Associated ASC91552 Gearbox 4 Gear V2 (Right & Left)

This is the genuine Associated 91552 4-gear gearbox, version 2, sold as a matched right and left pair. This gearbox houses the internal gearing that transfers power from your motor through the transmission and out to the driveline, making it one of the most critical components in your drivetrain.

A worn or damaged gearbox case can lead to poor gear mesh, increased drivetrain noise, and premature wear on the gears themselves, so replacing a cracked or stripped housing restores smooth, reliable power transfer. This version 2 design reflects Associated's updated gearbox architecture, giving you the current factory-spec housing rather than an outdated original.

Since this listing includes both the right and left gearbox halves, you get a complete, matched set ready to house your internal gearing without needing to source each side separately. This is a direct-fit replacement built to Associated's factory tolerances.
