump, you get some jarring. 90% pleased.
First tow with 16'6" boat (full windshield). The timbren was not engaged from the weight of the boat. Bumps were a little ruff. Added weight from equipment will take care of the space and ride should be better. 85% pleased with towing the boat.
Travel trailer tow. Almost completely leveled truck with combination wdh and timbren. Was able to comfortably tow. Took out most of sway I had experienced. Almost 0 bounce, even at low speeds. Basically did everything I wanted it to do. 95% pleased.
4 stars because the unloaded ride is stiffer than I would like and pulling the boat maybe a tad ruff without equipment. This will be especially true in ruff roads. But at half the cost of air bags and ease of installation I do think they are worth the money. Would recommend to those that do not mind a rougher ride every now and then.
Keeps truck level. Only down side is it makes for a harder ride when compressed
My favorite part of this product was the easy install,it took me like 10 minutes and it was ready to go.
So far I’ve towed 3500lbs on my trailer with a 2000lb double axel trailer and my truck was staying level.
Loving it so far!
Its ok but not that differences, highly recommended for air bags instead these
Great Product, it helped with body roll when loaded with my Truck Camper
These did wonders for body roll when towing my fiver.
