SuperSprings Intl Vehicle Suspension - CSS-1125

  • Towing/Load Leveling
  • Bump Stops
  • SuperSprings Intl
  • Standard Duty
  • Front Axle Suspension Enhancement
  • Rear Axle Suspension Enhancement

Get the cushioning power of SumoSprings for your coil springs and keep your ride comfortable. The wedge-shaped springs fit between the individual coils of your existing springs and help support extra loads on your front or rear suspension.


Features:

  • Installs easily on front or rear suspension coils

  • Made in the USA


Specs:

  • Application: front or rear coil spring suspensions
  • Designed to work with a suspension system that is in good working order
  • Coil SumoSprings will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's weight limit for your vehicle.
  • Limited Lifetime warranty
  • 30-Day satisfaction guarantee


Insert these helper springs in between the individual coil loops in either your front or rear coil springs to defeat driver fatigue and add better support for heavy loads. Most factory front coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. The rear coils may struggle with supporting the extra load placed on your rear axle when you're towing a trailer or using a hitch-mounted cargo carrier or bike rack. If your coil springs are totally squished under a load, the lack of shock absorption can be harsh on your backside, especially if you spend long hours sitting in your vehicle while clearing snow or driving to a campsite.


Coil SumoSpring installed between rungs of coil spring

Inside each helper spring, a core of microcellular polyurethane foam adds cushioning between your coils to make your ride more comfortable. Each doughnut-shaped spring has H-shaped channels at the top and bottom that fit to the rung of an individual coil in your front or rear coil springs. The cushioning absorbs shock, but also works progressively to better support weight, keeping your truck level.


Unlike air springs that fit inside your coil springs, these polyurethane springs require no air pressure monitoring, and they are easier to install. Say goodbye to air lines, valves and air tanks and hello to maintenance-free suspension support. Unbumpify your ride with Coil SumoSprings for coil suspensions.

  • What is the Difference between the SuperSprings Coil Insert # CSS-1125 and # CSS-1125R
    The SuperSprings Coil Spring Inserts, # CSS-1125 and # CSS-1125R, are the same exact part and both will fit your 2011 Honda CR-V EX-L. The actual part number from SuperSprings is CSS-1125, but we put an R or an F on the end of the part numbers for these products to indicate if it is used for Rear coils springs or Front coil springs on a particular vehicle. For example, on your CR-V, these springs are used on the rear coil springs, so we put an R at the end of the part number. These springs...

  • Availability Of Rear Suspension Enhancement for 2017 Kia Sorento
    I may have an option for you, but there is not a suspension enhancement option confirmed to fit your 2017 Kia Sorento. If you can measure the distance between the middle coils of your rear coil springs, there may be a Coil SumoSprings option. The Coil SumoSprings like the # CSS-1125 install in your coil springs and will help to support your suspension when you are towing or carrying a heavy load. You will want to take the measurement with the vehicle on the ground, and make sure that...

  • Recommended Ball Mount for a 2010 Toyota RAV4 With Factory Towing Package
    For your 2010 Toyota RAV4 Factory Hitch, you'll want about a 3 inch rise. You can confirm this by measuring from the ground to the top of the trailer hitch, and measuring from the ground to the bottom of the coupler. Then, subtract the higher number from the lower number. It does sound like you've gotten this about right though. If yours is a 1-1/4 inch hitch, I recommend the Draw-Tite Drawbar, part # 36063. This will give you a correct, 3 inch rise with a 3/4 inch ball hole diameter....

  • Determining Which Coil SumoSprings For Rear Of 2016 Toyota Highlander FWD
    I have a different option for you, but while you are correct that the # CSS-1168F is a confirmed fit for your 2016 Toyota Highlander Front Wheel Drive it is designed for the front suspension and would not help while towing a travel trailer. While there is not a confirmed suspension enhancement option for the rear of your Highlander, if you can measure the distance between the coil springs on the rear of your vehicle I would be happy to see if there is a option that will fit. You will want...

    I may have an option for you, but unfortunately there are not suspension enhancement options confirmed to fit your 2021 Toyota Highlander V6. With that said one of the Coil SumoSprings Helper Springs such as the # CSS-1168R you were looking at may still work but you will need to measure your coil springs to be sure. With the vehicle on level ground measure the distance between the middle coils in your rear coil springs. If you can provide this measurement I would be happy to see if there...

  • Will the SuperSprings Coil SumoSprings Fit a 2015 Volkswagen Passat TDI
    The SuperSprings Coil SumoSprings, # CSS-1125, will fit your 2015 VW Passat TDI. You are correct that the Firestone airbag kit, # F4176, will not fit the TDI models, but based on the coil spring dimensions you provided in the attached diagram, these SumoSprings will work for you and help level the rear end of your Passat with the weight of the bike rack and bikes.

  • Suspension Enhancement Product for 2020 Toyota Highlander
    Although the # AL60732 Air Lift air helper spring system you'd looked at isn't a fit for your vehicle, we do offer an option that would work for you. SuperSprings offers a Coil SumoSpring product for the 2020 Toyota Highlander gas engine equipped models. If your Highlander is a FWD model, use # CSS-1125 or for an AWD model, use # CSS-1145. The Coil SumoSprings are actually pretty ingenious. They install in between the coil loops in your rear coil springs to provide extra support for...

  • Comparing Suspension Enhancement and Weight Distribution Hitch For 2020 Ford Explorer Towing TT
    Since your 2019 Trailmanor 2720QS weighs over 50% of your 2020 Ford Explorer a weight distribution hitch is recommend, but you will need to double check a few things on your trailer to make sure you have enough room on the trailers frame. Since your trailer has a GVWR of just over 4000lbs and tongue weight is typically 10-15% you should expect to see between 400-600lbs tongue weight if your trailer is loaded to the GVWR. You will also need to add in the weight of any cargo stored behind...

  • Rear Coil SumoSprings on a 2012 Ford Expedition
    Our part # CSS-1125R is confirmed to fit on your 2012 Ford Expedition. This is actually the same exact part as the # CSS-1125. The "R" on the end of the part number indicates that it is a fit for the rear of your vehicle. In short, the Coil SumoSprings # CSS-1125 will fit your Expedition for the rear axle.

  • What Options Are There For Rear Suspension Enhancement On 2016 Audi Q5 When Towing A Trailer?
    I may have an option for you, but at this time there is not a rear suspension enhancement option confirmed to fit your 2016 Audi Q5. If you can measure the distance between the middle coils on your rear coil springs, there may be a Coil SumoSprings option that will fit. The Coil SumoSprings like the # CSS-1125 install in the middle of your coil springs and support your factory suspension by up to 30%, and would help to prevent rear suspension sag when towing a trailer. You will want to...

    If you're looking for a steering stabilizer or anti-sway bar we unfortunately do not have a confirmed fit from our supplier, Roadmaster, at this time. That being said we do still have suspension upgrades available to help with your ride quality. If you're looking to replace your coil springs with a heavier duty option then we have the SuperCoils Custom Suspension Coils # SSC-51.

  • Are There Rear Suspension Enhancement Options for a 2016 Honda Pilot
    I might have an option for you but we don't have any confirmed rear suspension enhancement options for a 2016 Honda Pilot. That said, the Coil SumoSprings Custom Helper Springs may work but we'd need a measurement of your rear coil springs to confirm. You'd need to measure the gap between the coils in the middle of the spring with the vehicle as it sits. You do not need to raise it. Ensure that each side of the vehicle is within 1/4" (0.25") measurement of the other. If it's 1" for example...

  • Suspension Helper Recommendation for a 2019 Subaru Crosstrek
    The only suspension enhancement option we offer for a 2019 Subaru Crosstrek is the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension part # CSS-1125. The SumoSprings install between the coils on the coil springs and prevent them from compressing when loaded. They are easy to install and can be removed when not in use. They will do a great job of providing support while towing or hauling heavy loads.

    According to SuperSprings, the # CSS-1145R won't work with a 2021 or 2022 Honda Odyssey, but the good news is that they DO have an application that WILL work. You'll want to use part # CSS-1125 which is a fit for that year range Honda Odyssey. If you click the provided link, you can see a video showing a typical installation.

  • Rear Suspension Enhancement For A 1998 Ford Crown Victoria
    The Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Front or Rear Axle Item # CSS-1125 are not compatible with the 1998 Ford Crown Victoria. To add suspension enhancement to the vehicle I recommend the Air Lift 1000 Air Helper Springs for Coil Springs - Rear Item # AL60798. This kit allows you to adjust the air pressure in each bag to support different weight added to the vehicle up 1000lbs for better ride quality.

    I just checked with Supersprings International and your 2021 Toyota Highlander AWD needs the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Front or Rear Axle item # CSS-1125. These will not fit the Hybrid models. These are for front or rear coil springs and are designed to work with a suspension system that is in good working order.

  • Correct Number of Coil SumoSprings Custom Helper Springs Needed for 2020 Toyota Highlander
    The Coil SumoSprings Custom Helper Springs part # CSS-1145 for AWD or part # CSS-1125 for FWD will use one spacer per coil spring, you cannot use two per side nor would you want to as the ride would be too stiff but there is not enough room anyhow. These will be great for towing or hauling heavy load and they are currently the only option we have to help with rear end sag/squat.

  • Suspension Enhancement Recommendation for a 2006 Honda Pilot
    For your 2006 Honda Pilot I have a suspension enhancement solution that I can recommend, but the part # CSS-1125 would not be it since it is not confirmed as a fit. Instead you would want the Timbren system part # THROD2. This does not fit in the coils at all so you would not need to compare it's dimensions to what you already have.

  • Suspension Enhancement Recommendation for 2013 Toyota Prius
    We actually only have one suspension enhancement fit we can recommend and it's only for the 2013 Toyota Prius and not the V. For that you'd want the Firestone air bag kit part # F4136. The SumoSprings you mentioned cannot be used on the Prius.

    I may have a different option for you, but at this time there are no air helper spring kits or suspension enhancement options that are confirmed to fit your 2018 Toyota Highlander. One option that may work is Coil SumoSprings like the # CSS-1125 as these are pretty universal and the correct one is dependent on the space between your coil springs.

  • Coil SumoSprings Helping Sag On 2019 Subaru Outback Wagon
    The SumoSprings # CSS-1125 will help your front and back suspension from sagging as much on your 2019 Subaru Outback Wagon. Putting these on the rear axle will help your suspension from compressing as much which in turn will help your front end from raising up so bad. I understand this because when I tow a trailer that's heavy and/or uneven I hate having people flash their lights at me when I'm going down the road! I know I can't help it but they don't know that. This makes me uncomfortable...

  • Suspension Enhancement to Prevent Sagging While Towing With 2021 Toyota Highlander XLE
    Yes, the Coil SumoSprings Custom Helper Springs # CSS-1145 will help prevent the sag you are experiencing. These will provide additional support and use progressive load control so they get stiffer as you add more weight. The # CSS-1145 will work for the AWD model. If you have the FWD model then you can use the # CSS-1125 instead. Proper installation of the SumoSprings will not damage your vehicle or void the warranty.
