The MJ237A centre shaft set upgrades AXIAL SMT10 drivetrains with an aluminium shaft tube and a hardened steel joint head to trim rotating weight while keeping the wear surfaces strong. It is aimed at hobbyists seeking a more responsive drivetrain without compromising durability.
Telescoping adjustment covers 138-148mm to suit typical SMT10 wheelbases, and the kit uses stainless steel screws plus O-rings for secure, corrosion-resistant assembly. The lighter shaft body reduces rotational inertia and can make throttle inputs feel sharper.
Fitting is simple for those used to SMT10 layouts: match and align splines, secure the joint using the supplied fasteners, and check O-ring seating to limit slack. Periodic inspection after several runs helps catch loose fasteners or worn O-rings early.
A sensible replacement for SMT10 builds where reduced rotating mass and solid joint strength are priorities, the MJ237A suits daily driving and tuning alike.
