The lower control arms are Rock Krawler's PB+J (Pure Beef and Jealousy) mid arms, machined from 2 inch by 3 inch billet 7075 aluminum, and the other control arms are machined from round 7075 aluminum with X-Factor built in. This 4.5 inch bolt-in system is aimed at Sport, Overland and Mojave Gladiators and Rock Krawler bills it as having the best articulation of any mid-arm kit on the market.\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 billet 7075 aluminum adjustable lower control arms\u003c\/li\u003e\n\u003cli\u003e2 front 7075 aluminum adjustable upper control arms\u003c\/li\u003e\n\u003cli\u003e2 front spring pads\u003c\/li\u003e\n\u003cli\u003e1 front adjustable track bar\u003c\/li\u003e\n\u003cli\u003e2 Gen-II sway bar links\u003c\/li\u003e\n\u003cli\u003e2 rear billet 7075 aluminum adjustable lower control arms\u003c\/li\u003e\n\u003cli\u003e2 rear 7075 aluminum 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\u003cli\u003e1 carrier bearing bracket\u003c\/li\u003e\n\u003cli\u003e1 rear brake line kit\u003c\/li\u003e\n\u003cli\u003e1 rear adjustable track bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eShocks depend on the package you pick.
