When a your Rover is lifted, the front caster angle shifts with it. At factory ride height the steering geometry is dialed in from the factory, but raise the suspension and that angle changes enough to introduce vagueness, reduced self-centering, and unpredictable handling at speed. The Lucky 8 Terrafirma Caster Corrected Radius Arm Kit is purpose-built to correct that problem in one complete, hardware-ready package. Available in 3-degree and 6-degree configurations to match your lift height, this kit brings together Terrafirma's caster corrected front radius arms, a full matched set of Terrafirma polybushings, and all required mounting hardware so everything needed for the installation arrives in a single box. The 3-degree kit (TF508PBK) is the correct choice for Rovers running a suspension lift of 50 to 75mm (2 to 3 inches). The 6-degree kit (TF528PBK) is built for builds with lifts exceeding 75mm (3 inches), where a 3-degree correction would leave the geometry under-corrected and the steering still compromised. Both kits use the Terrafirma arms finished in Terrafirma's signature gold powder coat and engineered to accept the polybushings included in each kit that replace the factory rubber compound with a more durable polyurethane formulation that resists compression set and handles the increased suspension loads that come with a lifted build. Lucky 8 assembled these kits because sourcing arms, bushings, and hardware separately is a time-consuming exercise that too often leads to mismatched specifications and delayed installs. This package eliminates all of that. Select your configuration using the dropdown, and everything ships together, matched and ready to go.
