Master The Road
RoadActive Suspension (RAS) is the only rear leaf spring suspension upgrade that converts basic “passive” leaf spring suspension to mechanical “active” suspension. Our system strengthens the rear leaf springs by absorbing and dissipating load force energy, resulting in significantly improved load and road handling without ever compromising ride quality. Add strength and stability without readjustments or maintenance. Master The Road.

Master Squat
The unique design of the RAS kit significantly strengthens and improves the ability of the rear suspension to handle heavy loads, resulting in reduction of rear squat by up to 3-4 inches.
Master Stability
Improve safety and control of your vehicle by reducing sway and body roll with, and even without, a load.
Master Rebound & Hop
Reduce excessive bounce when towing or hauling. Improve axle wrap and wheel hop issues.
Master Ride Quality
Gain unparalleled driving performance with improved handling and ride quality, even without a load. Body roll will be greatly reduced and your vehicle will become considerably more stable and safer, with or without a load.
Master an Easy Install
The kit comes fully assembled out of the box, with easy to follow instructions. Installation is simple taking less than an hour, with no drilling, cutting or welding and once installed requires readjustments.
The active suspension I installed on my F150 is among my top two upgrades that I have done to the truck, and there have been many. The difference it made in the handling and appearance of the truck (eliminated the terrible squat) while towing my wife’s 6,000lb horse trailer is amazing. Can’t imagine using my ½ ton truck to tow without it!

Just installed mine a few weeks ago and MAN it makes a world of difference! For reference I have a 2015 F-150 towing 34' Travel Trailer.

I've had it on my 2013 GMC 2500 for 3 years, works great when towing heavy trailers.

When we bought our horse trailer I immediately knew I needed something to help with the suspension on my truck. I did my research and came across the Roadmaster Active Suspension and decided to try it out.. to say I’m impressed is an understatement.. rides great loaded or empty, stops my truck from bottoming out when loaded heavy and just makes towing a much safer and more all around enjoyable experience.

I installed a set 3 weeks ago. Towed my 5400LB camper and could tell a big difference in handling.

I have had 2 F150's, I put this on both of them. Really makes a difference.

I'm so impressed, well engineered, model specific, fits first time!
I installed it on a 2001 Ram 2Wd, to pull my travel trailer. It performed very well and greatly reduced tail wagging when being passed on the interstate!
The 3100 lb trailer required no sway bars using the Roadmaster Active Suspension. I thought it was pricey at first, then installation was a breeze, after putting it to the test pulling my camper!
I would be happy to recommend it to anyone! It actually works!!

Fantastic product!!!! My 1996 Ram 2500 drives like its brand new!!!!! What a difference!!

Just the road handling after the install was amazing basically feels like it sticks to the road like a sedan instead of a 4wd truck. I originally was getting them for towing but the road manners made them worth the money.

Bought these and put them on my 2014 GMC 1/2 ton crew cab to haul my travel trailer, changed my ride immediately, removed the bounce on bridges and the sway motion. Would recommend to anyone doubting.
