The Bilstein 6112 kit for these trucks is built to the taller factory geometry: a 60mm monotube coilover with Bilstein's own cold-wound spring, adjustable from the factory lifted height up to another 1.2 in. The two 5160 rears carry the same digressive valving with a remote reservoir that keeps the oil cool on long dirt roads and heavy loads. Bilstein sells the fronts and rears as separate part numbers; this kit puts the correct Trail Boss \/ AT4 set in one order.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"hs-glance\"\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eKit contents\u003c\/th\u003e\n\u003ctd\u003eFront coilover kit (2 struts + 2 springs) + 2 rear reservoir shocks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront\u003c\/th\u003e\n\u003ctd\u003eBilstein 6112 47-309524, 60mm monotube, matched coil, 0 to 1.2 in lift over factory Trail Boss \/ AT4 height\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRear\u003c\/th\u003e\n\u003ctd\u003eBilstein 5160 25-316964, 46mm monotube, remote reservoir, 0 to 1 in rear lift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrivetrain\u003c\/th\u003e\n\u003ctd\u003e4WD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e6112: limited lifetime. 5160: 2 years (Bilstein North America)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\u003cdiv class=\"hs-specs\"\u003e\n\u003ch3\u003eWhat is in the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bilstein 6112 front kit 47-309524: two 60mm struts, two coil springs, two billet spring seats, snap rings, hardware\u003c\/li\u003e\n\u003cli\u003e2 x Bilstein 5160 rear reservoir shock 25-316964 with reservoir clamps and hardware\u003c\/li\u003e\n\u003cli\u003eInstructions for both.
