The GPM SLAM4041 package supplies 4140 carbon steel front and rear driveshafts and matching drive cups intended to increase drivetrain durability on TRAXXAS MINI SLASH 4X4 models running high-power brushless setups. Heat treated black surface hardening improves wear resistance and maintains efficient torque transfer, while the CVD joint form allows greater steering articulation without binding. These components focus on reliable load handling and predictable drivetrain behaviour during sustained high torque operation.
