This aftermarket main shaft is supplied as one piece for use with TRAXXAS SLASH 4X4 drivetrains. It combines an aluminium shaft body with hardened steel end fittings to limit rotating mass while keeping the wear surfaces strong.
Fitting is straightforward for anyone used to Slash 4X4 service: remove the original shaft, inspect splines and bearings, then fit the replacement using the original retaining screws. No specialist tooling is normally required.
In practical tuning terms the low-CG design helps concentrate less mass at the outer ends and the steel fittings preserve spline life, which can result in smoother power transfer and reduced service frequency for off-road running and club events.
This shaft is intended as a direct replacement where reducing rotating mass and reinforcing bearing interfaces is desired; always confirm spline and retention compatibility before installation.
