GPM TRAXXAS TRX4 Trail Crossmember Upgrade TRX4015R - RC Spare Part  [TRX4015R]

Aluminum crossmembers for TRAXX4 stability

This aluminium crossmember kit is made for TRAXXAS TRX4 trail crawler chassis as an aftermarket reinforcement. The set supports chassis links and gives a firmer mounting platform for damper assemblies to help preserve suspension geometry during demanding crawling sections.

Parts are machined for accurate fit and finished with a slim 3D profile to reduce bulk while keeping clearance around the drivetrain and suspension. The kit includes the small stainless steel fasteners listed in the original packing information for direct replacement of compatible factory screws.

Installation notes: the crossmembers bolt to existing chassis points and interface with link mounts and damper towers; use the supplied screws to secure the parts to factory mounting locations and check alignment before final torque. From a tuning perspective, adding these crossmembers increases stiffness at mount points, reducing unwanted movement and making damper response more repeatable on technical lines.

This crossmember set provides a simple way to reinforce TRX4 link and damper mounting points without changing core suspension geometry, useful for builders who want steadier on-trail performance.
