6,000-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 work great for giving you a solid towing experience when loaded heavy; however, when driving empty you definitely get the jounce bumper “into the air” experience when driving on moderate to rough roads. I have the recommended gap installed between the axle and the timbrens, but with terrible midwest roads and highways it doesn’t seem to be enough gap. Smooth roads it rides great. It’s driving 80mph on the expressway and hitting potholes or large cracks where these will hit causing uncomfortable harsh ride.
I’ve resorted to installing and then subsequently removing these anytime I use my travel trailer for longer trips (30minute removal time). I tow a 7000lb loaded travel trailer with an f150 and just needed something to make the soft half ton suspension from porpoising too much on bad-roads. Mission accomplished when towing as I said these things work great for heavy loads. It almost rides better with heavy loads…. I was going to give airbags a try but the reviews from others have scared me from those because even with airbags at the lowest setting you still get the jouncing on bumpy roads.
They do exactly what I wanted them to do. They support my boat trailer and when not towing, they don’t touch the bumpers everything’s great.

great, It saved me from going to air bags
I absolutely love it and have zero issues. Mount it and forget it. I tell all my friends to buy them. Timbren suspension is the best I've used and I've tried almost everything.
Sorry to report that the Timbren package arrived in original box that looked as though it had been ripped open and the carefully taped shut with clear packing tape. I thought at first that shipper had damaged it but all parts were there so I started install. Half way thru I discovered two of the lock nuts were stripped and threads on the right axle pad were burred at the start. We live 14 miles round trip from the closest ace hardware. I used a die to repair the axle pad threads but had to stop for the day to purchase new lock nuts. Feel like I got a used set for new price.

Oh I am not sure what happened there. Customer Service will be in touch.
They are great. My truck use to squat while hauling my 34, camper. I put these on and it level everything out.I was worried that i was going to snap a leaf spring but this took care of the problem.My truck is a Ford f-150 crewcab.
Ordered the Timbren Rear SES while camping and just now installed. Ordered because of someone's positive feedback on the SES. No issues with the installation. Soon I will be hooking up the RV and putting them in use.
Had a 2.5" leveling kit installed and wanted the Timbrens to prevent rear suspension sag when towing a 20' ATV trailer. Product works great to keep the truck level when towing and provides a solid ride (no bounce). Easy to install.
The Timbrens work great on my F150. Also Etrailer was awesome to order from as always!
I just installed the Timbren Rear Suspension Enhancement System on my 2019 Ford F-150 4x4. The install was pretty straight forward, but I will say that the written instructions were pretty vague. Reviewing the Video on the e-trailer site was helpful. Also the markings for Left and Right could be improved. The marking “L” was very small and baring readable and the “R” appeared to be under some scratch marks so it was not legible at all. I think this product will help considerably. I have attached photos. The clearance between the rubber spring and the bottom plate is approx 1”. I also previously installed the Equalizer weight distribution & 4 way anti sway system to tow my 30’ Travel Trailer. The Timbren is to prevent any slight squat may occur.

Great
Easy to install - quality product!
Boat trailer no longer causes truck bed to “sink”!
I normally don't have this problem with you folks but when I looked at the box it looked like it was open and then wrapped up with packing tape, pretty beat up. I am missing all the nuts and bolts that go with this and only received one of the spacers. Is there any way someone can send me my missing nuts and bolts? I am not terribly upset about the missing spacer as luckilly I picked up both the 1 and 1/2 inch spacers separately and those did include the bolts to screw into the bracket.

The box was definitely in poor condition. Customer Service will be in touch to have the missing hardware sent out.
The product seems very good, but the instructions are very poor. Thanks to etrailers video that gave way more info.
The pads worked well when pulling a trailer, considering the relatively low price compared to other systems, I’m happy with our choice.
This is my second set of Timbren first set was on a 2012 Nissan Frontier and now for my 2016 F150 and both times they worked as advertised.
I just completed installation of my Timbren Rear Suspension for my 2016 Ford F150. In 2012 I purchased this same product from etrailer for my Ford F150, which I upgraded to the 2016. I have a 5th wheel and the Timbren product allows my vehicle to be perfectly level in all situations. A great product!!!

After 1 year heavy use, I still strongly recommend the Timbren shock as the perfect solution for a level towing, hauling ride.
Solid Product! Yeah it's a stiffer ride when loaded But that's the sacrifice made to have more control of the haul while underway. Definitely recommend to anyone wanting to stay more level with a heavy boat/trailer setup as in my case.
Not that install is hard but removal of spare tire before install, may have helped with space if you don't have a lift.

Still holding up great. Have a friend that went with airbags , and is constantly battling leaks
First, this is the third truck have have put Timbren SES on, so I am a big fan of this option for a pickup truck. There is no impact to the ride when the bed is empty, when loaded it is a big improvement keeping the truck is a level position, reduced sway.. I would have given this 5 stars, except the lower bracket is rusting. All the other parts are painted black except this one part - see picture... This is after one year, truck is parked in a garage in NC (not a high snow/salt state)...

I continue to be a fan, on my 1019 f150, I used the 1 in spacer, works perfect ! I have dumped 2200 lbs of stone in the bed a few times, no problem.
I have a 2016 Ford F150 Regular Cab with 6.5 foot box and 5.0 engine, 6400 lb payload package, 9.75" ring gear with 3.73 gears with a locker. (Hard to find!) Ease of installation is easy, with even minor mechanical skills. I took my time and it was 40 minutes to install both sides. Took some measurement of the factory bump stop distances to the axle - 6.5 inch's approximately. (Would take a lot of weight to compress it that far!! Have hauled some rocks before, almost 1 ton and it was still 3 inchs from touching the axle!)
After installing I took some measurement of the gap between the plates and the rubber that will come into contact with when the suspension compress's. Left side (Driver) was 1.25 inch. (Full gas tank.) Right side (Passenger) 1.50 inch. Have not driven it yet to see how the suspension will ride before these Timbren Rubbers will come into play.
Purchased these to help when I haul a 700 Yamaha Grizzley ATV (750 lbs approx.) and tow a camp trailer with a 550 lb tongue wt. approx. Separately the truck would be level, but with both it was squatting it to much. I am hoping this helps in that situation & to help stabilize the ride.
Gave a 3 for easy of installtion, but yet to be determined how well it will help when towing & or hauling ATV or both, and how the ride will be empty.

I spoke with my Timbren representative, who tells me that its likely the full tank of gas is causing the 14 inch space differential between the driver/passenger Aeon spring and the axle. They do have spacers available that are as small as a half inch, but all that would do in your case is make the other side 1/4 inch closer to the axle. Any load thats capable of compressing the suspension so the springs contact the axle would cause both springs to contact at the same time, so that small differential wouldnt be anything to be concerned about. Let us know if youre interested in the spacer, Timbren will send you one if youre interested.
The Timbrens made a big difference. In fact, when I gave them to my mechanic to install, he said "Good choice. I have installed a lot of them on customer's vehicles and on my own."

Great investment. Could tell right away in improved ride quality while towing my RV.
A year after installing these and many miles old towing I heartily recommend them. F150 is totally level while towing a 7000 lb fifth wheel. Great economical solution to sag!
Thank you for your quick response for my need for a replacement part.
I have a 2016 F150 XLT. Max towing package. Front end has spacer to level the truck. Then when i tow it squats really bad. With the weight distribution hitch it still squats. I installed this product and you can see in the picture before and after. With no distribution hitch it’s barely squatting. Fantastic product. Nice thing it allows suspension to flex independently still unlike air bag kits.
This does exactly what you hope it will. I am not a master mechanic, but the install was done by myself after removing the tires. It picked up 3 inches from the level that was used previously.

Fine
Product arrived within a business week. Took a couple days for me to get around to installing it on my Ford 150 Lariat 4x4. Not bad to install, I had to do it laying on my back in my garage. Finally hooked up my 4th wheel to my Andersen hitch today. Truck was level, 5th wheel was level, and I was happy. Ready to rock 'n' roll.
Work exactly as advertised and just as easy to install. An hour or so and I was finished.

To be honest the ride quality is something that we hear about with Timbren springs. I do know that one way to combat it is to remove it like you do when not in use. Another suggestion would be to look at a different system like part # SS95QR from Super Springs. It is made of a softer material and is rated at 3000 pounds. Or you can look at an air bag kit like part # F2582 which has a 4800 lb capacity. When installed it will be in constant contact with the upper frame and lower axle to give a smoother ride. A couple of caveats with it are that is is not compatible with in-bed hitch; product mounts in same location as hitch brackets. Also, that the distance from the outside of the frame to the inside of the tire must be at least 8 inches. You would need to add a compressor to have a constant way to add air or you can do it manually.
