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 Suspension Enhancement Compared to the Competition
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. Becomes more rigid as more weight is added for great performance when you're hauling a heavy load.by: Jesse03/20/2024
Pros: Cheaper and easier to install than airbags, do the job when load is enough to compress the shock, with added weight or towing, then it stiffens the rear very nicely.
Cons: Doesn't do anything until there is 2-3cm of compressed shock. It sits above the contact point, doesn't touch. Under normal driving, there is no benefit/improved stiffness/anti sway in rear or a leveling of the factory rear sag in a 2022 or newer Toyota Tundra.
If had it to do over, would have put some kind of spacer in between product and upper included bracket, the supplied bolt is long enough to accommodate, to eliminate the gap, and lift the rear 1-2 cm. Should do it anyway, maybe when swapping to summer wheels next month.

The TIMBREN SES was the best solution for my problem! They offer a progressive amount of spring support that was exactly what I needed when towing. They are maintenance/adjustment free and do not affect ride quality when I am not towing. Additionally, the support of the SES has taken a good amount of stress off of my E2 WDH. When under load, the SES makes my 1/2-ton Tundra ride/feel more like a 3/4-ton truck. I could not be happier, and I would highly recommend this system over airbags on 1/2-ton trucks.

I recently purchased a 2024 tundra hybrid platinum. With this being the luxury addition the rear suspension is lacking when in comes to towing when I would hook to my 7x16 enclosed trailer my truck really saved.
I purchased and installed the timbren ses stops and no more sag. The ride of my truck remains smooth when unloaded and the timbrens also stopef the side to side rocking. Will post another after I tow a few times.

You sent me the 2 right ones, they have to be more careful, I wasted a lot of time, when you send me the left one I'll change the review!

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.

I see that the springs have been returned and honestly this is something that can happen with this spring. While it is a well made product, the stiffness of the rubber does not allow for a lot of give. So am empty truck will be rougher. I say for your 2024 Toyota Tundra to give the Hellwig EZ-990 Helper Springs part # HE49XR a look as long as the Tundra has leaf springs that are not composite leaf springs. They have a 2000 pound load leveling capacity. They are adjustable and have a bolt on design.

I install these to eliminate the sag when I hook up my cargo trailer. Some people say The back end bounces when empty. I haven't had that problem, if anything the ride seems better. I don't get that dribble effect going over close bumps as bad as before I installed the timbrens. I installed them on a 2022 toyota tundra.

Great product good price exactly what we expected and instructions made for ease of a inatalation.
by: Jason03/16/2023
This is NOT a substitute for airbags. My truck is a 2022 Tundra and I let them know that my truck is lifted 3” and Timbren claims the kit works for that situation. That’s simply untrue as my truck sagged 2” with a 500 lb snowmobile in the back. Same issue as before Timbren were installed. THEN Timbren sent me a 2” spacer. The truck still sagged 1” in the rear and then the ride was bouncy and just very lackluster. DO NOT buy these as an airbag replacement. They are simply bump stop extensions and you’ll be riding on bump stops at full load. Not cool. And on top of that Timbren even told me my truck would be bouncy and uncomfortable while off roading. This was not mentioned to me by Etrailer and it’s a complete dealbreaker. Oh on top of all this, the kit reduces my rear suspension travel by having the steel 2” spacer. Please, someone tell me if I’m wrong or missing something here but I’d rather pay triple and get a real solution like Firestones or another brand of airbags.

If you are using these for daily heavy duty use, then they should work perfect. However, if you are only occasionally pulling heavy duty trailers, we do recommend some airbags instead.

I’m hoping that it will help as much as all the things I’ve researched say it will but o don’t understand how I’m supposed to install it if in the directions it shows three bolts washers and nuts in each oh the the bracket holes plus mounting the rubber to the bracket with another bolt washer and nut when one two bolts washers and nuts total were provided. I am short six bolts washers and nuts to mount them on my vehicle.

For this system you will re-use the hardware that you remove when taking off the original vehicle bump stops. When removing the hardware, you will want to use a penetrating fluid first to make it easier to remove them.

However, I would not count on them for off-road use. I'm afraid they would not last and rip off of the end plates. It also would not be covered under their warranty if they were damaged off-roading. Your best option would be to go with the Timbren # T45MR. You will also need to add in spacers # TA25723-90AD00 or # TA25722-90F00. There should be a 1/2" - 1-1/2" gap in there.

If you had a camper on the bed, or had the rear end maxed out all the time, then I'd recommend the Severe Duty Kit # T65MR, but I doubt you need that. If you used it and didn't actually need that much support, then your truck would suffer from a rough ride all the time.

As for the Timbren # T45MR, I would consider how frequently you're towing or hauling before adding them. If you're towing this trailer all the time they are an alright option. If not, your unloaded ride quality will likely leave you wishing you hadn't added them to the truck. I...
