Original (RAS®) RoadActive Suspension 4611-HD | Fits Chevy/GMC 1500 1990-2026 | Chevy/GMC 2500 & 3500 1973-2010

Put this on a 2020 Silverado 1500 Custom Trail Boss. Double Cab, 4.3, 6L80, 4x4. To preface, all hardware comes loosely installed. I had no missing parts. It’s worth the money if you don’t want to go with helper bags. It’s a poor man’s overload spring and is worth every penny. No squat. If you’re towing ANY kind of trailer, especially with the trail boss suspension, buy it. If you don’t have a sway bar, buy it. If you DO have a sway bar. Buy it. First off, this was extremely easy to install. The instructions were clear and concise. I was done in 30 minutes. Ride quality with no trailer is unaffected (weird, but I’ve put thousands of miles on this truck since install), and the rear ride height was raised by 1”. Even hauling a single axle enclosed trailer, you can tell the difference. It’s soft when you need it to be. It doesn’t squat under load. It does the job it’s intended for, and does it extremely well. I combined this with the Hellwig sway bar kit, and let me tell you…Chevrolet needs to pay attention and take notes.

I bought these in place of air bags that I was looking at. Im very happy with the results, especially at a third of the cost. Took about 1 hour to install with not hitting it hard. Takes a little to get used to adjusting but it's very easy to do.

Arrived quickly and came with a sticker! Installed these on my 05 Silverado 1500HD. They were easy to install in a short amount of time with minimal tools. They lifted the truck a good bit in the rear with them on the 40% setting but not complaining because it sits perfectly level. Unloaded ride quality is great, truck rides smooth and handles well in corners and it has less sway than before. Im excited to see what happens when we load up the camper and the car hauler.

The road active suspension was easy to install and it made the world of difference when I hooked onto my travel trailer to my half ton pick up truck you can set it in two settings, stiff or medium. The ride of the vehicle is so much smoother.

Easy to install and works great. Towed my rv trailer home and my truck pulled great. Great product, would recommend.

I decided to purchase this system because my Chevy 1500 LT does squat a little bit even though the tongue weight of my travel trailer is below the truck's conventional towing weight limit (930lbs). It did lift the truck by 4 inches because I set it to the max capacity and there is no more squatting. Towing my 8,000 pound travel trailer was a piece of cake and the system didn't affect the ride when I'm not towing!

Adds the strength needed for more weight and nearly eliminated dangerous sway!

It works and very easy to install

RAS has been installed, so far everything is excellent. No more air bag hassles. RAS is maintenance free.
