Features to know about

Stay Level When You Tow: 2,000 lb Rear Suspension Support

Heavy trailers and loaded truck beds can cause your suspension to sag, throwing off your steering and braking. With a 2,000 lb capacity on the rear suspension, these bump stops keep your truck level, helping you maintain control and stability whether you're hauling tools for work or towing a travel trailer across the country.

Minimize the Bounce: Progressive Spring Rate Absorbs Impact

Rough roads and sudden dips can make for a jarring ride, especially when towing or carrying heavy loads. These bump stops use a progressive spring rate, meaning they engage softly under light loads and firm up when carrying heavier weight. The result? Less bounce, more stability, and a smoother ride, whether you're rolling down the highway or tackling a gravel road to the campsite.

Protect Your Frame and Suspension: Cushions Road Shock

When your suspension bottoms out, it can stress your trucks frame and wear out components faster. These bump stops absorb the impact before it can cause damage to your trucks frame, shocks, or axle, helping to extend the life of your suspension components. The included powder-coated brackets resist rust and corrosion, ensuring long-term durability even in harsh weather and off-road conditions. Whether you're carrying a bed full of gear or pulling a fully loaded trailer, your truck stays protected so you can keep driving with confidence.

Stronger Than OEM: Durable Rubber Compound Handles Heavy Loads

Timbren's bump stops are made from a high-quality natural rubber compound designed to withstand extreme conditions. Unlike standard bump stops, these won't degrade quickly under stress. They maintain their shape and performance, even under heavy loads or repeated compression, ensuring long-term reliability for your trucks suspension system.

Stable and Level Under Heavy Loads: Reduces Sag and Trailer Sway

A loaded truck bed or a heavy trailer shouldn't mean a sagging rear end or unstable handling. These bump stops reduce squat and sway, keeping your truck level for better braking response, more stable steering, and improved traction. Whether you're towing a camper, boat, or hauling gear in the bed, you get a safer, more controlled ride.

Bolt-On Design, No Air Lines Needed: Simple, Hassle-Free Setup

Forget about running air lines or checking pressure before every haul. These bump stops install with a straightforward bolt-on design, so once they're in place, they're always ready to work. Just install them and get back to towing, hauling, and hitting the road without any extra maintenance.

  • Recommended Timbren Rear Suspension Enhancement For A 2019 Toyota Tacoma With 4WD
    Suspension enhancement systems like Timbren springs are perfect for the scenaro you're describing. These solutions supplement your factory suspension but don't necessarily increase your capacity. Timbrens are hollow rubber springs that sit above the rear axle to help stabilize and level your Toyota Tacoma. Below are what I recommend of the available spring choices. For off road applications, I recommend the Timbren Active Off-Road Bumpstops # TABSOSR for vehicles if the axles are...

  • Can Timbren Kit Fit with Roadmaster Active Suspension Kit on 2022 Chevy Colorado
    Hey Christopher, I would not recommend that as the Timbrens are notoriously harsh. The two would technically fit together but if you have your RAS kit all the way maxed out and still need more support you probably are over the capacity of your truck. Is that possible?

  • Blue SumoSprings For A 2023 Nissan Frontier 4x4 With The King Cab
    Hi Drake, welcome back! The SumoSprings # SS96EV is indeed only for the crew cab models of 2023 Nissan Frontier, so what you are going to want is the blue SumoSprings Solo Custom Helper Springs # SSR-612-40. This one is specific to the king cab models and just to make sure, I verified that directly with SuperSprings. As for Timbren options that will fit your king cab, we have the following two options: Timbren Rear Suspension Enhancement System - 3,000 lbs # TTORTUN4L Timbren Active...

  • What are the Dimensions of the Timbren Active Off-Road Bumpstops for Toyota Tacoma?
    The Timbren Active Off-Road Bumpstops - Rear Suspension - 3,600 lbs # TABSTRFK have bump stops and mounts that are 5-1/2 inches tall overall and u-bolts that are 8-1/4 inches long and 3-3/4 inches on center. I've attached a photo to assist. These jounce springs will mitigate sag when towing and they will work great for your off-road towing.

  • What Is The Difference Between Timbren TABSOSR And TTORTUN4?
    Hello Jhon, thanks for reaching out. Both the Timbren kits you mentioned are going to fit the 2013 Toyota Tacoma. The difference is the application and the weight capacity. The # TABSOSR are intended for off-road applications and are rated for 3,600 lbs. The # TTORTUN4 are intended for typical on-road towing hauling application and they are rated for 6,000 lbs. What are you hauling with you Tacoma? A Camper or trailer? Reply on this page.

  • Replacement Bump Stops for a 2016 Chevrolet Colorado LT with Rough Country 6 Inch Lift Kit
    For starters, if you are going to be using your 2016 Chevrolet Colorado LT for towing then the Timbren Suspension Enhancement System would be correct but if you going to be using your 2016 Chevrolet Colorado LT for off roading then I recommend using the Timbren Active Off-Road Bumpstops. The Off-Road system has a softer spring which you will want for hard impacts whereas the SES system has a harder spring that will be better for constant loads. I called Rough Country and the said that...

  • Suspension Enhancement for 2019 GMC Canyon 4x4 Towing Boat Trailer and Off-Roading
    Hi Dave; Timbrens work well for some applications but I don't think the # TABSOSR is going to be the best option for your application. These would be better if you're strictly off-roading frequently. Instead, I recommend the SumoSprings Solo Custom Helper Springs # SS75FR. The SumoSprings will give you the added support you're looking for and help with body roll and sway while towing your boat trailer. They also aren't harsh like the Timbrens tend to be so you won't have a terrible everyday...

  • Are Timbren Active Off-Road Bumpstops Compatible With Spacers
    Hi Dustin; according to Timbren the # TABSOSR cannot be used with spacers. To get the support you want without switching kits I would try reaching out to Timbren again since they do have a satisfaction guarantee. When they have been here in the past they told us if a customer reaches out to them and says they are too stiff or not stiff enough they are willing to make new ones and adjust it so they're happy with the product. I don't think we have seen anyone try this yet but that came...

  • What Timbren Kit Should I Get for my 2017 Toyota Tundra SR5
    Thanks for your question, Jesse! I've got some really good news. Based off some information from Timbren, you wont need any sort of spacers for the front bump stops even with the factory leveling kit. One less think to worry about! The best kit for your set up is going to be part # TABSTOF and it has a 1,000 lbs rating. They offer another option but that kit has a 14k rating so would be more suited for a snow plow type of application. Now for the rear kit I recommend going with kit part...

  • 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...

  • Height Of Timbren Springs and Vertical Wheel Travel Loss In 2019 Toyota Tacoma
    When installing any Timbren system on the 2019 Toyota Tacoma you should have about 1/2" to 1-1/2" between the frame and the spring after installation. 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. When you switch out the factory bump stops for the Timbren springs...

  • 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...

  • Rear Helper Springs/Suspension Enhancement for a 2018 Chevy Colorado ZR2 Diesel
    For your 2018 Chevy Colorado ZR2 Diesel I recommend RoadActive Suspension # RAS4617. This system will provide extra support when towing and/or carrying loads in the truck bed as well as help with overall stability all without affecting the unloaded ride quality of the truck. The kit comes assembled and ready to install so you will have more time for your adventures!

  • 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...

  • 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.

  • SumoSprings or Timbren Springs For a 2016 Toyota Tundra For Hauling Occasional Loads
    I recommend using the SumoSprings Solo Custom Helper Springs # SSR-610-47 on our 2016 Toyota Tundra. As you will only be hauling the additional weight a few times a year for a short distance this will provide you with the best ride quality when you are using your truck as a daily driver. The Timbren Springs # TABSOSR will create a stiffer ride both while hauling additional loads and while daily driving. I only recommend these types of springs for vehicles who will see additional weight...

  • Timbrens or Firestone Air Bags for 2019 Toyota Tundra TRD Towing a Trailer
    I highly recommend the Firestone Ride-Rite Air Helper Springs # F2445 for your 2019 Toyota Tundra TRD over the Timbren Active Off-Road Bumpstops # TABSOSR because the Firestone air bags are going to be a greater help to your Tundra when you're towing. In regards to the suspension travel you asked about, the Firestone air bags only need to be inflated to a minimum 5 psi so when you aren't towing it will essentially be like you don't have them on. The Timbrens are going to be much more...

  • Will Timbren Helper Springs Cushion Ride of 2018 Chevy Colorado when Towing with Weight Distribution
    It is possible that the weight distribution system you are using is rated too high for the total tongue weight of the trailer. Total tongue weight is the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle in your 2018 Chevy Colorado. So for example if the trailer tongue weight is 500 pounds and you have 40 pounds of stuff behind the rear axle the total tongue weight would be 540 pounds. The 750 pound Blue Ox systems are rated...

  • Comparing Timbren Suspension Enhancement for 2018 Toyota Tacoma
    There are six different Timbren kits for suspension enhancement that all fit your 2018 Toyota Tacoma. Four are for the rear and two are for the front. Of the front two, part # TTOFTUN4 is designed for adding support when you put a snow plow on the truck and # TABSTOF is an active bump stop that cushions the shock when off-roading. A couple of the rear kits are designed to support the rear of the truck when either towing a trailer or adding weight in the bed. Use part # TTORTUN4 if your...

  • Recommended Bump Stop Suspension Enhancement for a 2017 Chevrolet Colorado
    Really the only difference between the Timbren part # TABSGMFCC and part # TABSOSR for your 2017 Chevrolet Colorado is that the former is rated for up to 1,000 lbs while the latter is rated for up to 3,600 lbs. 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. If you are looking for ride comfort though I recommend going with the SuperSprings Solo Custom Helper Springs # SSR-212-40....

  • Comparing Timbren Kits for 2022 Toyota Tacoma
    There is an interesting amount of Timbren kits that fit your 2022 Toyota Tacoma long bed. The part # TABSTRFK is a standard duty kit that comes with a U-bolt flip kit helps with ground clearance. # T72FR is a severe service kit for 3 leaf springs which means it's going to be really harsh, # T62FR is same thing but for 4 leaf spring packs. # TABSOSR is a standard duty kit which means it'll give best blend of support and ride quality. This would be what I would recommend.

  • Recommended Timbren Suspension Enhancement for a 2022 Nissan Frontier
    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.
