Supports Heavy Loads to Reduce Squat and Improve Stability

While the 2015-2023 F150s may be able to tow and haul extremely impressive loads, you can start running into squat and stability issues long before you hit your F150's GVWR, GCWR, or Payload capacities. That's where the RoadActive Suspension for the 2015-2023 F150 RWD comes into play. The RoadActive Suspension (RAS) System gives your F150 additional load support capability and greatly reduces rear-end sag so that you get improved loaded handling and stability. The RAS System for F150s consists of a pair of specially-designed coil spring dampers that easily install over your truck's factory leaf packs in almost no time at all. The RoadActive RAS Standard System was specifically designed to help compensate F150s that sag roughly 2-3" when under load and also help reduce the chances of axle wrap and even save wear and tear on your rear tires all in one place.

Features Unique Variable-Rate Coil Springs with Bolt-On Brackets and Hardware

The RoadActive RAS System was carefully designed to easily install over your F150's stock leaf springs while being extremely strong so that they can handle nearly any towing application. The RAS is built around unique variable-rated coil springs that work by keeping the factory leaf springs in a bowed position and taking up load so that the stock leaf packs don't have to. The end result is that your leaf springs are doing less work and don't suffer from as much sag when you're towing heavy. The RAS mounts to your F150's leaf pack using a combination of a adjustable axle brackets and a eye bracket for the rear of the factory leaf springs. The entire RAS installs over your F150's factory leaf springs without the need for any permanent modifications to your truck and comes with all the hardware you need to get the RAS up and running. RoadActive even backs their RAS system with a 5-year limited warranty.
