The Rock Krawler Suspension 4.5" X-Factor PRO ELITE Mid-Arm System is a complete, bolt-in suspension lift kit for Jeep Wrangler JKU (4-door) models, designed for excellent articulation. It features PB+J (Pure Beef and Jealousy) mid-arms machined from 2" x 3" billet 7075 Aluminum for lower control arms and round 7075 Aluminum for other control arms, all with X-Factor built-in. Pro-X Krawler Joints and Adventure Series joints offer 95 degrees of misalignment, reducing bind. The system allows precision tuning of caster and pinion angle. It includes TRIPLE-RATE coils for comfortable on-road ride, proper off-road articulation, and controlled reaction to terrains, with correction pads to reduce spring bow. Front and rear track bar geometry corrections ensure centered axles and uncompromised on-road handling.
