TRAXXAS TRX4 Aluminium Crossmember Kit TRX4015R by GPM  [TRX4015R]

Heavy-duty aluminium crossmember kit for TRX4

This aluminium crossmember assembly is an aftermarket reinforcement intended for TRAXXAS TRX4 trail crawler frames. It supplies structural support for the chassis links and a more rigid mount for damper units to help maintain suspension geometry on tight or steep lines.

Each part is CNC-styled for consistent fitment and finished with a slim three-dimensional profile to reduce additional bulk while keeping clearance near drivetrain and linkages. The set includes the small stainless steel fasteners referenced in the original packing information so you can swap directly with compatible factory screws.

Fitment notes: these crossmembers fasten to existing chassis mounting points and mate with link mounts and shock towers; use the included screws and verify alignment before final tightening. In setup terms, the extra bracing raises stiffness at the mounts which can cut down chassis flex and make damper performance more predictable on rough sections.

A straightforward reinforcement for TRX4 builders chasing steadier link behaviour and repeatable shock mounting under trail load.
