When you’re towing a trailer or hauling gear, rear-end sag can throw off your steering and braking. The Timbren Suspension Enhancement System adds up to 3,600 lbs of load-leveling support to help keep your vehicle level and stable. The hollow rubber springs sit above the rear axle to assist your factory suspension, reducing squat and improving overall handling when the weight’s on.
Bumpy roads and uneven terrain don’t have to beat you up. Timbren’s Aeon hollow rubber springs compress progressively—the more weight they take, the firmer they get. Light loads feel cushioned and smooth, while heavier loads stay firm and controlled. They absorb road shock and prevent bottoming out, helping your suspension last longer while keeping every drive comfortable and steady.
Each spring works independently to support its side of the vehicle. That means when crosswinds hit or you corner hard, body roll is reduced and handling feels more planted. This independent action also helps balance off-center loads, keeping both sides steady even if one is carrying more weight than the other.
Installing suspension support shouldn’t turn into a full weekend project. The Timbren system includes two hollow rubber springs, custom-fit brackets, and hardware that bolt directly onto the frame—no drilling required. With a straightforward design and no airlines or compressors to route, you can get reliable load support without extra adjustments or maintenance.

installs easy and quick
Good product and relatively easy to ins tall
Worked fine. Sold truck
the product was easy putting on and works great
Exact fit and fast shipping!
Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.
Great customer service, communication was on point. When I had concerns about the parts not getting to me in time for a big camping trip, the parts was rushed right away. I will forsure order again from trailer.
I installed them but have not used them yet
Noticeable improvement in driving stability under load & more importantly during towing. While empty, the bottoming out can be abrupt & rough with the change in clearance but not to the point of being too interfering.
Install was a breeze. I would make one suggestion… don’t reuse your U-bolts after you loosen them. When they are tightened they stretch. I had a shop make new ones for me for $xx and about 15 minutes of my time. As far as the timbrens go… I’ve purchased them before for trucks I’ve had in the past. They work great, that’s why I keep using them on my vehicles. Zero maintenance, just put them in and forget about it. I’ll be buying again for next truck.
These helped my suspension for loading my side by side into the back of my truck
The Suspension enhancements are still working great. I tow a 5000 lbs RV and there is no lowering of suspension with these. The ride is very stable with no sagging.
Timbren Suspension Enhancement System - Rear Axle Item # TGMRCCA
I installed these on my 2016 Colorado Diesel. The total time it took me was under a half hour on a lift with a jack under the axel. I pull a 5500 lb trailer from CT. to Fl. I won't know how much of an improvement it will make until next week. The tongue is 690lb and I loose about 5 inches when the trailer is connected, hoping this will reduce the sag and improve the ride.
These really work good for keeping your vehicle level under load, the problem is, they need to be closer to the body when not under a load. Once you get down to them the suspension travel stops. Would feel better if they were taller and had a little more give, more progressive. I have since removed them. Had a set for a 31ft c class E450 and they worked fantastic. Not so much on a light truck.
The product was shipped in an expeditious manner in spite of the mid week holiday.
The instructions indicated less than two hours for installation and it really only took just over one hour. The instructions were spot on as to how to install the product.

Prior to installing the Timbren kit, loading my golf cart caused the truck to squat some three to four inches. Now, the same load causes about a 1 inch lower stance. The loaded truck handles as if there was nothing in the bed.
I wasted time with add a leaf springs and wasn't happy with the results. Opted to try the Timbren's and they worked great. Super easy installation and what I really liked was the ability to adjust the height with shims to get the height to wear I needed. Great service from "etrailer", kept me informed of shipping and the price was great! Thank You, Randy!
Easy install

I'm glad the install went well for you, Andrew. Good job!!!
I had made purchases from etrailer in the past and have always been satisfied with the service and products purchased. During this transaction I purchased Tembren bump stops for my 2019 Chevy Colorado. They dont affect the ride of my truck until I put it undet a load. Then they give me better handling of the truck and less weight taken off of my steering. It was quite an easy install, and they work great! I feel the price could have been a little better, however overall I am very satisfied compared to what it would have cost to install air shocks. Thanks etrailer, another satisfied customer!

Since purchasing the bump stops from E Trailer I have been hauling a 5000 lb. Travel trailer for about a year. I am very pleased with the ride of the truck under a load. The Tembren bump stops improved things significantly. Thanks E Trailer! Another purchase made from you and a very satisfied customer.
I ordered the Trimbren suspension stop bumps in stead of air bags because of the excellent reviews, easy of installation and cost. They arrived yesterday and I installed them in about an hour. I torqued the u bolts to factory specs and noticed my original number stops had loosened a little so they were not difficult to install outside of cleaning the dirt off prior to reinstalling. After installation I have 1.5 inches of clearance which is what I was hoping for—original ride in my Canyon is unchanged but suspension enhancement will take affect when I load my mid size truck with a 5000 lb travel trailer. Can’t tell more until I load it but I am extremely happy so far. This order delivered on schedule and in great shape—really like the tracking notifications from etrailer. Thank you.

I was pleased that the Trimbren product kept my Canyon level with travel trailer. But even though I was payload legal and my Canyon diesel could handle the trailer from a suspension stand point I never felt comfortable towing. I knew I was close to the payload capacity and on certain road types a rhythmic bounce would occur forcing me to slow well below speed limits. It is true that you can not increase payload limits by adding air bags or Trimbrens they just help level the vehicle. I ended up trading the Canyon for a HD Ram 2500 diesel and changed my world!
Instructions where adequate but could have included the torque specification for the u-bolts.
I have the timbren enhancement system on my 2020 canyon. I haul a trailer with Ranger that I pull about 250 miles to hunting camp. It tows great!
Installation on my 2023 GMC Canyon was very simple. 1 5/8 clearance between the frame and new bump stops.
Purchased these for my 2018 Colorado D-Max. Installed these in about one hour. Needed to move one DEF line at the brake line bracket slightly.
My boat caused the rear to sag quite a bit. After installing these, there is a huge difference in handling and ride height when towing. While it seems a bit harsher, the sag and sway are less noticeable. Since the frame is off these bumpers without a load, the unloaded ride is unchanged except on very bumpy roads.
This is my second set of Timbren SES to use; I have a set on a 2004 Ram 2500 and a set on a 2024 GMC Canyon. I’ve used other products in the past, but I prefer the Timbren System due to ease of installation, reliability and low cost. The Timbren System is foolproof and never fails.

Timbrens are great Brandon! What are you hauling that requires additional support?

Still think it is a great product...but without the bed load, the ride has proved to be a bit uncomfortable in such a light truck. I was on the fence about keeping them on so I removed them temporarily and realized how much of an impact it was on ride quality. They def help with a bed load or a trailering laod. The truck is fine trailering without them but with a 12-58 ton bed load, they certainly were a great help.
