The Rock Krawler coilover for the X Factor Pro Aluminum system is specified for the 4.5in Pro package on 2019–present Jeep Wrangler (JT) models. As a matched coilover within the Pro Aluminum kit, it combines spring and damper components tailored to Rock Krawler’s 4.5in Pro specification to preserve ride height and suspension behavior intended by the aluminum-based upgrade.
