A High Quality Part

For More Than Just Squat

Using high quality components proven to last, pickup owners enjoy the seamless blend of improved load handling, performance, ride quality and enhanced overall performance at all times.

Celebrating 25 Years
  • RAS offers a more complete solution, where enhancing stability, reducing rear squat, dampening excessive rebound, improving performance, and providing same-as or better-than-stock ride is just as important as reducing rear squat.

  • While RAS can strengthen the rear suspension by up to 50% in a progressive manner and can improve the way your truck handles loads; it and no other suspension upgrade can increase the manufacturer weight ratings.

  • From a fitment standpoint, RAS often fits lifted trucks without an issue. Before ordering for your lifted truck, be sure to check your suspension for possible obstructions. If there appears to be an issue please contact RAS directly for assistance.

  • Yes! While RAS is geared towards improving overall load handling, stability, and performance without hassle; RAS will also help reduce rear squat by up to 2-3 inches.

Just put mine on my 1500 Chevy, install was pretty dang easy. My truck rides great and pulls my trailer much better. Less sway and squatting.

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.

I ordered these for my 2008 Chevrolet Silverado 1500.. There we're incredibly easy to install took about an hr. give or take. No more sag when I tow my travel trailer... I would definitely recommend these....

RAS is an incredible system for handling my camper. However, I havnt had them installed for more than a little over a month and they are already squeaking. Kind of annoying to hear, especially on a brand new truck.. other than that. Works well. Just wish it didn’t squeak..

This is awesome! My RV was a little too heavy and was forcing the back of my truck down, these easily corrected that sag by raising my truck two inches (could've gone more) and provided a nicer ride even without towing the trailer. Very easy to install, although I've watched them be installed many times on YouTube prior to installing mine.

Put this on a 2020 Silverado 1500 Custom TrailBoss. 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.
