7,000-lb Capacity hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. Provides a comfortable ride by absorbing road shock and improving stability. Ideal for trucks with slide-in campers or an in-bed salt spreader.

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.

7,000-lb Capacity hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. Provides a comfortable ride by absorbing road shock and improving stability. Ideal for trucks with slide-in campers or an in-bed salt spreader.Product arrived right on time. Installation was easy. Product was of excellent quality and just as advertised by etrailer. Timbren rear suspension enhancement system. I pull a 32' fifth wheel.
Yet another great experience with etrailer! Product arrived in time and good packaging. The timbren springs work great to keep my truck level when hauling my gooseneck and tractor!
Easy to put on .took me about 35 mins for both sides. I pulled my RV same day and worked like a champ. The factory parts on my F 150 were a joke. Also hardly any rear squating ,my truck stayed level and the ride was 100% better.
Easy to use and to attach to the frame.Holds up well to heavy loads.
I have a Half-Ton Jayco Eagle Lite 5th wheel. My brother installed Timbren SES on his truck and with his encouragement, I purchased a Timbren SES from eTrailer. It took only 20 minutes per side to install. Before Timbren, my truck suspension would lower 2-3 inches with the 5th wheel. After Timbren, my vehicle is perfectly level at all times, the ride is very smooth. I strongly recommend this product to anyone that needs to enhance their vehicles' rear suspension. A great product. My only regret is that I did not make this investment sooner!!!

Great product, ordered these for my F-150 and was upgraded to express shipping. Received product in 4 days and took me a total of 20 minutes to install on both sides. Truck does not squat at all when it comes in contact with the springs now. Still have the smooth ride when not towing, towed my trailer with 4800lbs with no problem. Thanks for a great product.

Still working the same as new. Towed 6500 lbs. and truck set normal. Still a great product. Thanks again!
Easy install in my 2007 2wd F150. pulled a 4800 pound 26 foot travel trailer 200 miles the next day with no issues. Along with adding a load leveling hitch, I couldn't ask for better upgrades for this truck. My wife couldn't feel any buffeting when tractor trailers passed, and we pulled at 60 to 65 mph.
Turned my 1/4 ton into a much better and stable hauler
Springs were EXTREMELY easy to install, no more than 30 minutes total. Pulled a rental camper up north and had some squat and sway issues, even with load distribution hitch.
Ordered the springs and had them shipped to the campground, installed them on site. Should be a good comparison how the camper handles on the way home!
So far, very impressed.
Awesome product , makes my truck ride kinda stiff when the weather gets colder in Northern Indiana , But really works better that air bags when I tow my Trailer .
I like them well enough, but my wife had complained that the ride was too rough after. I removed the spacer and it seems to drive better in town. I haven’t towed my trailer yet, but it was very nice when I had the spacer in last summer.
I got these for my 2015 f150, my truck doesn't sag anymore when I have my trailer hooked up.
works better the air shocks
Arrived a day early, and everything looks to be in perfect order. Will be installing these on my 2014 F-150 SCrew over the weekend. Looking forward to seeing how they perform.

Installed in about 30 minutes used a lift without any issues. Have towed my 32 travel trailer over 4000 miles and performs great. The truck is solid when under a load and no difference than stock when not.
The product came in 3 days as I picked. It came in nice box and packed well. First inspection of the product is exactly what I wanted. Will be installing today and towing my travel trailer soon so I will leave a future comment.
Rather stiff now but great for traileri ng.
Have them in the front and rear and work great! The rides a bit rougher but does the job I bought them for!
Has eliminated the bouncing previously experienced during highway travel. Easy to install and a simple solution. +++
Excellent for towing , not smooth driving without a load .
I didn't like the ride after installing. The ride was so bouncy I had to remove again.
Just as advertised. Couldn't be happier. Arrived on time, install easy and performance great.
Great Experience ordering this product. Items arrived when promised.

I have towed my 5th wheel several thousand miles over the past year since installing the Timbren SES purchased from eTrailer. Not only have I been very pleased with this product but have shared the plus features and good news of this product with many other half-ton towers.
