4" 1997-2006 Jeep Wrangler TJ 4WD Long Arm Lift Kit by Rough Country

The Rough Country 66330 4" Long Arm Lift Kit is a premium suspension system built for 1997–2006 Jeep Wrangler TJ 4WD owners who demand maximum articulation, superior trail performance, and dependable on-road handling. Designed to outperform traditional short-arm systems, this complete long arm kit delivers smoother suspension movement, improved axle control, and increased ground clearance for serious off-road use.

At the heart of this system are front and rear adjustable upper and lower long control arms engineered with high-clearance construction for better obstacle clearance. These heavy-duty arms feature OEM-style rubber bushings on one end and massive flex joints on the other, allowing superior suspension travel while reducing binding and harshness. The result is improved pinion angle control, reduced rear steer, and excellent ride quality on rough terrain.

Lifted high-flex coil springs provide the 4" lift height while maintaining a comfortable ride and increased suspension travel. Front control arm mounting brackets are included to properly position the long arms and optimize suspension geometry.

This system also includes forged adjustable front and rear track bars for precise axle centering and improved stability. A supplied pitman arm, front track bar drop bracket, and stainless steel braided brake lines complete the geometry and brake travel corrections needed after lifting.

Trail capability is enhanced with front sway bar quick disconnects and extended rear sway bar links, allowing greater articulation when the terrain gets rough. Premium N3 shock absorbers provide balanced ride comfort and dependable off-road damping control.

Backed by Rough Country’s Limited Lifetime Replacement Warranty, this lift kit is built to handle years of hard use.
