The GPM SERV237C main shaft is produced from high quality steel with attention to dimensional tolerances to support consistent drivetrain performance in the Traxxas 1:16 Mini E-REVO. Its construction is aimed at reducing component wear and preserving alignment under sustained load, which helps extend service intervals and maintain predictable handling. Designed for a direct fit, the shaft integrates with the Mini E-REVO drivetrain to simplify installation and setup refinements.
