  • 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...

  • 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...

  • 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.

  • 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.

  • 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.

  • 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...

  • 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.

  • 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...

  • 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...

  • 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 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!

  • 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...

  • Timbren Suspension Enhancement System for 2018 Toyota Tundra 4WD
    The Timbren Rear Suspension Enhancement System # TTORTUN4 is a great SES that fits your 2018 Toyota Tundra. The Timbren line of SES is really popular and there are several models available. The # TTORTUN4 features heavy duty rubber springs with a 6,000 lb weight capacity. The Timbren Active Off-Road Bumpstops # TABSOSR features a lighter duty rubber spring with a 3,600 lb weight capacity. Both products fit your vehicle and install in the same way, but the # TTORTUN4 is better if you expect...

  • 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...

  • 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...

  • Suspension Enhancement Recommendation for 2008 Toyota Tundra
    We have suspension enhancement that fits your 2008 Toyota Tundra that will help you tow within the capacities of your truck, but nothing we offer will give you higher capacities than what you already have. Our suspension enhancement kits like the Timbren part # TABSOSR which fit your Tundra will help reduce sag when towing a heavy trailer but you have to make sure the weight of the trailer is less than the towing capacity for the truck.

  • Comparing Rear Suspension Enhancement Systems For A 2018 Nissan Frontier
    Thanks for the helpful information! For your 2018 Nissan Frontier there are two really nice rear suspension-enhancement systems that I recommend looking into. They are the Firestone Ride Rite Air Bags - Rear Axle # F2558 and the Timbren Active Off-Road Bumpstops - Rear Suspension # TABSOSR. Both setups will reduce rear-end sag and reduce body roll on sharp turns. The Timbren setup is a jounce-style spring that will replace your factory bump stops and will help your factory suspension with...

  • Rear Suspension Enhancement for 2021 Chevy Colorado 4x4
    For your 2021 Chevy Colorado 4x4 we have the Timbren rear suspension kit part # TABSOSR as a confirmed fit that would do an excellent job reducing the sag you are experiencing. SumoSprings does not have a kit for your truck at this time but the Timbrens are essentially the same design as it's a jounce type bumper designed to replace the bump stop.

  • 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 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...

  • 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.
