TRAXXAS TRX-4 aluminum chassis crossmember by JAZRIDER JR-TRX401-BK  [JR-TRX401-BK]

Chassis crossmember for TRX-4

This aluminum crossmember is an RC-scale replacement part intended for TRAXXAS TRX-4 scale and trail crawlers. It provides a metal alternative to non-metal options to address flex and durability in demanding trail use.

Installation generally uses the vehicle's existing mounting points. Remove the original crossmember, position the aluminum part to align with frame holes, and secure carefully with the appropriate hex driver while checking fit and clearance with suspension components and the body.

In tuning terms this part is used to alter chassis stiffness and load paths; swapping to an aluminum crossmember can change how the chassis reacts over obstacles and during cornering, so re-check suspension geometry and weight distribution after fitment.
