This is the stock-height set for the 2011-2019 GM HD: two 980-24-963 fronts for 0 to 1 in of front lift and two 980-24-664 rears for 0 to 1 in of rear lift. Each is a 2 in aluminum-body monotube with an internal floating piston separating the oil from the nitrogen, so the damping stays consistent when hot and there is no foaming on long washboard or with a trailer working the rear leaf springs. Firmer and more planted than the factory shocks on a torsion-bar HD, with FOX's race-derived high-flow piston and application-specific valving.\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\u003e2 front shocks + 2 rear shocks (one complete truck)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront\u003c\/th\u003e\n\u003ctd\u003eFox 2.0 Performance IFP 980-24-963, for 0 to 1 in front lift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRear\u003c\/th\u003e\n\u003ctd\u003eFox 2.0 Performance IFP 980-24-664, for 0 to 1 in rear lift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDesign\u003c\/th\u003e\n\u003ctd\u003e2.0 in impact-extruded 6061-T6 aluminum body, internal floating piston, 5\/8 in hard chrome shaft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrivetrain\u003c\/th\u003e\n\u003ctd\u003e2WD and 4WD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eFOX limited lifetime warranty (Performance Series purchased after 3\/30\/2025)\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\u003e2 x Fox 2.0 Performance Series IFP front shock, part number 980-24-963\u003c\/li\u003e\n\u003cli\u003e2 x Fox 2.0 Performance Series IFP rear shock, part number 980-24-664\u003c\/li\u003e\n\u003cli\u003eBushings, washers and hardware.
