Important Notes
Description
Rock Krawler's 2.5" Expedition System Lift Kit provides improved off-road performance with excellent highway ride and handling. The rear axle is pushed back up to 1" over stock which perfectly centers the rear axle assembly under typical aftermarket flat fenders. It also allows for larger tires without contacting the rock sliders or rear pinch seam. This complete bolt in system is upgradeable to any other Rock Krawler system.
