Long Arm Upgrade Kit | 4-6 Inch Lift | Jeep Wrangler Unlimited 4wd (04-06)

Built for Jeep Wrangler Unlimited owners who want serious ground clearance and trail articulation without compromise, this long-arm upgrade kit delivers a full 6 inches of lift while maintaining optimal suspension geometry. The X-Flex adjustable control arms—front and rear—preserve caster and allow extreme wheel travel, so your rig climbs harder and handles better than a simple coil spacer ever could.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• Upper adjustable control arms (front) — maximize articulation with pivot points rated to 20 degrees, keeping your suspension geometry square through extreme articulation.
• Lower adjustable control arms (front) — high-clearance design clears the engine bay and steering components, with flex joints rated to 35 degrees for extreme travel.
• Upper adjustable control arms (rear) — maintain proper pinion angle and axle centerline through the full lift range.
• Lower adjustable control arms (rear) — work with the track bar drop bracket to keep suspension geometry correct and prevent binding.
• Control arm mounting brackets — position the front arms on the frame for correct caster and camber.
• Track bar drop bracket — relocate the rear track bar connection to preserve axle centerline after the 6-inch lift.
• Rubicon compressor bracket — secures the air suspension compressor on Rubicon models during the lift.
• X-Flex control arm features — Clevite OEM-style rubber bushings, fully greasable 2.5" diameter flex joints with 1.25" thread for durability and easy maintenance.
• Hardware — all fasteners, bolts, and mounting hardware needed for complete assembly.

Important notes

• Fits Unlimited models only — not compatible with standard TJ Wranglers.
• A Slip Yoke Eliminator (SYE) with CV driveshaft is recommended to avoid driveline vibration. Rubicon models do not require a transfer case drop, but a CV driveshaft is still strongly recommended.
• Exhaust will need to be cut and rerouted to ensure clearance from moving suspension components.
