TRAXXAS TRX4 Heavy Duty Lower Gear Mount TRX4038B by GPM  [TRX4038B]

Lower gear mount for trail use

This aluminium lower gear box mount is offered as a scale replacement and upgrade for the TRAXXAS TRX4 Trail Crawler to protect the central transmission zone and add structure to adjacent components. The part works as a lower chassis brace to limit gearbox movement under load and shore up chassis behaviour while crawling.

Its role is mainly protective and stabilising: a solid lower attachment reduces flex near the centre transmission, helps maintain suspension link geometry and improves handling predictability during tuning and heavy use. The alloy construction and secure fastenings are the key factors for lasting fit and performance.

Install this lower mount where a firmer gearbox support is required for TRX4 Trail Crawler builds; it acts as a straightforward reinforcement to protect the centre transmission during technical crawling.
