About this kit

It does not fit TRD Pro models or trucks with the KDSS or X-REAS system, and 2015 vehicles need a production date of 5/2015 or later.
This 6-inch lift kit for the 2015-2020 Toyota 4Runner covers SR5, SR5 Premium, Limited, Nightshade, Trail, Venture, and TRD Off-Road applications listed in the fitment section, in both 4WD and RWD. Contents include the knuckle, crossmember, and skid plate boxes, a 4.5in box strut kit, rear track bar, coil, an M1 monotube shock pair, and an M1 loaded strut pair. No strut disassembly or spring compressor is needed, so the front assemblies go in as delivered.
