This aluminium cross brace serves as a scale replacement for TRAXXAS TRX-4 trail and scale crawlers, providing a stiffer metal alternative to stock parts for improved longevity under heavy trail use.
Installation uses the existing frame mounts: remove the original crossmember, place the aluminium unit to align with the chassis holes, and tighten carefully while ensuring there is no interference with suspension or drivetrain parts.
In tuning terms, swapping to an aluminium cross brace will change chassis stiffness and how loads pass through the frame; expect differences in obstacle response and corner behaviour and check suspension geometry after fitment.
