TRAXXAS TRX4 Trail Crossmember Upgrade TRX4015R by GPM  [TRX4015R]

Precision aluminium crossmembers for TRX4 reinforcement

This aluminium crossmember assembly is an aftermarket reinforcement for TRAXXAS TRX4 trail crawler frames, engineered to provide improved rigidity at link and damper mounting locations. The set is intended for hobbyists seeking a CNC-styled chassis brace that reduces localized flex and promotes repeatable damper performance under load.

Components are machined with attention to fit and a slim profile to retain clearance around driveline and suspension hardware. Fasteners shown in the original packing information are included to allow direct substitution where compatible with factory screw points.

Technical notes: crossmembers bolt to designated chassis points and mate with existing link mounts and damper towers; final assembly requires correct alignment and torque checks. From a setup perspective, the increased stiffness at key mounting interfaces reduces unwanted movement and helps maintain predictable shock response on steep or technical sections.

Engineered for consistent fit and improved mount durability, this crossmember set is a practical upgrade for TRX4 builds focused on reliable on-trail performance.
