The X-Factor Pro package is the lightweight route: all eight arms are machined from 7075 aluminum, and Rock Krawler uses its proven Adventure Series joint in six locations with Pro-X Krawler joints in the rest. The company says that yields half the maintenance of other aluminum arm packages and up to 95 degrees of total misalignment out of the lowers.
Every arm adjusts in the vehicle, with wrench flats machined into the center of each arm so the jam nuts are easy to tighten.
