Engineered for serious off-roaders, Rough Country's 4-Inch Long-Arm Lift Kit for Jeep Wrangler Unlimited 4WD (2004–2006) expands axle articulation, boosts travel, and equips your TJ Unlimited with rugged, trail-ready hardware.

• All-Inclusive 4-Inch Long-Arm System: High-travel front and rear arms with a high-clearance design that minimizes binding and rear-steer while maximizing axle articulation for aggressive terrain.
• Forged Adjustable Track Bars: Front and rear forged steel track bars (16 lb each) provide robust strength, on-vehicle adjustability, and precise axle alignment as you flex.
• X-Flex Joints: Advanced joint design that enhances articulation and reduces binding, helping maintain steering control during extreme flex and rock traversal.
• Long Travel, High-Clearance Arms: Built to clear obstacles with improved approach/departure angles, while keeping pinion angles optimized through the full range of motion.
• Sway Bar Disconnects: Quick-release capability to maximize wheel travel off-road and re-connect for stable highway handling.
• Premium N3 Shocks: Tuned damping for smoother, more controlled rides across rough terrain, helping absorb impacts from rocks and ruts.
• OEM-Style Rubber Bushings: Durable, maintenance-friendly bushings that balance performance with long-term reliability.
• Lifetime Replacement Warranty: Rough Country’s commitment to quality means you’re covered for the lifetime of the product.

This kit is built for those who push their Jeeps beyond stock capability — ideal for serious crawlers, overlanders, and trail enthusiasts who demand maximum flex, consistent pinion angles, and dependable durability on rock faces, granite slabs, and rough desert trails. The forged track bars and X-Flex joints work together to reduce axle wrap and prevent binding, so you’ll experience steadier steering and improved traction when you need it most. With on-vehicle adjustability and a complete set of rugged components, you can dial in stance and alignment to suit your preferred ride height and trail conditions, then lock it in for long-term reliability. The result is a more capable, more confident Jeep that handles obstacles on your terms.
