TRAXXAS TRX4 Trail Crawler Aluminum Crossmember Set by GPM TRX4015R  [TRX4015R]

Aluminum crossmember set for TRX4

This is an RC-scale aluminum crossmember kit designed for TRAXXAS TRX4 trail crawler platforms and offered as an aftermarket part by GPM. The set functions as structural support for the chassis links and provides a stiffer, more consistent mounting point for damper assemblies, helping to maintain geometry during steep or technical crawling.

The components are machined for fit and finished with a slim, 3D-styled profile to reduce bulk while preserving clearance around drivetrain and suspension components. The kit includes the small stainless steel fasteners shown in the original packing information for direct replacement of the factory parts where applicable.

Installation notes: the crossmembers attach to existing chassis locations and interface with link mounts and damper towers; use the supplied screws to secure the parts to factory mounting points and check alignment before final tightening. In tuning terms, installing these crossmembers increases chassis stiffness at the mount points, which can reduce unwanted movement under load and make damper response more repeatable on trail sections.

This GPM crossmember set provides a straightforward way to reinforce TRX4 chassis link and damper mounting points without altering basic suspension geometry, making it useful for builders focused on consistent on-trail performance.
