The kit includes a three-piece crossmember and upper and lower adjustable control arms. The frame-end joints are Currie Johnny Joints — a 3-piece design with a steel ball, \"Tough 88\" urethane casing, and housing that provides 40° of unrestricted movement with the shock absorption and NVH isolation that heim joints cannot provide. The axle-end joints are GIIRO dual-durometer bushings — a softer outer durometer for NVH isolation and a stiffer inner core for lateral load resistance, maintenance-free and self-centering. The longer arm geometry reduces suspension angles at lift height compared to short arm geometry, resulting in a smoother on-road ride, greater off-road articulation, and reduced wear on related components. A front CV-style driveshaft is required for this conversion and is sold separately. Year-specific exhaust modifications are required on 2010–2018 models — see installation notes for details by model year.

Also confirm you have a front CV-style driveshaft sourced before ordering — this kit cannot be driven without one after installation.\u003c\/blockquote\u003e","brand":"Clayton Off Road","offers":[{"title":"Default Title","offer_id":51651332604225,"sku":"COR-4808122","price":1677.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/COR-4808122_1-COR.jpg?v=1776528921","url":"https:\/\/obsidianforgedautosupply.com\/products\/clayton-premium-front-long-arm-upgrade-kit-jk-cor-4808122","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
