AXIAL SMT10 Front & Rear Center Shaft 138–148mm by GPM MJ237A  [MJ237A]

Center shaft set for AXIAL SMT10

This GPM MJ237A center shaft set is a scale RC driveline upgrade designed for the AXIAL SMT10 platform. It combines an aluminum shaft body with a hardened steel joint head to reduce rotating mass while keeping the load-bearing joint durable.

The telescoping length is adjustable between 138mm and 148mm to match common SMT10 wheelbases, and the set uses stainless steel screws and O-rings for corrosion resistance and secure assembly. The lighter shaft body helps reduce drivetrain inertia, which can translate to slightly longer run times on the same battery and a more responsive drivetrain feel.

Installation is straightforward for hobbyists familiar with SMT10 driveline layouts: verify spline alignment, secure the steel joint to the output using the supplied fasteners, and confirm O-ring seating to limit play. Periodic inspection of the joint and fasteners is recommended after a few runs to retain reliable performance.

A practical replacement or hop-up for SMT10 builds where lower rotating mass and a robust joint are desired, the GPM MJ237A offers a balance of lightness and durability for everyday RC driving and tuning.
