This aftermarket four-piece aluminium spur gear case is a direct-fit replacement for the TRAXXAS TRX4 Trail Crawler plastic housing, aimed at boosting strength and steering consistency. CNC-quality 6061 T6 aluminium and a straight arm profile limit flex while keeping correct gear mesh during slow, technical crawling and trail driving.
The component is focused on improving chassis tuning and mechanical stability rather than changing final drive ratios. With its dual tie rod holes you can switch attachment points to refine steering throw and toe without fabricating new linkages. Intended for aftermarket use on the TRX4 platform only.
