Unlike the COR-4805015 conversion add-on (which upgrades an existing long arm system to 3-link), this kit is the complete front-half system — it includes the weld-on 3-link upper arm mount brackets, double-adjustable lower control arms, upper 3-link arm with LH\/RH threads, and all hardware. The 3-link front geometry eliminates the binding characteristics of the factory 4-link upper arm arrangement at extreme suspension travel, providing maximum axle articulation for hardcore off-road use. The frame-end joints are Currie Johnny Joints — 40° of unrestricted movement with Tough 88 urethane casing for shock absorption and NVH isolation. The axle-end joints are GIIRO dual-durometer bushings — maintenance-free, self-centering, and NVH-isolating. The double-adjustable lower control arms allow precise geometry tuning for caster and arm length. The upper 3-link arm uses LH\/RH threads for quick length adjustment without removing the arm. Installation requires welding the 3-link upper arm mount brackets, fabricating a custom exhaust, and installing a front CV-style driveshaft with SYE kit. The Clayton D30 front truss is highly recommended. Aftermarket axles require a truss compatible with your specific axle. Lifetime warranty on all control arms.
