Traxxas Primary Shaft 1st Speed Hub One-Way Bearing Snap Ring RC Drivetrain Part - 5593

The Traxxas TRX5593 is a drivetrain spare parts assembly for Traxxas transmission systems, supplying the key internal components needed to rebuild or repair the primary shaft assembly. The set covers the primary shaft, first speed hub, one-way bearing, snap ring, and a 5x8x0.5 thrust washer — the components that sit at the heart of the transmission and directly affect how power is transferred from the motor through the drivetrain. If your one-way bearing has failed, your first speed hub is worn, or your primary shaft is damaged, this assembly gives you everything required to carry out a complete rebuild of that section of the gearbox in a single purchase.
