About this part

6-Inch Component Box, fitment-checked

One of the boxes making up Skyjacker's 6 in. GM heavy duty lift — the A section. A kit this size ships in more than one carton, so check which boxes the parts list calls for. Three exclusions apply across this family: not for 17 in. or 18 in. OEM wheels, not for Magnetic Ride Control models, and gas trucks may need the OEM exhaust modified for driveshaft clearance.

A 6 in. heavy-duty lift is too large to arrive in one carton, and Skyjacker splits it into lettered and suffixed component boxes. This is the A box. Ordering it alone will not lift a truck; read the parent kit's parts list and confirm every box is on the order. Coverage is the 2020-2025 Silverado 2500 HD and 3500 HD and the GMC Sierra equivalents in 4WD. Three exclusions apply across this family: not for 17 in. or 18 in. OEM wheels, not for Magnetic Ride Control models, and gas trucks may need the OEM exhaust modified for driveshaft clearance.
