Radius Arm Link Kit with Track Bar

Radius Arm Link Kit with Track Bar

Complete DOM radius arm kit with track bar—simplifies link suspension setup and saves space.

Radius arms have long been a go-to for OEM and custom suspension setups, especially when space is limited between the frame rails. By tying the upper link into the lower arm, you eliminate the need to mount upper links to the frame, making it ideal for tight builds with clearance challenges around exhaust, motor mounts, or crossmembers. This kit expands on our long-standing radius arm setup by including a complete track bar system, giving you everything needed to center the axle and keep geometry in check.

Built from heavy-wall DOM tubing with heat-treated heims, bushings, and adjustable brackets, this kit is designed for serious trail use and long-term reliability. It includes both inside and outside frame options for the track bar, centered or offset axle brackets, and adjustable axle-side link brackets to fit your setup just right. Strong, simple, and proven.
