8,000-lb Capacity hollow rubber springs sit above the rear axle to help stabilize and level your Ford F-250 and F-350. 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.

Ideal for trucks with slide-in campers or an in-bed salt spreader.The Timbren rear suspension enhancement system helped with the truck swaying side to side when the slide in camper is on the truck.

Pretty unhappy on this one. Placed the order on the 14th with a 17th delivery date. A confirmation email comes back that it's been shipped but delivery will be on the 20th. I have to delay my trip waiting for this to arrive—last piece of the puzzle. And I get an empty box. I was thinking of canceling when I got the confirmation, should have gone with my initial response. I called and was told a replacement isn't available until mid-March. That's not acceptable. Canceled to order and now have to order elsewhere,

I installed the timbrens on a F350 dually with a slide in camper. The ride was extremely rough couldn't keep the cabinet doors in the camper shut, i think they are a good product but just way to stiff a ride for our liking replace dwith airbags and compressor.
It fit perfect, I had to get a special order due to a small lift on my truck suspension but there help at timbren got me the special order number and allowed me to order through etrailer properly, where several other companies couldn't seem to get the job done because of the special order item number, so" hats off to the sales associate at etrailer". It definitely keeps my truck bed from squatting with my UTV up top and my trailer on, and very little sway on corners. Seems to ride the same with no load at all. I don't know if airbags would have been better, but for me this did what I wanted with much less work and expense. I have a F-350 S.B. (single wheel) carrying a 1100 lb. UTV atop my diamondback cover pulling a 22' trailer with 350 tongue weight.
5 stars. Easy to install and made a big difference when pulling a 9k pound travel trailer. I would recommend it to anyone pulling a trailer. Kept it from sagging and level.

Awesome and still working
The Timbren Suspension system did keep my pickup level when towing my 5th wheel trailer.
I was on the fence about air bags or the bump stops for my slide in camper on my f350 after lots of reviews I decided to go with the bump stops and couldn’t be happier my truck handles awesome going down the road.
Great product! I've used Timbres suspension enhancement products on another vehicle and they work great. No airbags to worry about and super easy to install. Etrailer is always a pleasure to work with and gets things shipped quickly.
Product fit and customer service was gr eat
All products were great.
I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.
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.
Installation was a breeze, removed old bump stops installed Timbrens in about 30 minutes. Haven’t put a load on them yet so I’ll update later. Installed on a 2008 Silverado 2500HD..
About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.
Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.
The pro: The longer, heavier bump stops worked great when hauling my mustang home from Chicago. The truck stayed level and handled great.
The con: I had to remove the bump stops for everyday use. They limited my suspension travel causing a stiffer ride.
I am so glad I bought these for my truck. I was able to install them myself using a jack and jackstands. The ride is bit rougher now; but the suspension is totally awesome compared to before. I am able to haul a bit more weight when needed.
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.
very good product ,received just in time and fit perfectly on my GMC savana 2000 .Be sure to clean the two receptacle thats help.
très bon produit , reçu dans les délais et s'ajuste parfaitement . Assurez-vous de nettoyer le receptacle cela facilite l'installation.
The Timbren SES (Bump Stop) replacement for the 3rd Gen Sequoia is a simple and effetive solution to reduce vehicle sag when trailering heavy loads. You definately want to use the included spacer as the pics will show I still had 2 finger clearance above the axle to allow for OEM suspension travel. I pulled my 29ft boat back to back with / without the Timbren bump stops for a ride quality test. Without the bump stops, my 2024 Sequoia rear end was crushed, resulting in a rough ride and poor handling characteristics. With the Timbern bump stops, the rear sag was reduced signifincantly, and the vehicle drove much better. YES, you will feel and occasional bottom out feeling on abrupt G-out dips... But it is no worse than without the Timberns as the stock springs were crushed. My daily drive feels exactly the same as I have the perfect gap between the Timbren bump stop and the axle allowing the OEM suspension to float over road surface without engaging the bump stops. VERDICT: Time will tell with varied passenger loads, speeds, road surface bumps etc., but my initial impression is 7 out of 10. Ultimately, I would prefer air bags, and may install them along with the Timbrens whih I can swap back to the oem bump stop in less than 15 minutes. NOTE: I was able to install the Timbren bump stops without going under the Sequoia. I simply raised the vehicle frame aprox. 4" withoug picking up the rear tire. This gave me adequate room to reach in over the tire and remove the 3 12MM bolts holding the OEM bump stop in place with a 3/8" ratchet and a 4" extension. Then, I put the Timbren bump stop in place and lightly threaded the upper bolt to hold in place. After installing the two lower bolts and smart torquing, then you tighten the top bolt. This allows the bracket to seat against the frame fully as the top bolt hole is slotted to allow movement druing install. Pics will show spacers installed above the bump stops, Installed bump stops unloaded with 2 finger gap, spacers loaded with 750 lbs of tongue weight, and lastly, will show Sequoia stance while loaded. NOTE: The last picture will show my Sequoia loaded WITHOUT the Timbren SES (Bump Stops) and the vehicle is sagging heavily.
The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer
Installation was easy and straightforward. Haven’t towed with them yet, but the unloaded ride has not at all been negatively affected. In fact unless you hit a big bump you shouldn’t know they are there but they seem to improve handling around turns when there is a shift to either side in the back. It a HD truck so there is some expectation it’s gonna ride like a covered wagon at times. I added these in conjunction with new Billstein shocks and I’m hopeful all that aggravating bouncing or porpoising my fifth wheel does on bad roads and bridge transitions will significantly improve. etrailer was fast with shipping and follow up. I’ll update after towing.
Definitely a must have when towing..stiff without a load but night and day difference while towing my travel trailer, better traction, steering and braking. Easy quick install..only issue I had was with the long bolts they sent with the spacer kit (optional for lift) the bolt diameter was too wide to fit through the holes on the bracket..but a trip to the local hardware store took care of that.
Pros: Cheaper and easier to install than airbags, do the job when load is enough to compress the shock, with added weight or towing, then it stiffens the rear very nicely.
Cons: Doesn't do anything until there is 2-3cm of compressed shock. It sits above the contact point, doesn't touch. Under normal driving, there is no benefit/improved stiffness/anti sway in rear or a leveling of the factory rear sag in a 2022 or newer Toyota Tundra.
If had it to do over, would have put some kind of spacer in between product and upper included bracket, the supplied bolt is long enough to accommodate, to eliminate the gap, and lift the rear 1-2 cm. Should do it anyway, maybe when swapping to summer wheels next month.

I contacted the manufacturer about this and they believe it is odd and it sounds like the gap between their product and the axle may have the wrong gap. If you would like to look into it further, I will email you information on how to contact Timbren.
