The X-Factor mid-arm package replaces all eight JK control arms in a single order. Every lower is formed for high clearance with an Adventure Series joint at the frame and a Pro-X Krawler joint at the axle, good for up to 95 degrees of total misalignment according to Rock Krawler.
The front uppers adjust in the vehicle for caster. The rear uppers pair an Adventure Series joint at the frame with a Pro-X joint at the axle, also adjustable in the vehicle, so pinion angle is easy to set.
