COR-4807013 is the complete front-half Pro Series 3-link kit — it includes weld-on frame brackets, a weld-on 3-link upper mount, double-adjustable lower arms, and a 3-link upper arm. It requires welding, a custom exhaust, a front CV driveshaft with SYE kit, and a D30 front truss. COR-4807002 (this kit) is the 4-link long arm system — bolt-on, no welding, no exhaust modification, no CV driveshaft requirement. If you want maximum front articulation via 3-link geometry and have fabrication capability, COR-4807013 is the correct choice. If you want a significant improvement in front ride quality and articulation over short arm geometry without fabrication requirements, COR-4807002 is correct.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eIf I start with this kit and later want to add 3-link front geometry, what do I order?\u003c\/strong\u003e\u003cbr\u003eCOR-4807015 — the front 3-link conversion add-on. It adds the weld-on upper arm mount brackets and single upper 3-link arm to an existing long arm system, converting the front from 4-link to 3-link geometry. Do not order COR-4807013 after installing this kit — COR-4807013 includes lower arms and frame brackets you already have, which would be redundant.

The front kit's source documentation does not include an axle truss — if you are concerned about front axle tube reinforcement at the control arm mount locations for your specific application, source a front axle truss separately. For Dana 30 front axles, a D30 front truss is available.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDoes this require a front CV driveshaft?\u003c\/strong\u003e\u003cbr\u003eNo — unlike the Pro Series 3-link front kits (COR-4807013, COR-4807015), this standard 4-link long arm kit does not require a front CV driveshaft.

The Currie Johnny Joints, GIIRO bushings, and adjustable upper and lower arms provide the geometry correction and joint quality of the Pro Series lineup in a bolt-on format.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe comparison to COR-4807013 is the key buyer decision. COR-4807013 delivers 3-link front geometry and maximum front articulation at the cost of fabrication, custom exhaust, and CV driveshaft requirements. COR-4807002 delivers meaningful long arm front geometry improvement — better ride quality, more articulation than short arm — without any of those requirements. For a trail-capable LJ that still needs to function as a daily driver, COR-4807002 is the front half of that build. COR-4807003 is the rear half.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe upgrade path to 3-link is available later through COR-4807015 — not COR-4807013 — without duplicating hardware already installed by this kit.
