Built for Wrangler Unlimited owners who demand maximum articulation without sacrificing highway comfort, this 4-inch long-arm lift kit uses a true 4-link design to deliver extreme axle flex while keeping suspension geometry dialed. Run 33"–35" tires and conquer rock crawls and daily drives with the same setup.

What's included

  • Forged front track bar — solid-steel construction that keeps caster angles true and prevents bump-steer across obstacles.
  • N3 shock pair (front and rear) — nitrogen-charged absorbers tuned for smooth, controlled ride quality on pavement and trails.
  • Dual-rate coil springs (front and rear) — engineered to correct rear spring angle by 10 degrees and maintain optimal ride height under load.
  • Long-arm universal kit boxes (front, rear, and main) — complete brackets, fasteners, and extended stainless brake lines ready to bolt on.
  • X-Flex control arms — heavy-wall DOM tubing with OEM-style rubber bushings, fully rebuildable flex joints, and greasable 2.5" diameter bodies for unbeatable durability and travel.

Important notes

  • Does not fit 2-door Wrangler JK models — Unlimited (4-door) only.
  • Does not fit 2012–2018 model years.
  • An upgraded front and rear driveshaft is highly recommended to prevent binding and ensure safe power delivery at full articulation.

Why customers pick this at Road Runner

  • True 4-link geometry — adjustable front and rear upper and lower control arms eliminate rear-steer and binding under compression.
  • Corrected suspension angles — rear coil correction plates and dialed pinion alignment keep your rig stable at full droop and stuff.
  • Installed by techs who do this every week — we dial in geometry, perform alignment in-house, and test-drive every lift before you drive off.
  • Rough Country lifetime warranty backed locally — if anything fails, we handle the claim and swap parts on the spot.
  • Bolt-on setup — no welding, no crossmember removal, and stainless brake lines ship with the kit so install stays straightforward.
