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.These keep my truck level with my slide in camper on board. It no longer rests on the helper springs. I have gained over 2” of height on the bed. Super easy to install. They also are noticeable on corners. Not nearly as much lean.
Took about 45 minutes to install. But that was 2 trips into the house cause my deep drive sockets were buried. F-350 gasser with 8’ box, Fiberglas cap, 200lb wooden storage drawers and estimated 400lbs in tools. I tow a 14k bumper pull dump that squats the truck. I installed the spacer with the timbrens and it sits on the original axle stop. Ride quality is unknown as I haven’t driven it yet.
These are great!! Removed the sideways motion in curves, removed the front/back rocking motion when crossing interstate bridge joints, and made the truck level with the camper attached. Simple installation as well.
It looks like they are going to do the job. Easy install even had to take one back off to remove spacer. Gained back at least 1-1/2. Truck sits at least an inch off overloads. Little pricey I think for what they are but lot cheaper than air bags. Need to take after photo in day light.

This is an absolute MUST have item if you are hauling with your truck. Hands down the best investment in suspension technology. No sag thanks to the addition of the 1” spacer. My 24,000lb triple axle 5th wheel with a pin weight os 4,000lbs is towed effortlessly from a single axle F350 cross country with no sag at all. My truck sits absolutely level. The helper leaf springs are not engaged and the truck is smooth and extremely stable, even without sway bars!!
Love and highly recommend this product to every SuperDuty owner i meet.
Best investment ever.
We travel full time in our fifth wheel camper. I installed these Timbrens on our 2019 F350 and they perform great! Keep our truck sitting level with camper hooked up. They also help improve the ride while traveling.

The Timbren suspension really makes a difference over the factory bump stops when hauling our 5th wheel. The truck is not rear heavy and drives significantly better. Its a great safety device and doesnt reduce the ride quality when hauling. Id HIGHLY recommend these to anyone who is hauling a load. Great product, too bad the manufacturers dont use these in the stock trucks!!
Perfect fit. Installation was pretty easy. Took me about an hour for both sides.
This helped prevent the squat in my F-350. It also made the truck more stable when towing. I tow a 44' Montana fifth wheel. I don't even know they are installed when driving with no load. I love them!
Installation was simple, took all the squat out of my 2022 F350 when pulling a goose neck 3 horse living quarters horse trailer
We are full time RV’rs and travel every 7-14 days and these Timbrens have been awesome, put them on and forget about them, you never have to worry about airing up air bags! Highly recommend to anyone close to their payload. We have towed about 7,000 miles this year with them.
Product was easy to install, 1/2 hr taking my time. Used a open end wrench and floor jack. My 2018 F350 Super Duty Super Cab 4wd no longer plunges over bumps, it has lost all its rear end sway on turning, carries my load much smoother ( loaded all the time ). Even with the load I always carry, the vehicle sits 1” higher in the rear. Prior to the install I was constantly hitting the rubber stops on my factory overload springs.

Excellent! I have since purchased another set from you for a 2019 F350 diesel. These things are just the ticket! The ride and handling is so much better!
Very easy to install and works well. Truck does not squat as much with a heavy trailer so you may need to adjust trailer hitch to insure trailer is at desired "levelness".
The Timbren SES is an awesome upgrade to help with sagging and stability when pulling a heavy load. Bolted right up with zero issues. Took about 30 minutes to install. The tech support at etrailerb are most helpful and the package tracking info is great.
Purchased this product for my F350 to help reduce bouncing when towing 5er on rough roads (e.g., I95 in SC). The Timbren’s exceeded my expectations and I also gained about 1/2 inch in towing bed height. Overall very pleased.

I remain very pleased with the Timbrens performance.
Eliminated the bounce and instability associated with driving over really crappy interstate roads, especially the highway bridge transitions!
Product was as described. Customer service keep me informed on the shipping and delivery progress.
Etrailer has always been great for me.
Great product! I had some body sway, and a little sag when loaded heavy in my F350. I have a steel flat bed so my pickups not empty when empty, these fixed my issue of it being squishy till the factory overloads kicked in.
Made the ride solid and firm, exactly what I was looking for. Makes corners great again for a heavy duty pickup, only thing a person may want to consider is if you have a heavy bed or loaded with tools, you’ll have to pick up the rear end to unload the springs enough to slip the timbren in.
Cant wait to get hooked up to the Rv and our dump trailer and see how much better it trailers, especially since it exceeded my expectations empty.
So easy to install on 2019 F350 SD Dually. just lift the back an inch by the hitch and can work right over the tires. no need to get dirty under the truck. I only drop 1.5 inches with my current fifth wheel, so these will just come into service when i load then family. Installed in less than 30 minutes.
I ordered these for my 2022 F350 SD because I haul a 14,500 lbs 5th wheel camper and didn't want air bags. Ordered them, arrived in four days and installed as the directions said. Installed in 30 minutes after removing the factory bump stops. Easy as can be. No ride difference without the 5th wheel attached as they don't make contact until loaded. I loaded 5th wheel camper and noticed right away the truck didn't sag like originally. I would recommend and purchase again if I purchased another truck.
Absolutely excellent service delivery was on time and product is exactly what I needed. I shop in trailer because the description that you read is what you get when you receive your product.
Easy enough for someone like me to install, you do not know they are there when you are running without a load on. With my fifth wheel on, super smooth ride.
The order came promptly and was delivered in perfect condition. As indicated by others, they were easy to install and I installed them in twenty minutes. One of your other customers stated if you jack up the rear of your truck you can work over the rear tires without having to crawl under the truck. It worked perfectly! The pictures are of jacking up the truck, working over the tires, and final installation.
My wife and I are full time RVers. We bought these to take some of the sag out of the rear of the truck.
Installation was a breeze. Very straightforward. The function has been excellent.
They work so well and require so little maintenance and attention that you’ll forget you even have them on the truck until you get an email asking you how they’ve been for the last year ??
Excellent product, excellent service from E trailer. 100% recommend.
added these to help with weight carrying on my F350 dually. Installed easily and doesn't really change the empty ride quality.
