This GPM centre shaft set is engineered to reduce rotating mass while maintaining strength for AXIAL SMT10 drivetrains. The design pairs a hardened steel joint with an aluminium shaft body to improve responsiveness, and stainless steel screws are used to resist corrosion during extended use. Adjustable from 138mm to 148mm, the shaft allows precise driveline geometry adjustments to match battery placement and suspension setup, supporting more consistent power delivery.
