Description

Complete bolt-in mid-arm system for superior articulation. Features lower control arms from 2" x 3" billet 7075 Aluminum (PB+J series) and four other control arms from round 7075 Aluminum with X-Factor benefits. Offers 95 degrees of misalignment with Pro-X Krawler Joints and Adventure Series joints to reduce bind. Adjustable for precision caster and pinion angle. Includes Gen 2 front sway bar disconnects and TRIPLE-RATE coils for a comfortable on-road ride (better than OEM) and off-road articulation, staying seated in coil bucket with proper length shocks. Includes correction pads to reduce spring bow. Front and rear track bar geometry corrections for centered axles and optimal on-road handling. Provides excellent highway ride, superior off-road ability for a mid-arm system, improved rear roll center, and is upgradable to an RK Longarm System. Ensures the Jeep remains level. Lifetime warranty.
