TRAXXAS TRX4 Lower Chassis Gearbox Mount TRX4038B by GPM  [TRX4038B]

Under-chassis gearbox brace for TRX4

This aluminium lower gear box mount is produced as a replacement hop-up for the TRAXXAS TRX4 Trail Crawler to protect the centre transmission and strengthen surrounding assemblies. It provides a lower structural brace that limits gearbox movement and helps the chassis resist twisting during crawling sections.

Functionally it serves to protect and stabilise: the rigid lower mounting point reduces flex around the central transmission, keeps suspension link geometry more stable and aids consistent handling when adjusting suspension or running technical lines. Solid construction and proper mounting are the main contributors to long term fit and durability.

Choose this mount to add a firmer lower gearbox support on TRX4 Trail Crawler setups; it is a simple reinforcement that complements suspension tuning and shields the centre transmission on demanding terrain.
