The TRX4015RN rear chassis crossmember is an engineered 7075 aluminium aftermarket replacement for TRAXXAS TRX4 and TRX6 scale trail crawlers. Machined for tight tolerances, the component provides a rigid rear mounting point to reduce flex under articulation and preserve link geometry during technical crawling.
Compatibility details are retained below and the kit includes the fasteners required for standard TRX4/TRX6 mounting locations. As a reinforcing element, the crossmember integrates with existing frame rails and suspension links to enhance rear-end control when slow-crawling over uneven surfaces.
Fitting requires common hand tools and accurate alignment with factory holes; verify spacer usage to maintain correct ride height. From a setup standpoint, the part helps hold chassis geometry under load, delivering more repeatable steering and weight transfer characteristics when experimenting with tyre and shock configurations.
