Timbren Vehicle Suspension - TABSOSR

  • Bump Stops
  • Rear Axle Suspension Enhancement
  • Timbren
  • Light Duty


Timbren's Active Off-Road Bumpstops provide off-road enthusiasts with greater control over their vehicle's suspension travel. Using progressive-rate springs means that instead of a hard stop at the end of axle travel, the axle energy will be absorbed when bottoming out, producing smooth, predictable, and quiet axle engagement and disengagement. The progressive rubber springs absorb the harsh jolt at the end of axle travel, giving you a gentle ride the whole time.


Unlike your factory bumpstops, Timbren's bumpstops are constructed of a superior natural rubber compound, ensuring the bumpstops will continue to operate even after a lifetime of off-road abuse. And the steel brackets and disks are lazer cut before they are painted with a durable, long-lasting powder coat finish to ensure protection and long life.


Features:

  • Designed to maximize axle travel
  • Smooth axle engagement and disengagement
  • Enhances rear suspension performance
  • Progressive spring rate
  • Absorbs energy and cushions road shocks
  • Constructed of a natural rubber compound
  • Stronger than OEM bumpstops
  • Easy installation - hardware included
  • Capacity: 3,600 lbs
  • Lifetime warranty
  • Satisfaction guarantee

What a great product and less upkeep than bags. I've been towing a 25 camper and loads of gravel while sitting safe and level! Selling the truck for something bigger that will also get the Timbren treatment



by:

I purchased this a week ago... not a year ago! I'll be hitching the trailer this weekend to check out the new suspension addition. jm

2012 Toyota Tundra

I had these on my Tacoma and liked the way they worked so much that I got a set for my new to me Tundra. You don't notice anything until you put a load on the truck. Then you feel more stable under load and don't have to worry as much about the leaf springs. The install was done in 15 minutes

I pull a 20 ft car hauler with the Tundra and recently hauled a car to Arizona then hauled another back. The frame just touches the top of the Timbren when loaded. After 3,000 miles of driving I am even more convinced that this is a great product. The truck never squats from trailer load and the Timbren also keeps the ride smooth straight and steady when pulling a load. When unloaded there is about a one inch gap between the frame and the Timbren so it drives like stock when lightly loaded or unloaded.



by:

Installation was a breeze! Followed the instructions and lifted the truck up using a jack under my hitch, loosened the u-bolts, removed the factory bump stops and installed the timbrens! Took 5 minutes for each side, and 5 minutes to setup and take down setup. 15 minutes max. Very easy to do. I believe I am going to need a 1” spacer as I have 1.5” Icon add-a-leaf packs in order to get them to engage while towing.



by:
2009 Toyota Tacoma

These do what they're built to do. I overland a lot so when the truck gets weighed down with gear she tends to squat a little and when I go through bumpy areas the factory stops would slam the frame. No any more with these Active Bump Stops. A much smoother ride and less body roll when cornering.



by:

The factory bump stops were harsh. These engage sooner and while firm they do not crash like the OEM.
Easy install.



by:

Very easy to install, haven't traveled with trailer yet but will be traveling in April.



by:
2010 Toyota Tundra

Ordered for my 2010 Toyota Tundra. Parts came quickly and had them installed in about 20 minutes. Just needed a good vehicle jack and impact wrench and was very easy. These have greatly reduced the sag when pulling my camper and very satisfied.



by:

Well after used the Chat online with Carol I ordered. Paid for 2 day shipping. Got it in 2 days.

Total install time 1 hour.

Been using the front and rear Timbrens on MY 2020 Nissan Frontier King Cab SV 4x4

Work great, save my air bags from getting pinched if I let them get deflated.



by:
2014 Toyota Tacoma

I have a medium-duty truck and recently purchased a camp trailer. Well, when I pulled the trailer home for the first time the back of the truck was weighed down. I installed the new Timbren Active Off-Road Bumpstops and they improved the load capacity immensely. When I get the cash saved up I plan on purchasing the Timbren Active Off-Road Bumpstops for the front. Worth every penny.

I have had Timbrens on several trucks! I always thought they worked great! I plan on putting these on a new Tacoma, which I will not yet until the end of September so I hope they fit! They are a very good product otherwise I would not use them!

Very effective upgrade and install wasn’t to bad either. Highly recommended! 2003 Toyota Tundra.

These were a breeze to install with rear of my Frontier Pro4X on ramps. they fit perfectly, and are a drastic improvement over the rock hard rubber factory bump stops.

The Timbren OffRoad bumpstops have been working great, ride quality is much improved when suspension bottoms out and these are great bumpstops. Intstallation was a breeze.



by:
2018 Toyota Tacoma

It only took less then 30 minutes to install, What a big improvement!! Installed on a 2022 Toyota Tacoma Off Road, towing a 2018 Coachman Ultra Lite, 5900 lbs.



by:
Ford Escape

They seem to perform just fine, absorbing bumps and impacts etc. However they collect water like little buckets and the bolts are clearly corroding on the inside of the bumpstops since they have no drainage. Adding a way for water to escape faster than evaporation would be a good improvement to the product!



by:

The Timbren bumpstops improved not only the loaded ride of the frontier, they also, imho, helped with the unloaded ride. This was on a 2018 frontier, the factory leaf spring pack is not made for hauling much, or a trailer with any tongue weight over 200#'s.
I had an issue with missing\wrong parts, I called e-trailer, they where wonderful to work with on fixing this issue.



by:

Correct hardware for install was not included, I bolted them right to the frame and the axle come up to them. They are great I haul heavy loads long distances and they exceed my expectations. Way better than the air bags that my tire wore holes in while off roading. These rubber bump stops are bullet proof and worry free



by:

I've got a 2019 Tacoma TRD Offroad Double Cab with otherwise stock suspension: Bilsteins and 4 leaf spring in rears. GVWR is 5600lbs and I run it at about 5200lbs with all my racks and add-ons. I've only off roaded a couple times (with even more load) and didn't have any issues bottoming out my stoppers, but I often jarringly hit my stoppers in the streets of San Francisco, most notably heading east on Fulton St at 43rd Ave at a bus stop transition (35 mph speed limit). I was hoping this quick fix would alleviate the problem without stiffening my normal ride. I find the truck, when unladen, is bouncy at highway speeds on concrete roadways (gets a sea sick inducing bounce when the suspension becomes harmonic with the cracks and surface waves), so I didn't want to tighten up the suspension at all.

I got the Timbren Active Offroad bump stops yesterday and it took me just over 30 mins to install with no hassle. There is only a hair gap between the top of the bump pad and the frame when parked. I took it for a test drive through the neighborhood and it felt like it did stiffen the ride a little bit, but had more control over bumps and dips, and less side sway. Then this morning I took it to the fateful Fulton test spot. Boy did it hit hard today. The change in my trays didn't go flying as usual, but I did bottom out the new bump stops with a thud. So their performance was not as great as I had hoped, but it did make it a little better. My expectation may not be reasonable, but I thought its road performance with be better than off road (I guess you go slower off road though). I'll have to see over time and perhaps consider more suspension upgrades. One thing I am curious about is how much bed sag I will have if I'm hauling stone. I've ridden on the stock bump stops with trips from the yard, so although these are not designed for towing or hauling, I'm hoping they will help the sag some. Maybe I can update this in a few weeks.



by:

I threw these on a Toyota Tacoma TRD in hopes of eliminating bottoming out on the suspension and increasing pay load a bit. I use the truck mainly for work around my farm and as my off road machine. I am more than impressed on what the Timbren bump stops delivered. The ride is softer in rough terrain and the truck barely squats when loaded full of feed or piled high with fuel, gear and animals during hunting season.



by:

Very easy to install.



by:

Easy Install, about an hour each side.
Changes
nothing to standard suspension until there is a load on them. When loaded you don’t have the banging with regular stops and steering and cornering are the same as unloaded. The biggest load I’ve carried is 3,400 lbs.
Make sure you check load rating on your tires before you add that much weight.

timbren were a perfect fit for my tacoma and was able to install the parts on myself they will make a big difference for leveling out the vehicle when pulling my travel trailer

  • How Much Space Should There Be with Timbren Active Off-Road Bumpstops On 2007 Toyota Tacoma
    The Timbren Active Off-Road Bumpstops part # TABSOSR which are a fit for a 2007 Toyota Tacoma are designed so that there is more space between the spring and frame to allow the suspension to articulate freely when off-road. If you're looking for a spring which is closer and provides support sooner you would instead want to go with the Timbren Rear Suspension Enhancement System part # TTORTUN4 which is designed to sit around 1/2" to 1-1/2" from the frame. If the truck has been lifted you...

  • Will Timbren Kit for 2013 Toyota Tacoma Fill with Water
    Due to the design of the Timbren kit part # TABSOSR it would potentially fill with water if they were submerged. This eventually could lead to rusting out the base and even one guy remarked that when filled with water there is a "fart sound" when hitting bumps. The second part could be a pro or a con depending on how refined your sense of humor is. So instead of going that route I would recommend the SumoSprings Solo part # SSR-610-40 which does not have that void and is known for providing...

  • Timbren Suspension Enhancement that Fits 2013 Toyota Tundra
    For your 2013 Toyota Tundra that is towing a 6,500 lb travel trailer I'd go with the Timbren kit part # TABSOSR to help support the rear of it and reduce sag as this will give you up to an additional 3,600 lbs of support if needed. Other kits provide even more support but they would provide a harsher ride quality. With that said, I think your best option would be the RoadActive Suspension kit part # RAS34FR which provides adjustable support, is easy to install, and also provides the best...

  • Timbren Rear Suspension Enhancement For a 2005 Toyota Tacoma Pre-Runner
    We do have the Timbren Rear Suspension Enhancement System # TTORTUN4 for your 2005 Toyota Tacoma Pre-Runner 2wd. This kit has a rated capacity of 6,000lbs to reduce sag and improve stability. We also have the Timbren Active Off-Road Bumpstops # TABSOSR rated for a capacity of 3,600lbs. These will provide you with more suspension travel than the kit above. So while you will see more sag out of this kit when you load your Tacoma, you will have a smoother ride when unloaded.

  • Will SumoSprings Solo Custom Helper Springs Fit Nissan Frontier with 6 Lift
    The SumoSprings Solo Custom Helper Springs # SS98DR, which fit a 2014 - 2021 Nissan Frontier, will fit as long as the lift is a body lift and it doesn't actually lift the frame of your vehicle. If it does lift the frame then I recommend picking up the Timbren Active Off-Road Bumpstops # TABSOSR which will be a bit more rigid but you'll be able to add spacers like the 1" Spacer # A25723-90AH00 to help take up that extra space. You'll just have to measure the available space and choose...

  • Rear Suspension Enhancement Recommendation for 2018 Toyota Tundra
    For your 2018 Toyota Tundra the suspension enhancement I recommend is the Timbren kit part # TABSOSR because this kit installs easily, gives you the suspension support you need to greatly reduce the sag, and because it doesn't require monitoring air pressure or running air lines like the air bag kits do so it's very low maintenance. I attached a link to an install video for this kit for you to check out as well.

  • Total Height of Timbren Active Off-Road Bumpstops for a 2011 Nissan Frontier
    The total height of the Timbren Active Off-Road Bumpstops part # TABSOSR which are a fit for a 2011 Nissan Frontier is 4-5/8". If you want to add spacers you'll use the Timbren Spacer part # TA25722-90P00 and or part # A25723-90AH00. In regards to fitment, you can add spacers so there is no space between the contact point and bumper but this would not lift the truck and it could also result in a stiff ride.

Out of these options I would go with the set that has a higher rating. Since you do off-road driving you will want to use the off-road bumpstops referenced above.

    Unfortunately Timbren does not make their Timbren Active Off-Road Bumpstops # TABSOSR kit without the axle bracket, so if you don't need it you'll just ignore it and install everything else. To figure out if you need a spacer kit #T68MR you're going to need to measure between the frame of your trunk when empty to the rear leaf spring. If you measure anything between 6" to 7 1/2", then you're going to need a spacer.

You won't necessarily be losing wheel travel when you use a Timbren Rear Suspension Enhancement System on the Tacoma. I recommend either the # TTORTUN4 system if you have 4 leaf springs in the rear suspension or # TTORTUN4L if you have 3 leaf springs in the rear suspension.
