This aluminium rear gear box set is a 16 pcs RC-scale replacement built for compatibility with TRAXXAS TRX4 Trail Crawler rear assemblies, listed as model TRX4013.

Installation notes: parts are supplied separately and are intended to replace specific stock components; test fit each item on your TRX4 Trail Crawler rear assembly before completing installation and keep original fasteners for reference.

This TRX4013 aluminium rear gear box set is supplied as a metal replacement pack for TRAXXAS TRX4 Trail Crawler rear assemblies, intended to steady mounting points and drivetrain alignment for scale crawling. Confirm part positions and screw lengths against your chassis prior to final tightening.
