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.

Very easy install. Fixed the sag on my 2014 F250. Improved the rice on rough country roads.

2015 f-350 crew singles - Gives about a 2" lift with the thicker spacer. Squat with a loaded trailer is very minimal. Unloaded ride is very smooth. The install was pretty easy - but removing the overload spring was a real pain. Overall installing the RAS alone was only 35 to 40 minutes, including tire removal and reinstall. I managed to break off the brake line to the caliper while removing the overload spring (clamp slipped). Everyone who rode in my truck before the RAS and after has mentioned that it is much smoother both unloaded and loaded. I'd do it again, just plan on extra time if you have to remove the overload spring and have a good set of c-clamps.

i didn't exspect them to makes the truck more stable when not carring a load.also i used the 2 mm shim to ajust them but when i put the 5th wheel on the truck it madethe truck take bumps like i had no spring on the truck. i'm going to back them off to the 1mm setting.

It really stabilized my 2014 F150 when towing my 32ft trailer. In conjunction with the Bilstine 5100 shocks. I’ll never have a truck again without this set up. Totally worth the investment.
