  • 2007-2017 Jeep Wrangler Unlimited JK


Do you JK owners want to run flat fenders and get the absolute most out of their low COG build? This Rock Krawler 1.5" X Factor System was designed for just that. The 1.5" triple rate coils provide an unbelievable ride and tons of suspension travel. The high clearance adjustable lower control arms are more robust than stock arms ever thought of and are less likely to get you hung up on the trails. The adjustable front and rear uppers combine with the lowers to allow for almost unlimited suspension travel and adjustability beyond belief. The sway bar disconnects allow you to open up the off-road ability of your JK when disconnected. The front and rear stainless steel brake lines firm up the brake peddle to help control larger wheels and tires. The rear axle is pushed back 1" so it is properly centered under most standard Flat Fenders. Enjoy the street and the trails with the Rock Krawler 1.5" X Factor System with your low COG build.
