TRAXXAS TRX4 Aluminium Chassis Crossmember Set TRX4015R by GPM  [TRX4015R]

Aluminium crossmember upgrade for TRX4 chassis

This aluminium crossmember kit is an aftermarket reinforcement for TRAXXAS TRX4 trail crawlers. It acts as structural support for the chassis link system and provides a firmer, more consistent mounting area for damper fittings to help retain geometry during technical crawling.

The components are machined for repeatable fit and finished with a slim three-dimensional profile to minimise interference with driveline and suspension parts. The kit includes the small stainless steel fasteners referenced in the original packing information so compatible factory screws can be replaced directly where needed.

Fitting notes: crossmembers attach to existing chassis locations and interface with link mounts and shock towers; secure parts with the supplied screws and check alignment before final tightening. From a setup viewpoint, these crossmembers increase stiffness at key mount points, reducing unwanted movement and yielding steadier damper behaviour under load.

A handy aftermarket reinforcement for TRX4 builders wanting improved consistency at link and damper mounts without altering core suspension geometry.
