Designed with a focus on material strength and reduced mass, the GPM rear CVD drive shaft is a direct replacement for the Traxxas Ford Fiesta ST Rally rear driveline. The constant velocity configuration aids consistent torque transmission while carbon steel main elements combined with 6061-T6 aluminum components deliver a balance of toughness and low weight appropriate for competitive club running or frequent use. Installation follows standard rear shaft procedures and uses the supplied screw pins for secure fitting.
