  • No-Airline Simplicity: Bolts in place with no drilling or compressors for easy, maintenance-free use.

Features to know about

Stay Level When the Weight Shifts: 12,000-lb Rear Suspension Support

Heavy trailers or bed loads can make the rear of your truck sag and throw off steering and braking. The Timbren Rear Suspension Enhancement System adds up to 12,000 lbs of capacity with hollow rubber springs that sit above the axle to keep your ride level under load. The system works with your factory suspension to reduce squat and maintain a steady stance whether you’re towing or hauling heavy gear.

Smooth Out Rough Roads: Hollow Rubber Springs That Absorb Shock

Rough pavement and washboard roads can beat up your suspension. The Timbren system’s rubber springs act like cushions, taking the brunt of bumps and rough roads so your ride feels smoother. They absorb road shock and help prevent bottoming out, which also extends the life of your vehicle’s suspension components.

Keep Control Through Turns and Crosswinds: Independent Spring Action

When you swerve, turn sharply, or haul an uneven load, each Timbren spring works on its own to stabilize that side of the truck. This independent action helps cut down on body roll and sway so you stay in control through corners or crosswinds. The result is steadier handling and less trailer movement when the wind kicks up or a semi passes by.

Install It Once and Get to Work: Simple Bolt-On Design

Getting extra load support doesn’t have to be complicated. The included vehicle-specific brackets bolt onto the frame above the rear axle using existing mounting points—no drilling required. With the hardware provided, you can install it using basic tools and be ready to tow or haul with confidence in just an afternoon.

Video Transcript for Ultimate Overview of the Timbren Rear Suspension Enhancement System-TFRSDP

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Timbren Rear Suspension Enhancement System. This system is going to feature these hollow rubber springs that will replace your factory axle bump stops on the frame to help stabilize and level your vehicle. These will act as shock absorbers to help take the brunt of bumps and rough roads and help to keep your vehicle level. Now, when you think about suspension enhancement, most people are familiar with airbags and obviously these are not gonna be airbags. So, there's some benefits and some drawbacks to going with these over airbags.

The first benefit is gonna be the ease of install. So, with airbags, you're not only gonna have to install the airbags but you're also gonna have to run tubing to get those connections where you can air those up. These are going to be very simple to get installed. They are a custom fit with these brackets here. They do include installation instructions for you as well as the hardware that you're gonna need.

But these are specifically designed for your 2008 through 2010 Ford F-450 Super Duty. So, if you do have a F-450 Super Duty, very simple to get these installed. Basically, just remove your factory bump stops, put these in their place, and you're ready to go. Another major benefit of these over airbags is that they're not gonna require any maintenance. They're kind of a "set it and forget it" sort of solution.

So, with your airbags, you're gonna have to add air for heavier loads, take air out for your lighter loads, otherwise it's gonna ride too stiff or you're not gonna have enough support. These use a progressive design, so the leaf springing, these are going to allow your leaf spring ample movement and while they cushion light loads, that's not gonna affect your empty ride of your vehicle at all. But then, that progressive design is gonna provide the additional support needed. When you have your heavier loads, they become more rigid the more they're compressed, the more the weight is added. So, that's gonna help increase the stability while you're hauling heavy loads.

It's also gonna help reduce your vehicle sag, improve your suspension, handling, and safety. These do have a capacity of 12,000 pounds. Now, when you hear that, it's tempting to think that means it's gonna help increase your vehicle's weight carrying capacity by 12,000 pounds and that's not the case. There's no suspension enhancement system that I know of that increases your vehicle's weight carrying capacity. So, think of it less like a second set of hands that's helping you lift more weight. Think of it like a back brace. So, it's there to help your suspension, kind of take some of the strain off of it to help it last longer. So, these are gonna do a great job of helping to extend your vehicle's suspension life, to provide a little bit more comfort for your ride, and that sort of thing. Because we do have two independent springs here, they are going to work independently, side to side. So, it's gonna help compensate for your off-center load. So, if you do have a really heavy toolbox on the one side of your truck, or something along those lines, that spring is going to compress more and give it more rigidity and stability and then that other side is gonna be left to engage lightly to help compensate for swerving or turning corners and that sort of thing. It's gonna help reduce that body roll. These do come with a limited lifetime warranty and a satisfaction guarantee. So, if you we're to have any issues with them, you're more than welcome to reach out to us here at etrailer.com. But when you're comparing airbags to these, one of the downsides to these is that you don't get the custom-ability, don't get to customized them as much as you do with airbags. So, with airbags, you do have the ability to add more support for your heavier loads. So, again, with the maintenance, you'd have to do that with your airbags, where these, you don't have to. They're kind of a "set it and forget it", but you don't have the option to add more support with these. So, some people might prefer airbags for that reason, but overall I think these are gonna do a great job for you. They're gonna help absorb some of that impact to support your suspension, take some of that strain off of it, help it last longer, and make the ride much smoother for you. So, that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

12,000-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.

Received the Timbren SES kit in today's mail around 11:30AM, already installed on my 2024 F-150 pickup's rear differential before 3:00PM same day. Like always etrailer's fast delivery time and product info with installation video on your website are very helpful. 1st photo OEM bump-stop, 2nd photo OEM bump-stop removed, 3rd & 4th photo Timbren SES kit installed.

Accolade XT 35L - Timbren SES (TFRSDE - 12k support) loaded in the sweet spot.

These Timbrens should be used on F600 and F550 models. Do NOT use the spacers that come in the box. Just install the Timbrens without the spacers and you are good to go. When FULLY loaded (full gas/water and gear), the Timbrens should compress about 1/2”, which seems to be the sweet spot. The end results are as follows:
1. Better bump absorption and much better rebound. The inside chatter is more of a low sounding rumble and the suspension rebound is really quick.
2. Much better sway control and overall stability.
3. The drive feels more balanced front to rear. The rear drop was reduced by 1”. I think that allows the leaf springs and shocks to work in a more neutral position.

These are worth every penny and are a cheap “set it and forget it”way to improve your ride quality!



by:

Added these to my F250 Super Duty. I carry a golf cart on a Diamond back bed cover. Can be a little top heavy. Perfect addition to my suspension- greatly reduced the sway.



by:

Easy to install using basic hand tools, and stopped the "sag" when I hook up my Casita travel trailer



by:

Helps prevent about 1/2" of sag with my 175lb-tongue weight trailer and easy to install.



by:

Great product. The ride and body roll at the rear axle are notceably improved (1989 Ford E350 Class C RV , 27 ft). I give it 4 stars because the installation was slightly complicated due to the rear brake lines needing to be slightly bent to provide clearance for the U bolts supplied in the kit. Great product and wish it came in a 5000 lb version.



by:

2,000 miles in on a trip from the east coast to the Canadian Rockies these work great while loaded and towing. Close to zero bounce while towing, I love them. Unloaded, however, the ride in my 2026 Tundra has gone south. There is a noticeable, abrupt stop of the units hitting the axle when going over any kind of bump. When I get home and back to regular driving, I may just take them off, its that bad.



by:

I've had these on our tow rig for a year now and I added buy them again today if I needed them.these have worked much better than airbags for our coil spring rear suspension to handle the tongue weight of our trailer. The SUV sits level when the trailer is on and it handles bumps and sway better than the airbags did providing much more comfort to us in the vehicle. Unloaded, we don't really notice they are there, unless, we have all the kids and some friends loaded up and you will fell them work when going over bumps.i do all my maintenance on the vehicle's and inspect these regularly and I cant see any wear so far even though we've gone on 6 trips with our trailer with about 5000 miles doing so.
I cant say these are the best for every truck or SUV, but for ours it is the best and I definitely would recommend to others.



by:

Order came fast and right. E-Trailer gets it the first time !!
Installed fit perfect



by:

Well they are exactly what I thought it would be. Hard for me to say it's what I needed yet.
I installed them on a homemade trailer from a salvaged 2001 base model tacoma. Once I get finished building it out and have some weight in it I'll have a better idea. But from what I've seen so far on a couple test drives they should come into effect when needed.
For reference I building an Tacoma based trailer with an ARE Contractor topper with a Naturnest roof top tent on the very top. So to counter and sway these should be very helpful. At least I hope so. I'm not an engineer but I did stay at an Holliday Inn once.

The Timbren SES is a simple solution for rear squat when towing. When hitched to my 30' Airstream Globetrotter (8800 GVWR) with a tongue weight around 1200 lbs, my Silverado 2500HD had a bit more squat than is ideal. I shopped airbags but didn't want to spend ~$2K for the set up and didn't want the hassle of installation and forever chasing air leaks. The Timbren SES literally installs on the Silverado in about 15 minutes. So simple. No bags, no compressor, no wiring, no air lines, no leaks. And WAY less expensive to boot. Just returned form a 600+ mile trip and it towed flawlessly.



by:

A very simple and straightforward installation once you get the oem bumper stops off (had a shop do that)
Timbren worked with me as I had a non OEM frame height (vehicle was lower than stock) to recommend the proper kit. Highly recommend contacting timbren if you are unsure of the proper kit to use. Ride is more stable. It does feel stiffer and less bouncy but am looking forward to seeing how it performs with my truck camper. Truck is a 1998 dodge ram 2500. Brake line over left side of axle needed to be secured to prevent damage.



by:

The Timbren overload spring/bumper was east to install and did what it was supposed to do when I hitched up a camp trailer. These did not negatively affect the ride by any means and I don't have to worry about the troubles with air bags.



by:

Stiffens and corrects kneel in rear end of 2023 Chevy Silverado 1500. You will notice a stiffening of the rear end suspension while unloaded, but it’s a fair trade off to prevent sagging and porpoising while towing. I found it easier to pull the rear wheels and work from the side than underneath the vehicle while installing.



by:

The timbres bump stop is exactly the right height to meet the axel when the trailer is connected with all its weight onto the hitch. I have an Andersen weight distribution hitch and it levels out perfectly. The day picture is with the coach (Winn 2100bh) with factory equipment. The night picture is after the timbres are in place. Looks good.



by:

It has been almost a year since I installed Timbren Suspension Enhancement Systems (DVF350 and DVR350R) on the front and rear of my 2003 Dodge RAM Van 3500. These bumpers replaced the OEM bump stops that were on my van. I like the Timbren bumpers much better than the OEM bump stops because they provide a progressively cushioned response for suspension compression when traveling over significant humps like speed bumps in a parking lot, or curb ramps into driveways. I did not like the abrupt stop the OEM bump stops provided when traveling over the same objects. I installed the Timbren rear bumpers first, and after a few months of use, I decided to add them to the front. In both cases, the front and rear Timbren bumpers were easy to install once the OEM bump stops were removed. Installation required reuse of the factory hardware. On my van, the Timbren bumpers are not always engaged. Under normal load and travel conditions the bumpers are relaxed and about 1/2” away from the suspension landing points. However, their presence is much appreciated and very noticeable when the van is carrying heavy loads or handling significant humps.



by:

2022 F250 Super Duty. Super easy to install. I have about 3/4" gap between the spring and the plate. Time will tell how they impact the ride quality and how much sag they mitigate with my 5th wheel hooked up.



by:

Great upgrade when pulling our 6500lb travel trailer. Helps with sag and control on the road on our Ram 1500. Change the stock shocks and if you choose, upgrade your stock springs, and you'll get the most out of your half ton.



by:

Absolutely Pleased with the TIMBRENS. They were easy to install, and took less than an hour to install both. I noticed a slight stiffness in the ride as the rear bounced over a bad roadway. Towing is great, with a nice level and smooth ride. I am glad that I did not order the heavier duty Timbrens, than what was recomended for my truck. I believe the ride would have been too stiff. If you look at the photos showing the timbrens, the truck is still lifted in the rear, so what you see is a big gap between the rubber, and the steal plate. When the truck is lowered, there's 1" of space as it should be. BTW, I have been purchasing from etrailer for years now, and I have to say that I have never had any issues with any orders. They are my go to folks for all of my vehicle suppension stuff and trailer stuff. You can't go wrong with buying from them.



by:

Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!

  • Rear Suspension Enhancement Recommendation for a 2008 Ford F-450 Super Duty Dually
    In terms of air springs that are rated higher than # F2446, we do not carry a set rated higher for a 2008 Ford F-450. However, if you do not need to level the bed side to side often, which is one benefit of air springs, I would go with a Timbren system instead. Take a look at the Timbren Rear Suspension Enhancement System, # TFRSDP. It is rated for up to 12,000 pounds which is more than twice the capacity of the air springs.
