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.

I have purchased two sets of timbren rear suspension products for my 04 gmc and 21 gmc both set preformed as promised don't have o4 any longer but last I heard still doing there job. Have ordered several products from e-trailer great customer service and ease of ordering. Very satisfied with tibren and e-trailer would recommend to anyone.
Just received the Timbren TGMRCK35S. It was a very simple install. I didn't even need to jack the truck up or take the tires off. This product seemed high in price for what you get. The truck always squatted low and bottomed out on bumps whole pulling my 5th wheel. I haven't really had these long enough to make a fair assumption on them. I would say check back with me at the end of the summer. By then I will have traveled great distances pulling my 5th wheel. Definitely seems as though they will work for what I has purchased them to do.
The package arrived today at 12:30pm and we’re on my truck by 2:00pm and I’m slow. I’m exited to see how they perform with a load on my pickup
Really great service, your staff were helpful in identifying the product I needed for my vehicle, processed the order quickly, and within hours my order was shipped. Thanks folks, that is the way I like to do business.

This product has been on my truck for a year now, and with more than dozen long trips with truck fully loaded, these cushions have keep my truck level and well clear of the frame. Id still give them 5 Stars after a year of use.
Awesome product awesome service awesome delivery just simply awesome
Easy to install. Takes out the "harshness" over poor roads.
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 product came very fast. I already installed it the same day on my 2009 Dodge Ram pickup. It looks like it should do a fantastic job. I'll know better when I hitch up my travel trailer.
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.
I bought the timbren SES 121474110. I am not really satisfied with how these helped my trucks towing stance. The truck tows the same. I carry an in bed tank with 50 gallons of fuel in addition to the 35 gallon fuel tank from factory. The truck rides the timbrens the whole time. Thats okay, my problem is that the truck squats the same amount with these when I hook up my car trailer. The truck still goes straight down to the load leaves (pretty heavily squatted) the same as before. Did I get a light duty version? dont feel these meet the 6,000 Ibs capaticy as advertized. I think I should have gotten air bags. The product was well made. so they still get 2 stars. Just not what I thought it should have been.
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.
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..
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.
Out of the box fit !!
Only issue I had was keeping the wedge from moving during installation
These work really well with the coil springs on my 22 Tundra, I'm really impressed with how strong these springs are, on purpose I hooked up to a trailer I no business hooking up just to see how much squat there would be, once they made contact there was no squat at all! I put them to the test by hauling my 9400lb travel trailer from Arizona to Iowa. They worked well with my weight distribution hitch for effortless towing. Very easy to install. I save time by not having to adjust air pressures after hooking up to a trailer, hook up and go! I was on the fence with air suspension and the timbrens, George from etrailer listened to my situation and recommended that these would be the best fit, he didn't steer me wrong.
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.
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.
After successfully using air shocks with on board compressor on our 2001 F250 for years, I almost automatically put the same setup on our new 2022 F250. We tow an 11k lbs travel trailer. Then I read reviews on Timbren Suspension Solution & thought, worse case I’ll end up with both solutions. After spending 20 minutes installing Timbren and towing the trailer a few miles, it became obvious I didn’t need air shocks, or anything else. The truck & trailer drive as one. Our rig is level and rides great. When the trailer is unhitched, the Timbren’s aren’t engaged - just a normal F250 ride.
The Timbren rear suspension bump stops are the best by far. I installed this unit on a 3rd gen Toyota Tacoma which became an essential item for safety towing purposes.
The main reason for purchasing this product was for aided support for towing. This is essential for those who tow boats, tear drop trailers or medium sized campers.
The stock bump stops are relatively small in size which is standard for other vehicle manufacturers however Timbren's bump stop are made with such high quality material and craftsmanship.
This also helps in preventing in stressing the front suspension from becoming raised which can affect your steering when your towing. The Timbren bump stops also helps in preventing your rear suspension from the "sagging effect" which can cause stress to your tires.
I recommend that when you install the bumps stops, check the lugs every quarter or depending on frequent you tow, to include tightening the lugs with a torque wrench to ensure it's torue specification(s).
This product has given me peace of mind when traveling long distances and when camping off the grid. Timbren also has good customer support service however etrailer has paramount customer service as well.
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.
Caution,these parts did not fit my 2008 Suburban 1500 as advertised. Also FYI, Amazon also says they will fit. After some alterations I got them to finally seat. Tha original bump stops have a groove cut into them about a 1/2" from the top to accept 6 pertrusions that are stamped in the bump stop cup. After several attempts to press the Timbrens into place they wanted to pop out or were very easily removed with little pressure.I ended up cutting in 6 notches with a utility knife. Photos attached. I used markings on the old bump stops to determine spacing. I marked the Timbren with chalk to illustrate approximately where I notched them.Caution, cutting hard rubber with a utility knife is dangerous if you are not used to using a utility knife. I believe Timbren makes a spacer with a groove cut in them. That would make installation a lot easier. I cannot fault etrailer because they probably are following Timbren specks. Also I am not sure all Suburbans of this era have the same bump stop cup. I would recommend checking your old bump stops before ordering. Hope this helps.
Worthwhile investment. Easy and simple install. Adds stability to keep RV from wanting to tip over. Same as adding a torsion bar. Needed to jack up the body, to install and after installation, Timbrens are engaged with no clearance either on top or bottom. I would purchase again if needed.
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.
I just installed Timbrens in our 2024 Sequoia Capstone. It has 22" wheels so I was able to slide under the rear axel and swap out the factory parts without jacking or removing the the wheels. It took me about 20 minutes to do both sides. With no load I can fit almost two fingers between the axel and the bottom of the Timbren. I tow a 29' boat that has about 600-700 lbs of tounge weight. The Sequoia sits pretty level and rides great. I had a 2010 Sequoia before this one that I installed manual rear coil airbags that worked well. I like the Timbrens as there is no pumping every time I tow.

I have since removed this suspension enhancement system. It worked great took out the sag, prevented body roll, all it said it would do. I just could not get my 5th wheel to ride level with them because there was little to no squat. The front of the camper road high. I couldnt get it any lower with my hitch set up. More weight was thrust onto the rear axle on the 5th wheel and those two tires wore out quickly. I just dont know what caused it. Incorrect axles originally built on the camper, overloaded, or what. As I said, this system works great but I just never checked into why I had issues
