This 2-piece adjustable main drive shaft set is made for the GMADE R1 Rock Buggy, combining 6061-T6 aluminium shaft bodies with steel hardware to deliver a practical strength-to-weight balance for scale drivetrain use.
Aluminium shaft bodies cut down on rotating mass compared to solid steel shafts, which can ease battery load on electric rigs while keeping driveline geometry true. Retaining screws are secured with steel wire rings to help avoid fastener loss on rough terrain.
Length adjustment is integrated: front shaft 122mm to 132mm and rear shaft 105mm to 115mm. O-rings and mounting screws are included so you can fit the shafts straight away without hunting for extras.
For reliable performance install with correct torque on the M4 screws, ensure the wire ring is seated, and check for smooth rotation and correct alignment after fitting to prevent binding at transmission outputs.
A simple drivetrain upgrade for R1 owners seeking adjustable lengths and reduced rotating inertia; keep fasteners checked after trail sessions.
