Rear Suspension Support

Towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


Installed spring when it is not compressed

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.


Installed spring when it is compressed

The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.


The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.


Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).


SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.


The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

  • Are SumoSpring Solo Custom Helper Springs A Fit For A 2025 Chevy Silverado 1500 ZR2
    Hi Edward, The SumoSprings Solo Custom Helper Springs # SS65FR is listed as not a fit for Trail Boss or ZR2 models so you would want to swap out those jounce springs for the SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA28. This would sit over the factory leaf springs and only engage as weight is added to the rear suspension, which will prevent a stiff ride when you're unloaded. The other jounce spring options for your Silverado are all waaaaaay too high in capacity...

  • Best SumoSprings For 2024 Chevy 1500 Pulling Trailer With 650 lb Tongue Weight
    Hello Bryan, thanks for reaching out. If the total tongue weight of whatever you are hauling is around 650, I recommend going with the 1,000 lb SumoSprings part # SS65FR. This will give you the support and stability you are looking for without making the ride too rough. Just keep in mind these will not work with the Trail Boss or ZR2 models. Or on models with adaptive ride control. You could use the 1,500 lb and they would give you support but you would be adding additional capacity that...

  • What Timbren Rear Suspension Springs Fit a 2024 GMC Sierra 1500?
    The Timbren Suspension Enhancement System # T28MR is the kit which will fit your 2024 GMC Sierra 1500. Do understand this is a very heavy duty spring with a weight capacity of 8,600lbs. This will most likely give you a less than desirable ride quality. Instead I recommend checking out the SumoSprings in a 1,000LB # SS65FR or 1,500LB # SS45FR capacity. These are much more inline with the weight capacities of your Sierra. And as these are a progressive material it will not be as harsh of...

  • Comparing The SumoSprings Solo Customer Herlper Springs # SS45FR And # SS65FR
    The SumoSprings Solo Custom Helper Springs # SS45FR and SumoSprings Solo Custom Helper Springs # SS65FR both have the same fitment but have different weight capacities. The # SS45FR is rated for 1,500lbs while the # SS65FR is only rated for 1,000lbs.

  • Is There A Spacer Kit For SumoSprings Solo Custom Helper Springs To Fit A 4" Suspension Lift
    SumoSprings Solo Helper Springs unfortunately aren't really designed for lifted trucks and the manufacturer only recommends using up to a 2" spacer so the # SS65FR isn't going to be the best solution for you. Instead you'll want to go with an option like the SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA28. This attaches to the leaf springs and provides extra support for your suspension to prevent sag and reduce sway, without compromising ride quality.

  • Recommended Maintenance Free Suspension Enhancement for 2024 Silverado 1500
    For a maintenance-free suspension enhancement option on your 2024 Silverado I recommend the SumoSprings Solo Custom Helper Springs # SS65FR. These have a weight capacity of 1,000 lbs, a microcellular urethane construction, and a lifetime warranty. The SumoSprings will help keep you level, reduce sway, and absorb shock when you're towing or hauling heavy loads. They also won't have a harsh impact on your unloaded ride quality like some other options do. Keep in mind, these will not work...

  • SumoSpring Recommendation for a 2022 Chevy Silverado 1500 LTD Trailboss
    For your 2022 Chevy Silverado 1500 LTD Trailboss you can either use the SumoSprings # SS65FR which is rated for 1,000 lbs or the SumoSprings # SS45FR which are rated for 1,500 lbs. I honestly just recommend going with the higher rating. SumoSprings is known for retaining the great OEM ride quality of trucks so having the extra capacity just means you'll get more support if you ever need it. Please note that a suspension enhancement system will only add some help to a current suspension...

  • How Much Space Should There Be Between SumoSprings And My Axle Pad On 2021 Chevrolet Silverado 1500?
    With the SumoSprings Solo Custom Helper Springs # SS45FR or # SS65FR installed on your 2021 Chevrolet Silverado 1500 with no additional cargo weight you will see 1/2" of clearance between the spring and your axle pad. This allows for you to have a comfortable ride when you are unloaded. SumoSprings does include an additional 1" spacer and longer mounting bolts with both kits that will allow you to add preload to your springs if so desired. This comes in handy if you always have additional...

  • SumoSprings for 2021 Chevolet 1500 Trailboss w/ Factory 2 Lift
    I reached out to my contact at SuperSprings to determine the best helper spring for your 2021 Trailboss truck. You were comparing the SuperSprings # SS45FR with the SuperSprings # SS65FR. These helper springs will have about a 1" gap before they contact the suspension and then they will compress and further support your load, so there will still be just a little bit of squat at the back of the truck. The # SS45FR springs are bigger and will support more, whereas the # SS65FR springs are...

  • Comparing SumoSprings Solo Custom Helper Springs for a 2022 Chevy Silverado 1500
    There are two SumoSprings Solo Custom Helper Springs for a 2022 Chevrolet Silverado 1500, part # SS65FR which has a 1,000 lb weight capacity and part # SS45FR which has a 1,500 lb weight capacity. The lower rated option rides smoother whereas the higher rated option provides more support. The correct one will come down to what you're towing or hauling. If you have a heavy trailer over 10K then go with the higher rated part # SS45FR but for most others under this use the lower rated part...

  • Using SuperSprings SumoSprings On a 2021 GMC Sierra 1500 With Weight Distribution
    Yes, the SumoSprings Solo Custom Helper Springs # SS65FR will help with the bouncing that you are getting with a weight distribution hitch on your 2021 GMC Sierra 1500. The SumoSprings are progressive so they will help to absorb the bounce that the suspension is having when you go over bridges. You may notice a firmer ride when you do not have additional loads being carried as the suspension compresses due to large pot holes. The SumoSprings can be installed before or after the weight...

  • What is Difference Between SumoSprings Kits SS45FR and SS65FR that Fit 2021 Silverado 1500
    There isn't an actual height difference between the SumoSprings Solo part # SS45FR and the # SS65FR that fits your 2021 Chevy Silverado 1500. The difference is related to the capacity. The 45 has the higher 1,500 lb capacity and the 65 has a 1,000 lb capacity. Both of these fit the Trail Boss models without any additional spacers.

  • Recommended SumoSprings For 2021 GMC Sierra 1500 Carrying 1000lb Golf Cart In Bed
    For your 2021 GMC Sierra 1500 carrying a 1000lb golf cart I recommend the SumoSprings Solo Custom Helper Springs # SS45FR (black) which have a 1500lb load leveling capacity. While this is a little more than you need for your golf cart, this will be a slightly stiffer spring so it will do better at preventing sag with the golf cart loaded than the # SS64FR (blue) you were looking at with a 1000lb capacity. Since these springs are so much softer than Timbrens, going with the 1500lb springs...

    The SumoSprings Solo Custom Helper Springs - Rear Axle # SS65FR are confirmed to fit your 2021 GMC Sierra 1500 AT4. However, I would not recommend them. Since the AT4 has a 2" lift, the SumoSprings would likely be ineffective unless you are experiencing a lot of sag under a heavy load. They already require some sag before they engage, so the additional lift will increase the distance they need to move before they start to work. Instead, I recommend the RoadActive Suspension Custom Leaf...

  • Will SumoSprings Help Sag With 2020 GMC Sierra 1500 But Keep Ride When Not Towing
    The SumoSprings will do a fantastic job helping eliminate sag when you are towing with your 2020 GMC Sierra 1500 Denali, and won't affect your smooth ride when you are not towing. The reason is, when installed, if you aren't towing there will be a space between the SumoSpring and your axle and the spring won't come into contact with it. The only time you might feel it slightly is when going over a particularly large bump, but otherwise it won't be noticeable. There are two SumoSprings...

    The SumoSprings Solo Custom Helper Springs item # SS65FR are designed to do exactly what you talked about. These springs have progressive load control that compress according to the weight of your cargo. This will eliminate the sag you get in your rear end when you are hooked up to your trailer. When the rear end of your GMC is not weighted down there is a space between the helper springs and your axle. This will enable your ride when not towing to stay comfortable and smooth. You won't...

  • Will The Timbren Suspension Enhancement Fit a 2024 Chevrolet Silverado 1500 ZR2?
    While I can confirm the Timbren Rear Suspension Enhancement # T28MR will fit your 2024 Chevy Silverado 1500 ZR2, I would be hesitant to put such a heavy spring on your truck. I would personally select the SumoSprings # SS65FR as these will actually help to absorb road shock where the heavy Timbren's would transfer it to the truck. I only like using Timbren springs on very heavy duty applications such as trucks with a plow or work box in place of the bed.

  • Suspension Enhancement Options for 2008 Kodiak C5500 Motorhome
    Although they are for the front axle, the SumoSprings # SSF-281-47 are confirmed to fit your 2008 Kodiak C5500 Motorhome. Unfortunately, for the rear axle the only comparable option is the Timbren Rear Suspension Enhancement System # TGMRC55. There is a cost difference, but you have to consider that the # SS65FR you were looking at is for a truck and not a motorhome. Also, rear SumoSprings for your motorhome would likely have a different price point compared to the front. If you compare...

  • Troubleshooting Curt TruTrack Not Leveling Truck After Installation and Maximum Adjustment
    It sounds like your system may be overloaded. The first thing I would recommend is finding your actual tongue weight. Your Curt # C79JR (17600) has a tongue weight range of 800-1,000 lbs. If your tongue weight is around 1,000 lbs you're already at the maximum, or possibly more which would make the system ineffective. I recommend using the # e99044. Another possibility is your shank rise/drop is not enough. I'm not sure which one you have, but the difference between the height of the top...

These will install completely different from each other and there will no issues with interfering or anything like that.
