Heavy Duty "HD" Kits for 3/4 & 1 Ton PickUps

Welcome to Roadmaster Active Suspension

Welcome to the unique world of Roadmaster Active Suspension (RAS), the ultimate assist for vehicles with rear leaf spring suspension. RASis the only suspension upgrade that converts basic “passive” leaf springs into mechanically “active” suspension. A system that instantly absorbs and dissipates load force energy resulting in significantly improved vehicle stability, balance, traction and control, with or without a load. Roadmaster Active Suspension adds critical strength to leaf springs but WILL NOT compromise ride quality. The patented design eliminates bottoming out, axle wrap and wheel hop, greatly improves road handling by reducing sway and dangerous body roll on cornering, and strengthens the rear leaf springs for towing or hauling maximum loads with maximum safety. Vehicles and fleets that consistently operate under load benefit from improved fuel efficiency, vehicle safety and load carrying capacity as well as reduced driver fatigue and extended tire and suspension component life. RAS is a simple retrofit to most every pickup truck and van with rear leaf springs, with up to a 1 1/2 ton capacity, and once installed no adjustments or maintenance is ever required. Installation is only about a 30 min.process.

  • Light duty Pickups
  • 1/2, 3/4 to 1 ton Pickups
  • 1/2, 3/4 & 1 ton Cargo Vans

    Unbelieveable ride improvement

    Posted by John Wilson on 20th Jan 2017

    I own a 2003 Dodge 3500 with Cummins, straight body with a dual disc clutch and regularly pull 12,000 to 20,000 lb loads locally and across the country. I added the Roadmaster HD and have been completely shocked at how much better pulling performance is now.

    Axle wrap seems to have stopped, passing semi trucks no longer results in being knocked around the road by air, the truck doesn't squat with a load, handles curves while loaded better than previously while empty. I pulled a 24' cargo trailer on a 300 mile trip and even loaded with several tons of weight, I couldn't feel the trailer.

    Great product. Install was very easy. The first side took about 1 1/2 hours and the second side took 20 minutes. Clear instructions were included and so long as you READ the instructions you shouldn't have a problem to install. Basic tools and a torque wrench were all that was needed.
