6,000-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.

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.
Alright it’s been a year. We have hauled our travel trailer about 10 times since and the ride is great. The side to side lean is non existent. I also got the springs for the front. The ride is a little rough when I’m not towing but that was expected. Overall I’m super happy.
It's a perfect solution for my trailer setup. The best part is I don't really feel any hard bouncing and there are still room left for rear suspension. Tundra with a trailer about 700 lb tongue weight.
Have not had a chance to install it yet but everything showed up as expected and looks like a great fit. I have a 2017 Tundra SR5 TRD Off Road, I could fit a 1/2 inch spacer in but don't load my truck down every day so the 1+ inch gap before the stops seems perfect.
Just what I needed. Easy to instal, stops the drop, and levels out my 2021 Tundra while towing. I highly recommend this product as a cheaper alternative to airbags.
Bought these for my new 2018 Toyota Tundra. On my previous 2010 Tundra, I had installed helper springs and decided to try Timbren's this time around. I bought 1/2" spacers, since I did not want the truck to sag too much. Not sure if you can see in the pictures, but with the 1/2" spacers, the Timbren's come into contact approximately 1/2" to 3/4". They can be a bit rough and bouncy once they come into contact, but no rougher or uncomfortable than with helper springs. Over all I am very happy with how they perform. The installation was very easy. Took me about 1/2 to 3/4 of an hour. All you need is a 24" breaker bar, a ratchet wrench, and a 19mm deep socket. Unloosen the nuts enough to remove the existing bump stop and replace with the Timbren's. That's all it takes!
I just wanted you to know that prior to my installation, this Coachman with a hitch weight of 700+ pounds would push the rear down so much that there was barely daylight between the tire and the wheel well...but look at us now. This '04 Titan with 189,000 miles and original suspension is riding high. Your product helped me get the bed level and has reduced the sway on the trailer so much that it is hardly noticeable. I am very happy with my purchase, your follow-up and the results.
I've had these on my '16 Tacoma for a year now. When the truck bed is empty, the ride is harsher than before, but not intolerable. When I'm loaded up for hunting (lots of heavy gear, maybe an elk, plus towing a pop-up camper), it's perfect--never bottoms out like it used to. I keep 120 lbs. of sand back there all winter for added traction in the snow, and that helps to smooth out the ride a bit. This photo with sagging rear was BEFORE the Timbrens--now it rides level.
These bump stops are great and very easy to install. They help keep my 2019 Tacoma leveled when towing my 5,000lbs trailer. I’m very happy and recommend them if you are planning to tow a trailer with your Tacoma. My only complaint is that sometimes when driving on old or uneven roads, they will make the ride very bumpy as if you had a sports suspension.
These are a must on a Toyota Tacoma with a canopy on or if your carrying regular heavy work equipment.
20 min install tops. Took more time retorquing the nuts after loading. Couple tips: only remove the two rear nuts on each u bolt to slip out the old bump stop to replace with the timbren. Go ahead and spray those nuts with pb blaster or wd 40 to help ease removal. I used a breaker bar so it was no problem. I would suggest that once you have the timbrens in place, I would jack up the rear under the receiver hitch (I used wood blocks) and slip your socket and extension back into the bump stop to retorque the 17mm bolt. I also went ahead and retorqed the nuts once I hooked up trailer. As far as towing now, wow what a difference. Virtually eliminated all front axle hop from road dips making for a much more confident and stable ride. 26' coach, 4900# dry. Pics are unloaded and then loaded.
Easy installation and certainly sits more level with our travel trailer hooked up.
This is an amazing product. Took about 30 minutes total to install on my Toyota Tundra. That includes setting up and clean up. I pull a 20 foot flat bed trailer and a 30 foot travel trailer. This product really helps me when I do encounter bumps and uneven lanes. Helps keep my rig secure on the road and doesn’t interfere with normal everyday ride. I would definitely buy this product again and I most certainly would purchase from etrailer again. Great company, support and prices!
They definitely support and did lift my 2014 toyota tundra up about 1.5 inches.
This application with my weight has trunk riding on the cushions all the time.
That has teavel and bounce issues that do make some driving situations interesting.
I may go ahead and replace with airbags but for now support things well!
Just finished installing the TTORTUN4 Suspension kit on my Tundra. It took me, with limited mechanical ability, about an hour to install and was a simple and easy installation. My truck loaded with tools, a construction canopy, and heavy bed-slide sits up in the back like its unloaded, rides great, and handles so much better! I'm super pleased! Thanks so much!
The installation went well. My Ubolts were fairly new on my truck so the nuts loosened without any problems. I would recommend spraying the ubolt nuts with penetrant prior to installing this product on rusty or slightly rusty vehicles to avoid breaking the ubolt. I am sure this product will be helpful on my 1/2 ton pickup. I installed a pair on my previous 2500hd sierra and were in great condition after 8 years of towing and hauling wood, trailers, campers, etc. This is a great product to use bs. Adding a helper spring. Much softer ride until the truck is loaded. No rear rake is added either.
UPS lost the box, but one e-mail to etrailer and another was on its way. Installed easily and is performing just as I'd hoped. Truck is more level and the ride is a little stiffer so towing is much better.
These are great! Dont change the ride at all when not in use and make towing my 7000lbs trailer so much more comfortable! Tow with confidence. Easy install took ten minutes with my buddy's lift. Could have been done easily on the ground too. Improves handling and ride when towing
Modem skill required for installation , fit was perfect ,great help on maintaining vehicle handling with my car trailer on while traveling highway . I would recommend these to any hauling a trailer or frequent truck loads . only

My thoughts remain the same on this product. Great help while towing loaded car trailer ,
The Timbren system has helped greatly while pulling my 5600 LB RV. It aids with the sag and my truck does not look like a "low-rider" while hauling the RV. It also appears to help with stability. I also haul a pontoon boat with my truck. At times with the lighter load it appears to be a little stiff; however I can live with that alright. I don't have to worry about airing it up as like other systems due to the spacing between the suspension and the frame. I would recommend this product to those who haul boats, RV's, or commercial loads. Very happy that I decided to purchase and install this product. Lastly, I did not install the system myself, but observed my mechanic friend as he helped out. It appeared that it is relatively simple to install.
Super easy install, took less then 30 min. Great for towing our small trailer and hauling bikes.
Easy installation great product
Product was shipped fast . Only took me 15 minutes to install. Can’t wait to try it out. Should make for easier towing. Thanks etrailer
A great upgrade. I would recommend if anyone is towing regularly or heavy.
Great product and very easy to install. I haven’t loaded the truck yet but I’m sure it will do just fine. Here’s a before and after, total install time 30 minutes.

The timbren system is the way to go. The increased stability while towing is great. One of the greatest benefits of this system is that you enjoy a totally factory ride while unloaded and get instant stability when you hook up a trailer or load your pickup bed. Even when loaded or towing the ride is much better than my past vehicles that I added a leaf spring to. The add a leafs caused a harsher ride at all times where the timbren suspension does not. I highly suggest them.
