TRAXXAS E-MAXX Steel and Aluminum Front/Rear Main Shafts 14pcs by GPM EMX2037S  [EMX2037S]

Front and rear main shafts for E-MAXX

This 14pcs shaft set is an RC-scale drivetrain replacement designed for TRAXXAS E-MAXX platforms. The design pairs an aluminum 6061 T6 shaft body with steel #45 CVD heads to balance reduced rotating mass and local strength at the drive interface. Reduced shaft weight helps lower drivetrain inertia, which can slightly improve battery run time and reduce stress on the transmission during acceleration and deceleration.

Practical notes for fit and use: lengths are 85mm for the front shafts and 132mm for the rear shafts, matching common E-MAXX layouts. The steel CVD ends are intended for wear resistance where the drives couple to dogbones or drive cups, while the aluminum shaft body reduces overall weight. The set also includes small hardware typically used when replacing shafts.

Use this set when you want to replace worn stock shafts or tune the balance between strength and rotating weight on an E‑MAXX. Check spline fits and clearance during installation and verify that CVD ends engage securely with existing drive cups.
