Rear Suspension Support

A heavy rear load can cause 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.

  • Choosing Between the 1,000 Lb and 1,500 Lb SumoSprings for a 2019 Ford F-150 4x4
    I recommend the SumoSprings Solo Custom Helper Springs part # SSR-117-47 instead of part # SSR-117-40 for your 2019 Ford F-150. In regards to the SumoSprings, you will always want to have a safety margin and the above will be perfect for your setup. The springs have a progressive load rate so the 1,500 model with 850+ lbs will have a smoother ride than the 1,000 lb model with 850+ lbs. In regards to unloaded ride quality, there should be no affect on this for the exception of going over...

  • Best SumoSprings For 2020 Ford F-150 4WD For 5th Wheel Towing
    The two SumoSprings you mentioned are the same but for their weight capacity of 1,000 lbs vs. 1,500 lbs; so for your 2020 Ford F-150 4WD that is towing a 5th wheel trailer the best option is definitely going to be the 1,500 lb spring: - SumoSprings Solo Custom Helper Springs # SSR-117-47 The reason is, since you have a hitch weight of over 1,300 lbs, you'll need the spring with the right amount of support, and the 1,000 lb option isn't quite enough as they will constantly be compressed...

    The 1,000 pound capacity SumoSprings Solo Custom Helper Springs # SSR-117-40 for 4 Wheel Drive and # SSR-116-40 for 2 Wheel Drive referenced in your question will offer a smoother empty ride in your 2020 Ford F-150 than a higher rated alternative spring. It is important though to keep in mind that any weight coming from behind the rear axle of your F-150 and from the trailer hitch itself should also be considered when choosing a suspension enhancement system, as this will be included to...

  • Recommended Suspension Enhancement for 2016 Ford F-150 4x4
    The RoadActive Suspension Kit # RAS3611-Y is the correct fit for your 2016 Ford F-150 4x4. This is a mechanically active system designed to eliminate the bounce you are experiencing. It will allow adjustment for the best fit on your truck but doesn't require any additional adjustment so it doesn't need to be changed for when loaded or unloaded. The SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-117-47 are also a great option to eliminate the bounce by helping to level your load...

  • Suspension Enhancement for 2018 Ford F-150 With 6 Inch Lift
    I am not familiar with the Pro Comp kit; I did look it up and from the installation manual it seems like all parts of the rear suspension were affected. Can you confirm if there is any type of interference with the leaf spring? Your only option is going to be a kit that attaches above the factory leaf spring but if there is interference of any kind then it would not be a fit.

  • Best Towing Enhancements for a 2013 Ford F-150 with 5.0L V8 Engine
    If you are looking for performance enhancements, I recommend using the Edge EvoHT2 Hand-Held Performance Tuner part # EP16040. This tuner can provide you with a boost in horsepower up to 24 HP and torque up to 24 TQ. The towing tune built into the device will adjust shift points for prolonged transmission life and maximize fuel pressure for increase fuel economy. If you are looking for suspension enhancements, I recommend taking a look at the SumoSprings Solo Custom Helper Springs part...

  • Comparing SumoSprings, SuperSprings, RAS, and Air Bags for 2019 Ford F-150
    The RoadActive Suspension (RAS) Custom Leaf Spring Enhancement Kit part # RAS3611-Y is what I recommend for a 2019 Ford F-150. The RAS Kit unlike the SumoSprings Solo Custom Helper Springs part # SSR-117-47 will engage right away so you don't have to reach a threshold before the support kicks. Therefore, they will do a better job of reducing sag/squat. In comparison to the SuperSprings Custom Suspension Stabilizer and Sway Control Kit part # SSA28, The RAS Kit can be adjusted and offers...

  • Can the Hellwig EZ-990 and the Sumosprings Solo Helper Springs Be Used Together
    G, Yes both the Hellwig EZ-990 Helper Springs # HE67FR and the SumoSprings Solo Custom Helper Springs # SSR-117-47 can be used together. The SumoSprings will replace the factory bump stops, and the Hellwig bolts above the factory leaf springs so the two won't interfere with each other.

  • Best Way To Enhance A 2016 Ford F-150 Suspension Without Affecting Ride Quality.
    If you're wanting to enhance your suspension on your 2016 Ford F150 and keep your ride quality, air bags are not the solution. If you wanted to go with the bags anyway, you would need to get the LoadLifter 5000 # AL88385 as we do not sell the LoadLifter PRO. Here is a compressor system that will work # AL25572. If you wanted to go a different route and affect your ride quality less when not hauling, I would get the RoadActive Suspension Enhancement System # RAS3611-Y. This is adjustable...

  • Recommended Suspension Enhancement for 2020 Ford F-150 Crew Cab 4x4
    The Timbren Suspension Enhancement System # TFRTT1504E is a confirmed fit for your truck. With a 1,100 lb tongue weight trailer, this system will help to keep the rear end from squatting and your headlights from being too high to see the road as intended. These will act as a shock absorber as well as helping to stabilize your truck when under load. These spring are made for severe service vehicles like tow trucks so I don't recommend then for your truck as they can actually cause your truck...

  • SumoSprings Custom Helper Springs With RoadActive Suspension On a 2019 Ford F-150
    The SumoSprings Solo Custom Helper Springs # SSR-117-47 can be used with the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-Y on your 2019 Ford F-150. These 2 systems mount in different locations so they will not interfere with each other. The SumoSprings Rebel Custom Helper Springs # SS95QR cannot be used as they mount on the same point around the leaf springs as the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-Y.

  • Will SumoSprings and Rear Shock Upgrade Work Together
    You will be in great shape with these two working together the SumoSprings Solo Custom Helper Springs part # SSR-117-47 doesn't really negatively effect suspension travel as it is pretty soft to start and then stiffens when compressed. Unlike the harder Timbren counterpart you will be very happy with the way these work.

  • Rear Helper Springs for a 2012 Ford F-150 4x4 and Forest River Stealth Model 1913
    Timbren rear helper springs # TFR1504D for your 2012 Ford F-150 4x4 will definitely help with the sag you are experiencing when towing your Stealth toy hauler. But when not towing or carrying a load in the truck bed you will likely experience a stiffer ride, more jarring on bumps than the stock suspension. For a similar option that features a softer spring style we have SumoSprings # SSR-117-40 rated at 1,000 pounds, or # SSR-117-47 rated at 1,500 pounds. These springs will have more give...

  • 2018 Ford Raptor Towing Boat Trailer With Weight Distribution System
    Your 2018 Ford F-150 Raptor is rated for 6,000 to 8,000 lbs towing capacity so you will want to make sure your specific vehicle is rated to tow the boat and trailer you desire. To use a weight distribution system on a boat trailer, you need an adapter for the pole tongue of your trailer. I recommend the Pole-Tongue Adapter for Equal-i-zer Weight Distribution Systems # EQ95-01-5950 along with the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control - 6,000 lbs GTW, 600 lbs TW...

  • Comparing SumoSprings Solo and Rebel Helper Springs For a 2019 Ford F-150
    The 3,000lb SumoSprings Rebel Custom Helper Springs # SS95QR will provide more support to reduce the amount of sag that you are having with your dump trailer. Both the Rebel and 1,500lb SumoSprings Solo Custom Helper Springs # SSR-117-47 will perform similarly when your vehicle is not loaded or hauling your trailer. This is due to the progressive tension of the springs. The springs will start off softer and progressively become more stiff as the spring compresses. With your trailer...

  • Recommended Suspension Enhancement For 2010 Ford F-150 Towing Travel Trailer W/ Weight Distribution
    We sure do! For your 2010 Ford F-150 I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-117-47 if your truck is 4WD, or # SSR-116-47 if your truck is 2WD. Both of these options offer 1500lbs of support to your rear suspension, and will help to prevent sag when your travel trailer is hooked up, or when you are carrying a heavy load in the bed. I like the SumoSprings due to them not effecting the unloaded ride quality due to them being progressive meaning they do not...

  • Comparing Blue Vs. Black SumoSprings for a 2017 Ford F-150
    The loaded tongue weight of the trailer will likely be over the 1,000 capacity of the blue SumpSprings part # SSR-117-40 so I recommend the black SumoSprings part # SSR-117-47 for a 2017 Ford F-150. The tongue weight capacity of the trailer (loaded) is the best way to choose between the two.

  • Recommended SumoSprings Custom Helper Springs For 2015 Ford F-150 King Ranch 2WD
    For your 2015 Ford F-150 King Ranch Short Bed EcoBoost 2WD either the SumoSprings Solo Custom Helper Springs # SSR-116-40 or # SSR-116-47 would fit. The # SSR-117-47 is designed for a 4WD truck and would not work on your vehicle. Now the difference between the two options is the # SSR-116-40 has a 1000lb capacity where the # SSR-116-47 has a 1500lb capacity. I recommend going with the # SSR-116-47 as it offers the most support and will not decrease the unloaded ride quality as it is a...

  • Will The SumoSprings Solo Custom Helper Springs Fit a 2016 Ford F-150 With a Leveling Kit?
    The SumoSprings Solo Custom Helper Springs # SSR-117-47 will fit your 2016 Ford F-150 4wd as long as your leveling kit does not alter the rear suspension. Since most leveling kits will only alter the front suspension you should not have any issues.

  • Suspension Enhancement Recommendation for 2015 Ford F-150 Towing Fifth Wheel
    I prefer the rubber spring style of suspension enhancement as it does not require you to inflate air bags at any point which makes it much more convenient. Since the Timbrens have a reputation as being somewhat harsh when the truck is unloaded I really like the SumoSprings like the part # SSR-117-47 which is a confirmed fit for your 2015 Ford F-150.

    For your 2018 Ford F-150 Raptor, I recommend going with the SumoSprings Solo Custom Helper Springs # SSR-117-47. These jounce-style springs feature progressive load control that will provide you with a much smoother ride when compared to the Timbren springs, especially when empty or hauling a lighter load.
