A full rebuild of a GM 12-bolt truck rear end (8.875 in. ring gear) calls for replacing the bearings and seals together rather than one worn part at a time. This Hurst Engineering master overhaul kit gathers the bearings and seals needed for a complete axle overhaul on 1963-1991 Chevy and GMC C/K and R/V trucks, which makes it the natural companion to a gear change, a carrier upgrade or new axle shafts.
