3,000-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.

3,000-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.Had to have it professionly installed.bolts were torqued to the max and access to the bolts was impossible to get clear line for wrenches, when completed ride is better and vehicle sits higher. service and delivery was great
Does a great job when towing a travel trailer. Really helps with windy conditions keeping the vehicle from dipping in rear with sway of trailer. Vehicle is much more stabile after the install.
Supports my power wheelchair and rack with no problems. Handling is the same with or without a rear load. Very easy to install, [online] video was great
The product works great on my Ford Flex

Working great, it’s a nice and tough product
Item is just as described, thank you etrailer for the how to video install for my Ford Explorer. Install took 1hr.
These were very easy to install, about 15 mins each. I have not been able to test them with a loaded trailer but they look like they will certainly help with back end sag.

Fantastic
Fits perfect on our Ford Flex's. Half the price compared to the shop.
pretty ez install....fast delivery
The job took about 1 hour all went wel l.
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.
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.
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.
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
I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.
Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!
The Timbren rear bump stops for 2020 Suburban were great quality and fit perfectly in the replacement of the original ones with no problems. The old ones pulled right out by hand with no hassle. When I installed the new ones I put 2x4 blocks that I cut underneath the bump stops. Then hooked up the 6,400 lbs travel trailer with about 750 lbs of tongue weight on it and they pressed right into place. The Suburban was more stable because it had less swaying while towing. I also gained about 1 inche more in the fender gap which means less rearend saging.
Despite reading about the popularity in using Timbren’s for suspension modifications to assist in ride quality when loading up the Odyssey, I haven’t found many reviews about the Timbren’s for 4th gen Odyssey though there are a ton of positive reviews for the 5th gen Odyssey on the forums and internet.
I went with Timbren’s due to the “set it and forget it” lack of maintenance. I do notice a more stable ride even unloaded at highway speeds. There’s less sway in on/off-ramps and big sweepers. Not a huge change, but warmly noticeable. About the same quality of change one might experience from buying a brand new set of tires vs. not dangerously worn down tread. Where it really shines is under load/heavy cargo.
Before Pic (unloaded mulch); After Pic (loaded) - definitely not as much squat as with the prior OEM bump stops! Comfortable ride with less jostling/sway and haven’t bottomed out the springs over rough road. I’m impressed! Install was fairly easy, about 45 min per side taking my time, cleaning removed parts. One year later, I haven’t had any issues, and I feel very comfortable loading the minivan with all our gear/stuff.
I do not tow.
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.
ordered over the phone and got a very nice lady that was very helpful. was feeling like crap so took a few days to open box up and found out only half was there no bolts only one top mounting piece and only one rubber spring part. but i got two big rubber washer things
I have a ram 5500 rollback towtruck it works great no more draging or saggin even with heavy loads has the truck level
I was back and forth between Timbren SES and airbags. Everyone in forums were very biased toward air bags and very opinionated on the Timbren SES. Yet I could find one instance in which someone tried the Timbrens, were dissatisfied and then switched to air bags. I called etrailer, Jamie recommended this product to me for my application. Installation on a 20-year-old truck had me nervous, I live in the Midwest and have a lot of salt. Installation was a breeze, and I have a B&W 5th Wheel Hitch (turnover gooseneck ball). This made the install a bit more challenging simply because I had a large bolt through the frame directly above my bump stop nut. If you do this install with the B&W Hitch, get a set of gear wrenches, or borrow a buddies 15mm and 9/16 wrenches. You need the 15mm to remove the factory nut and the 9/16 to install the Timbrens. I sprayed wd40 two nights in a row prior to installation to make sure I had good penetration of oil - I didn't break a bolt or a knuckle. I recommend installing the Timbren spring to the mounting plate, then install the mounting plate with Timbren to the truck. I didn’t need to remove my wheels or my spare, I jacked up the back under the hitch, used jack stands and let the weight of the axle separate the rear end from the truck giving ample room for the installation. After installation, I checked the clearance of the TImbren from the axle and had 1 inch of clearance. I installed my 1200-pound pickup camper and the springs just started touching the axle. I have a 21-foot fiberglass boat and seen about a 1/4-inch drop after I connected it to my truck. These things work and best part is – no maintenance and no danger of shifting weight if an airbag lost pressure or was punctured/damaged. I hunt with this vehicle and drive through thick brush and timber, I feel airbags wouldn’t hold up with the abuse I put my truck through. The Timbren SES system took the squat out of my truck and made the drop from the connection of my heavy boat hardly noticeable. Thank you etrailer, great experience as usual!
It does a good job of dampening the impact of a suspension bottoming out in a fully loaded vehicle. We have owned our 2005 MPV LX sine new and I have 3 children plus a sister-in-law who goes on camping trips with us. Through the years, I noticed that when fully loaded, the van started hitting the bump stops more often and this is felt as a violent thump when going over bumps or dips in the road. This was getting me worried that the springs and shocks were worn out so I had my mechanic replace both of these because on numerous camping trips, this never happened before. It only partially solved the problem. Then it dawned on me- my kids are now all grown up/heavier. I just wasted $2K on new springs/shocks. I tried rubber coil spring spacers and upgraded my Bump stops to sturdier polyurethane units to replace the foam rubber original ones but these did not help at all. I considered the Air spring inserts but was worried about their complexity, durability and difficulty of installation since I wanted a DIY solution. The Timbrens did a good job of softening the impacts such that my rear passengers immediately noticed the improvement. The suspension still bottoms out but the impact is now soft and it does not affect the normal driving dynamics of the vehicle when not fully loaded. Installation was so easy that I made my two teenage sons do each side to teach them a few life skills. I give the product a thumbs up. The only downside is they are very expensive for what they are made of- simple rubber, bolts and washers. To compare, I could buy two new tires for the price of this pair of SES Buffers. Save your money and try these before replacing the rear springs/Shock absorbers.
Works perfectly as expected. Took the extra bounce out of the rear-end when towing out 5th wheel.
It also keeps the tow vehicle level when fully loaded with 5er and all our gear.
