Specs:
When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.
The Timbren system has a vehicle-specific bracket that will be 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 one inch 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 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 provides increased resistance, stiffening the suspension and keeping the vehicle level.
Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 hauling off-center loads.
Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping 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 passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.
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 as the rubber springs work to prevent bottoming out on rough roads.
Compared to the competition:
Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

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.Having purchased a cargo trailer, I thought it might be wise to beef-up the rear suspension on my 2000 Tacoma. I found the Timbrens on etrailer, and it sounded like they might work well, so I purchased a set and installed them. According to the instructions, there should be about a 1/2" gap between the top of the springs, and contact with the bottom of the Timbren - unless you have a CAP on the truck! The gap pretty much evaporated because of the fiberglass Leer cap. So, I'm getting contact a lot of the time. Result is, my ride has become stiffer than I'm used to, but not so much that it bothers me. Like my wife said, " It's a truck! Hello!!" (OK, I'm satisfied with the product.)

I’m a Farrier, I carry a full workshop in the bed of my truck 24/7. I drive a 2001 Toyota Tacoma 4x4. After a couple months I redid the entire front and rear suspension and added heavy duty rear leafs. After about a year of driving and also adding more tools the truck began to sag a little bit. Ofcourse, the first thing anyone suggested was “airbags” but they didn’t know the use of the truck or where the truck goes from day to day. Being a Farrier, I travel on everything from paved freeways to down and dirty “4lo” back roads. I needed a maintenance and care free system that would allow for over extension and hold the extra weight of my tools and sometimes even a trailer. I did a ton of research and even talked to the Technician Staff at each company. I ultimately decided to go with Timbren SES Kit. It’s easy to install, maintenance free, free floating, and has the best warranty in it’s category. Since I have a custom setup (Ubolt Flip Kit from AllProOffroad) I had to design and build some landing pads to allow for an “interference free” contact with my system. After the first day of working, I am COMPLETELY satisfied with its performance and how my truck feels and drives.
As for ”Etrailer” I am very happy with all the information and excellent customer service. I received my parts 2 days before it’s orignal date which makes me super Happy!
I own a 2002 Toyota Tacoma crew cab, with a leer topper, I work in construction and carry my tools all of the time.
I’m very pleased with it and it’s been the best I ever had.
the bolt should be galvanized or stainless, the bolt is getting a bit of rust after one year.
Even then I would recommend this.
Thanks
This worked great and was easy to install. No impact to driving quality when unloaded. Does make a nice improvement to ride quality when loaded and the rear end of the truck does not sag under the load.
One issue is the bolts were about 1/2" too short, the nylock washer barely makes it onto the threads.
The overall product design and usage has been excellent. Carrying heavy loads is easy and my '01 Tacoma handles bumps and ranch roads much better loaded down. I'm running a 3-in lift so there is no contact from the rubber springs and unless I'm heavily loaded, works great for off-roading. I had to grind the corner off one of the mounting plates to make room for my brake line,and get creative about starting the nuts inside the rubber springs but it was well worth it.
Installed these on my 2004 Tacoma 4 door, 4WD. They were great with a trailer on back and handled the load great. Without the load of a trailer it is like riding a hard tail Harley. In the process finding something different to help the sagging springs.
Mike L - 11/28/2018This is a great product for when i am towing. It really beefs up the rear suspension and prevents the proverbial Tacoma sag. However, since it is not easily removable, it stays in place all the time. It makes the ride rough, and you can feel every little bump. No give. I knew this going in, but I think air shocks would have been a better decision. Overall happy with the performance.
This product has worked extremely well. Ride is a little rougher but very stable when towing our teardrop and kit or hauling tools to worksite. I do have experience with airbags but feel a more stable ride in corners, etc with this product
Haven't installed yet but the customer service and delivery was excellent so far. I called Timbren prior to ordering to double check I was selecting the correct product for my 2wd Tacoma, which actually needs the 4wd drive version the the Timbren bumpstops bc of the TRD model. Timbren immediately picked up the phone and quickly assisted me.
Very straight forward. Initially I was given a date that was a little farther out than I had planned. Was offered a similar product that could be shipped immediately. I appreciate that attitude. Offer a solution to the problem. I chose to wait. Product showed up as they said it would.
Excellent service.
These are fantastic. All Timbren Suspension Products I have used work great and noticeably improve handling and performance.
Great product, great service. No more blinding oncoming traffic when I’m loaded or pulling my boat. Truck stays nice and level
Timely shipping! Project is completed, Thanks.
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
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!
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
The hardest part was the de-installation of the factory bump stop. Installation of the Timbren’s was simple and easy.
My truck is 2008 F250 V10 Crew Cab 4x4 with factory overload springs. I have a B&W fifth wheel & gooseneck hitch installed. I did notice the difference in towing my 34’ fifth wheel trailer. The ride and handling was improved. I would recommend them.
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
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.
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
They may be a great product but they did not work on my 22 f350. Even with the spacers provided they would not make contact with the trucks axle even with a heavy slide in camper. If I am going to keep them I’ll have to make welding modifications to extend the bracket so it will work on my truck model pictures with and without the camper loaded.
I would like to update my review to say that Timbren came through and made my application work by sending me the right parts so my truck doesn’t squat and it handles my truck camper much better. Timbren has great customer service
Brooke M - 12/29/2022Review from a similar Timbren Aeon Spring System in Vehicle Suspension
I installed Timbren on front and rear of Georgetown motorhome. The install was easy and the improvement in overall handling was noticeable. No more bottoming out on bad roads, and a reduction in sway or lean in and out of turns. Worth the money, especially in conjunction with my other bolt on upgrades. Safety steer, Rear sway bar, and Rear trac bar
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
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.
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
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!
Review from a similar Timbren Aeon Spring System in Vehicle Suspension
The Timbren rear suspension enhancement system helped with the truck swaying side to side when the slide in camper is on the truck.
The photos show right and left rear with Timbren’s installed (2 photos), with slide in camper on the truck (2 photos) and when the camper was removed (2photos).

One of the timbrens appeared to be installed once and removed. Box said it was 2018 on it.
