The Lock-N-Load solves the problem of the inherent bind of Radius Arm systems.

When a solid axle articulates by dropping one wheel while raising the other, one side of the solid axle will rotate forward and the other side backwards; the short length fixed control arms on a radius suspension limits this and puts a tremendous strain on all the related components.

  • Dual-Purpose Control Arm
  • "Lock It" for Daily Driving
  • "Load It" for Trail Articulation
  • Built with Duroflex™ Joints
