Insert these helper springs in between the individual coil loops in your rear coil springs to defeat driver fatigue and add better support for heavy loads. Most factory coil suspensions have a difficult time hauling added weight. 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 driving to your 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 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.

  • 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 Correct Suspension Enhancement For 2013 Nissan Juke SV
    I may have another option but unfortunately there are no Timbren or Firestone suspension enhancement options confirmed to fit your 2013 Nissan Juke SV. The only option is to measure the spacing between the coils of your coil springs as depending on the amount of space you have there may be a Coil SumoSprings option. You will measure this distance with the vehicle on the ground, and you will want to make sure each side is within 1/4" of each other. I included a diagram of how to take this...

  • Suspension Enhancement Recommendation for 2021 Kia Telluride With Suspension Sag When Towing
    Hey Stephen, I would go with the SumoSprings kit part # CSS-1125R if you prefer a zero maintenance solution that once you install it you can basically never have to think about it again. The Air Lift air bag kit part # AL29PD would also work but it would be a better solution if you're the type of person who enjoys fine tuning things since you'd have to make sure the air pressure is correct when towing and not towing.

  • What Coil SumoSprings Custom Helper Springs Will Fit a 2003 Honda CR-V?
    For your 2003 Honda CR-V you will want the Coil SumoSprings Custom Helper Springs # CSS-1125R. These are confirmed to fit your vehicle while the Springs # CSS-1094 you found are for a smaller gap spring and will not provide you with the stability and reduction of rear end sag you are looking for.

  • Determining If Any Rear Suspensions Enhancement Will Fit 2018 Tesla Model 3
    At this time there is not a suspension enhancement option confirmed to fit your vehicle but there might still be an option. What you will need to do is measure the distance between the coils in the center of your rear coil springs. Depending on the distance between the coils there may be a Coil SumoSprings option such as the # CSS-1125R which will fit. This option installs in between your center coils and stiffens up the springs to keep your vehicle from sagging when towing a trailer....

  • SuperSprings SumoSpring Compatibility with 2012 Toyota RAV4
    The Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle # CSS-1125R will fit coils with a measurement of 1.25 inches between coils according to my contact at SuperSprings. It most likely won't be different for the AWD model but they have only tested for the rear wheel drive at this time. If you measure your coils, you will be able to confirm if it is a fit or not. The only confirmed fit suspension enhancement we have for both the 2WD and 4WD RAV4 for the 2012...

  • Rear Suspension Enhancement Options For a 2022 Subaru Outback Wagon

These are designed to attach to the coil spring and will work to reduce body roll and level the vehicle.

  • Recommended Suspension Enhancement for a 2017 Subaru Crosstrek
    Yes, I do believe that the Coil SumoSprings Custom Helper Springs item # CSS-1125R are the best option you have to enhance your Crosstrek's suspension. These springs adjust progressively to the weight put on the rear of your vehicle. If you are loaded down they will keep your rear suspension from completely flexing causing sagging. The best part about these helper springs is you do not notice them when you're not towing a trailer. Unless you're loading your roof down with extra gear you...

  • SumoSprings Recommendation for a 2006 Ford Explorer Towing a Camper with Weight Distribution
    The Coil SumoSprings Custom Helper Springs # CSS-1125R would be an excellent choice for your 2006 Ford Explorer. This product should give your suspension additional support to should reduce the excessive sag you are experiencing. I checked with SuperSprings and the do not recommend you install two of these per spring. One should be sufficient. Some things you should also check are you need to be sure that your suspension components are in good working order and that your weight distribution...

    The SuperSprings Coil SumoSprings, # CSS-1125R, have been confirmed to fit your 2013 Toyota RAV4. I pulled these springs from our warehouse to make a video for you to give you an idea of what they look like. These springs are 6-1/8 inches in diameter. They have an overall height of 2-1/2 inches. The thickness is 3/4 inch and the height of the inner portion of the spring is 1-1/4 inch.

  • How To Prevent Sag On 2004 Honda CR-V With Small Trailer
    The Coil SumoSprings Custom Helper Springs part # CSS-1125R are the perfect option for a 2004 Honda CR-V. They are super easy to install (no tools required) and will do a great job of helping transfer weight from the rear to the front axle which will improve braking and stability. In regards to shifting items on the trailer to lessen the tongue weight, this is not a good option because it will in turn affect the stability and lead to sway which is possible even with an anti-sway bar.

    According to Curt, the # C67JR Class III hitch is compatible with all models of the 2022 Subaru Outback, including your Wilderness model. I don't have specifics about the departure angle, but as you can see in the photo I provided and the linked installation video, when we installed the # C67JR on a 2021 Outback, the receiver tube butted right up against the underside of the bumper fascia. If you measure down 3 inches from the underside of your bumper fascia, that will be the lowest point...

  • Suspension Enhancement Recommendation for 2014 Chevy Impala
    If the wheelchair carrier is only 2 inches off the ground when it is loaded that would most likely indicate that the hitch setup has a pretty nasty downward bend or the suspension is completely maxed out. Suspension enhancement like the part # CSS-1125R (which is a confirmed fit for your 2014 Chevy Impala) will help with the suspension. But you really need to make sure that you aren't overloading the hitch. If you can send me a picture of the setup with it loaded that would help a lot...

  • Choosing Between Coil Sumo Springs and Firestone Coil-Rite Helper Springs on 2012 Toyota RAV4
    A suspension enhancement product like the SumoSprings # CSS-1125R or Firestone Coil-Rite # F4174 are primarily designed to suspend the weight of cargo carried in the vehicle itself. It's not always the best choice for counteracting the vehicle squat caused by the tongue weight of a trailer being applied to the vehicle. The SumoSpring or Coil-Rite can in some circumstances act like a fulcrum, causing the load on the front axle to lighten, which can lead to decreased braking performance and...

The Coil SumoSprings # CSS-1145R have a 1.45" inner wall and are 3" tall and 6.5" in diameter.
