RoadActive Suspension kit includes an easy to install RAS Spring for each rear leaf spring. RoadActive Suspension kits are designed to strengthen the rear leaf springs for towing or hauling while providing same-as or better-than-stock unloaded ride and performance. This 3-in-1 solution works like a helper spring, sway bar and traction bar, at 1/3 the price. Fit-and-forget it install time is approximately one hour.  

RoadActive Suspension provides a 30 day money back guarantee, from date of purchase. However should the kit be returned, it must be re packed in the original packaging with all components included. On orders with free shipping (where shipping was paid for by RoadActive Suspension), refunds will reflect the invoiced amount, minus that shipping cost billed to us by our shipping provider. In addition, the customer will be responsible for the return freight charges.

It works with your suspension — not against it.

Each kit is tailored to your specific vehicle

RoadActive Suspension is uniquely assembled for your model and typically ships within 1-2 business days! RoadActive Suspension is the only suspension upgrade on the market that adds strength to your rear suspension, provides same as or better than stock unloaded ride quality and doesn’t require readjustments or maintenance.

Each RAS kit comes fully assembled out of the box and ready for installation. Follow your application guide that is in the box and you will be ready to test your RoadActive Suspension after an installation as simple as 45 minutes! If you are not satisfied with your RoadActive suspension we offer a money back guarantee.

No Readjustments or Maintenance

We already know what you're going to ask.

No, installing RoadActive Suspension (or any other rear suspension helper) does not automatically void the factory warranty. The Magnuson Moss Act states that it is illegal for a vehicle manufactuer or dealership to void a warranty just because a part has been installed. The manufacturer or dealership may only void the warranty if they are able to prove the aftermarket part caused or contributed damage to the vehicle. Even then, warranty to the impacted component(s) is the only portion of the warranty that may be voided. In this case, all other parts of the vehicle remain under warranty.

RAS uses a variable-rate tension coil spring that attaches directly to your rear leaf springs. It works like a muscle, progressively engaging as load or force is applied. This keeps the leaf springs in an upright bowed position to prevent sag, improve stability, and enhance bounce isolation.

Most applications see a 2–3" reduction in rear squat. The exact amount will depend on multiple factors such as vehicle size, load size, load placement, leaf spring condition, and the tension setting of the RAS.

Expect same-as or better-than-stock unloaded ride with less bounce and more control.

Yes — in as little as 45–60 minutes with jack stands and hand tools. No drilling, no air lines, no maintenance.

Airbags add complexity, cost, and ongoing maintenance. Other helper springs only address sag and can compromise ride comfort.RAS is 3-in-1:it controls squat, reduces sway, and improves traction — all with zero maintenance.

Excellent upgrade to the standard rear suspension on my 2024 Ford Ranger. When towing, it reduced squat and smoothed out the road. When not towing, the ride is so solid and positive, especially on curves at highway speeds. I purchased kit #4515 R.

I added a 200# stainless steel topper to my 2024 Ford Ranger XLT FX4. This leveled the truck and then caused it to sag when towing my camper, especially with gear in the bed. I also noticed a bouncier ride and body roll with the weight of the topper. After a lot of research I settled on RAS and glad I did! Immediately got the rake back, a more planted ride, and no more body roll. I love it!

I installed the kit for my 2025 Ranger xlt and it went on easily, it did only include one of the fittings to adjust the brakeline position, but apparently ford changed the position because there was no interference and I didn't need it. It took me about an hour and a half to install and should help with my loading.

I ordered it for my 2020 Ford Ranger. Driver side was alittle difficult to put the hook end through the shackles and leaf spring. I had to unscrew the hook end to eliminate the assembly to shorten to get the angle needed to fit through. But passenger side didn't need to fit right in. I installed a Decked system in my truck and put tools in it and it caused a 3/4" sag compared to the front. (I did install a leveling kit years ago.) After I installed the Roadactive suspension it leveled it perfectly and made the truck feel more stable and planted in the rear.

I recently installed a RAS System on my 2020 Ford Ranger Supercab. The install was easy and straight forward. The hardest part was getting the hook part around the bushing, but you just have to work it in place. It gave me 1” of lift and I installed new shocks as well. This greatly helped out for when I tow my utility trailer. I have to get into a steep driveway and was occasionally scraping the jack on the trailer, but no longer after the RAS. I would recommend it as a great cost effective way and quicker instal then buying new leaf springs, which was the route I was going until multiple people recommended RAS.

Easy to install. Took squat out of Ranger Tremor that has moonlander camper topper on it Check the tools needed. They may be larger than you have at home.

Ford Ranger 2019-2026

Night and day. 2019 ranger fx4 has soft suspension. Good off road but boat like going down state hi ways or towing my camper. The bouncy truck is gone. Way better.

Ford Ranger 2019-2024

Love the kit. It's a great help with the bouncing on my truck/camper. Now don't get the idea it won't bounce because that would be a lie. But my setup went from bouncing for very to just a bounce or two. No more feeling like someone was trying to jerk the truck out of my hand to just a gentle bounce or too. Fantastic improvement. We'll worth the investment. Thanks for a great product.

Ford Ranger 2019-2026

Added to 2026 Ford Ranger. Raised rear end about 1&1/2 inches. Simple install. Was able to install them without removal of rear tires. Primarily use for towing boat and has helped with less drop and sway.

Ford Ranger 2019-2026

Seems to have added more bounce on the front of my truck on concrete roads. I have it on a 2025 Ford Ranger lariat. The truck didn’t seem to bounce as much as it does now on concrete roads but other than that on smooth roads and blacktop ride very well definitely like it on the truck. It’s not towing.

Ford Ranger 2019-2026

No more headlight high beam warnings from oncoming traffic. Yay!

Ford Ranger 2019-2024

Great product, easy to install and adjust. The only complaint I have is the rattle it makes over even small bumps and roadway roughness.

Ford Ranger 2019-2024

So far has been great. The 4 star rating is only because I have not been able to tow my 4k lb. travel trailer since I installed the RAS system. The RAS system did raise the back of my truck about 1 inch, which I expected. Overall the handling has improved which is surprising, as my 2024 Ranger was the best handling vehicle I have ever owned. Now it is even better. Thanks RAS for making such a quality product. I expect when I do tow my trailer I will be just as pleased.

Ford Ranger 2019-2024

Kit arrived with one brake line retainer strap, two were needed. I replaced the strap with two quality stainless steel rubber coated electric retainer straps. The included strap presized mounting hole was too small for OEM retainer screw and had to be drilled to the correct size if it was to be used. The bolts and hardware was lightly corrosion treated cheap Chinese crap, it should all have been stainless steel. I pulled my 19ft trailer with the springs set at +25% and it was a vest improvement in tongue weight management. The RSA system is a good system but would benefit from better stainless steel fixtures to endure the harsh midwest environments. I replaced my WDS hitch with RAS and I think it is a much better system to control sway and rear suspension dip. I would not have bought the RAS if it was not made in the USA. Good job RAS.

Ford Ranger 2019-2024

So I put the RS kit on my 2024 Ford Ranger not so much to lift the load but more to help out the shocks when I’m towing my boat where once I hit a bump in the road and things start bouncing a little bit these help immensely and controlling the after bounce on Highway two in Washington state and also on a Ford Ranger 2024. The shock mounts are on the outside of the frame rails, and the brake lines are reversed from the 23 and earlier on this where they are mounted onto the axle so you don’t have to change or lower your brake line but because the shocks are on the outside of the frame, the passenger side mount you’ll wanna put the hex head to the outside, which will give your shock a lot more room to work instead of having the nut on the outside, which could possibly hit the shock. Otherwise the system is great that works exactly what I thought it would do. I said it for the 25% and I’m very very happy with it.

Ford Ranger 2019-2024

I have a 2019 Ford Ranger and bought the RAS kit because of floating in the rear end and to help with towing, absolute night and day difference. I feel so much more stable while towing and just general stability, without sacrificing ride comfort. 10/10 recommend the upgrade if you’re looking to beef up your rear end.

Ford Ranger 2019-2024

I have a 2023 Ranger XLT 4x4 and for the life of me I can not get the hook part over the back shackle as indicated in the instructions. I'm afraid I'm going to have to drop that whole back bracket to get it to slide on, and even then I'm not sure it will fit I need help and answers because I have trip coming up in May and I pull a 33' Forest River Prime Time Avenger with GVWT 6300 so please assist in anyway you can

Ford Ranger 2019-2024

I started as a someone that saw the ads and videos, but never thought they would be all that they claimed to be. And they aren't..... they are better! I put a set on my 2007 Ford F250 diesel. I tow a 12K and 15K pound trailer regularly and it resolved my sag and sway almost completely. It rides and drives just like factory when empty, but ready and waiting when needed. I love this system so much, I ordered a set for my new 2024 Ford Ranger before I even received the truck. It does everything it does for my F250 in a smaller package. I will not own another truck without a RAS!
