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. Race-derived high-flow piston, application-specific valving. FOX specifies aftermarket upper control arms with this front on the 2020+ truck, see the question below.\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 985-24-240, for 1.5 to 2.5 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 985-24-239, 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\u003eRequires\u003c\/th\u003e\n\u003ctd\u003eAftermarket upper control arms (FOX requirement for the 985-24-240 front)\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 985-24-240\u003c\/li\u003e\n\u003cli\u003e2 x Fox 2.0 Performance Series IFP rear shock, part number 985-24-239\u003c\/li\u003e\n\u003cli\u003eBushings, washers and hardware.
