About this kit
Long Arm Upgrade Kit, fitment-checked
A bolt-on 4-link long arm conversion for the 2007–2017 Jeep Wrangler, aimed at JKs already running 4-6 inches of lift. Front and rear adjustable arms ride on rebuildable flex joints in a 2.5in body with 1.25in threads, and coil correction plates reset the rear spring angle by 10 degrees. Braided stainless brake lines, quick disconnects, a track bar drop bracket and extended sway-bar links are part of the kit. Upgraded driveshafts front and rear are strongly recommended.
The kit is a true 4-link setup for the 2007–2017 Wrangler and Wrangler Unlimited, Sport through Rubicon, and it only belongs under a Jeep carrying 4-6 inches of lift. Longer arms on rebuildable flex joints buy articulation without the bind and rear-steer that short-arm geometry fights at that height. The front side brings upper and lower adjustable arms, frame strengthening brackets, an exhaust spacer, sway-bar quick disconnects and braided brake lines; the rear adds coil correction plates and a track bar drop bracket. No welding needed. Budget 8-10 hours and plan the driveshaft upgrades alongside it.
