The GPM TXMM5051 upgrade provides 4140 carbon steel front and rear driveshafts plus drive cups for the TRAXXAS MINI MAXX MONSTER TRUCK, aimed at enhancing component longevity and drivetrain behaviour. These shafts smooth the transmission of motor torque into the drivetrain, which helps preserve steering consistency. The CVD configuration increases steering angle capacity, and the black hardening treatment raises surface wear resistance compared with original equipment.
