Now available from HPI Racing are new wheels for 2WD and 4WD trucks in several colors and finishes! These wheels bolt right onto our popular Nitro Rush and Nitro MT kits, and will also fit most of the popular trucks on the market. Front wheels use 3/16 x 3/8 x 1/8 inch unflanged bearings. The rear wheels include adapters and washers to fit non-HPI trucks. 4WD truck owners will use the rear wheels for the front and rear.
