The GPM 32-tooth heavy-duty differential gear is produced from 20CrMnTi steel, hardened and blackened to optimise surface wear resistance for demanding use on the TRAXXAS FUNCO PRO SCALE 2WD SAND CAR. Its M1.5 tooth profile and 32-tooth count are specified to match factory geometry so the component installs as a direct replacement for original part 10979. Use this part where enhanced gear longevity is required without altering drivetrain geometry.
