When Gray competed in 2010, his rig was equipped with a Dana 60 front axle, but not anymore. The latest variation of this GMC comes to the competition sporting a Rockwell 2 1/2-ton axle with 2-inch, Ouverson 47-spline ’shafts, 6.72:1 gears, Ouverson Violator joints and an Ouverson locker. Ruff Stuff Specialty’s brackets and 1 1/4-inch spherical rod ends were used in the reworking of the four-link suspension to accommodate the new axle, while a DIY4X Rockwell skid provides diff protection. Gray is still using the F-O-A coilovers and air bumps from 2010, but has upgraded the steering to a PSC 3-inch double-ended ram system to turn the big Mickeys.
