Adjustable upper and lower arms with Pro Krawler joints at the axle and Adventure Series joints at the frame add up to 95 degrees of total misalignment, which is a lot of freedom for a bolt-in 4.5 inch kit. It is built for Sport and Overland Gladiators and it brings a complete bolt-in system, not just arms.\u003c\/p\u003e\u003ch3\u003eWhat's in the kit\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4 coil springs (triple-rate front, quad-rate rear)\u003c\/li\u003e\n\u003cli\u003e2 front adjustable high clearance lower control arms\u003c\/li\u003e\n\u003cli\u003e2 front adjustable upper control arms\u003c\/li\u003e\n\u003cli\u003e2 front spring pads\u003c\/li\u003e\n\u003cli\u003e1 adjustable front track bar\u003c\/li\u003e\n\u003cli\u003e2 Gen-II sway bar links\u003c\/li\u003e\n\u003cli\u003e2 rear adjustable high clearance lower control arms\u003c\/li\u003e\n\u003cli\u003e2 rear adjustable upper control arms\u003c\/li\u003e\n\u003cli\u003e2 rear spring pads\u003c\/li\u003e\n\u003cli\u003e2 adjustable rear sway bar links\u003c\/li\u003e\n\u003cli\u003e1 bolt-on rear track bar relocation bracket\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eShocks depend on the package you pick.
