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.

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.)

A year later and 5,304 miles pulling the trailer, I think the Timbrens are a good investment. With a typical pull of 2,555 lbs of trailer and load, and approximately 300 lbs of tongue weight, Im finding the truck actually rides better than it does with no load. And, theres no maintenance whatsoever!
Just what the truck asked for...
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!
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.
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
Made the ride horrible. Tons of vibrations when weight on truck
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.

The Timbren Aeon springs are meant to be used on a suspension thats in good repair. Normally, the vehicles ride will be completely normal until the rear suspension is loaded either from cargo or by the tongue weight of a trailer, at which time the suspension will compress far enough that the Timbren springs come into play.
I can always count on etrailer and Timbren for products I can count on, delivered on time!
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.
This 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
These are fantastic. All Timbren Suspension Products I have used work great and noticeably improve handling and performance.
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.
Great product, great service. No more blinding oncoming traffic when I’m loaded or pulling my boat. Truck stays nice and level
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.
Timely shipping! Project is completed, Thanks.
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.
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.
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.
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.
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.

Keep in mind that the gap Timbren refers will diminish as the springs wear. Since the truck is a 2000, it probably has some miles on it and if it has hauled heavy loads in the bed or has pulled a trailer, then the leaf springs may just be worn.
