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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eLucky 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.

If your Rover is running a suspension lift of 50 to 75mm (2 to 3 inches), select the TF508PBK 3-degree kit. If your lift exceeds 75mm (3 inches), select the TF528PBK 6-degree kit. Using the 3-degree arms on a larger lift will leave the caster angle under-corrected and the steering geometry still compromised.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWhat is included in each kit?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach kit contains a pair of Terrafirma caster corrected front radius arms in gold powder coat, the full matched set of Terrafirma polybushings sized to the arm specification, and  mounting hardware. Nothing additional needs to be sourced to complete the installation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWill this kit fit my pre-1994 Defender or pre-1986 Range Rover Classic?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBoth the TF508 and TF528 arms are designed around the 44mm wide bush specification, which applies to Range Rover Classic and Discovery 1 from 1986 onward and to Defender from 1994 onward. Defenders built before 1994 and Range Rover Classics built before 1986 used a narrower bush specification and are not compatible with these kits.\u003c\/p\u003e","brand":"Lucky8 Off Road ","offers":[{"title":"3-Degree Radius Arm \u0026 Poly Bush Kit","offer_id":54029369376981,"sku":"TF508PBK","price":1088.32,"currency_code":"USD","in_stock":true},{"title":"6-Degree Radius Arm \u0026 Poly Bush Kit","offer_id":54029369409749,"sku":"TF528PBK","price":1088.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2178\/4267\/files\/SHOPIFY_b1efa864-97cf-40a4-8aae-ad7e0f89e490.png?v=1781200255","url":"https:\/\/lucky8llc.com\/products\/lucky-8-terrafirma-caster-corrected-radius-arm-poly-bush-kit","provider":"Lucky8 Off Road ","version":"1.0","type":"link"}
