This 3.5 inch Drive Right system for the Jeep Wrangler JKU 4-Door is built around getting the geometry right once the Jeep is up in the air. An adjustable front track bar and a raised rear track bar bracket recenter both axles, and high-clearance adjustable front lower control arms let you set caster and cross-caster without shortening the wheelbase. It is the entry point to Rock Krawler's mid-arm line, and Rock Krawler says it can be upgraded to the Adventure-X Mid-Arm system later without starting over.\u003c\/p\u003e\u003cp\u003eRock Krawler bases its lift heights on Rubicon models in a standard build, meaning a front bumper and winch, a rear bumper and a full-size spare.\u003c\/p\u003e\u003ch3\u003eWhat's in the kit\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4 x triple-rate coil springs\u003c\/li\u003e\n\u003cli\u003e2 x front adjustable lower control arms\u003c\/li\u003e\n\u003cli\u003e1 x adjustable front track bar\u003c\/li\u003e\n\u003cli\u003e2 x rear spring pads\u003c\/li\u003e\n\u003cli\u003e2 x adjustable rear sway bar links\u003c\/li\u003e\n\u003cli\u003e1 x bolt-on rear track bar relocation bracket\u003c\/li\u003e\n\u003cli\u003e4 x stainless steel brake line relocation brackets\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBump stops come with every shock package.
