Precision Rear Chassis Crossmember

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.

Packing includes

  • chassis crossmember - 1pcs
  • Grade 12.9 black Round Head Screws 3x12 - 4pcs
  • Grade 12.9 black Round Head Screws 3x10 - 2pcs

This precision 7075 aluminium crossmember is intended for builders seeking a durable, low-profile reinforcement to reduce rear chassis deflection on TRX4/TRX6 scale crawlers.

Tighter machining tolerances reduce play at mounting points, which helps preserve link geometry under load and improves consistency in steering and weight transfer.
7075 offers higher yield and tensile strength compared with common 6xxx-series alloys, providing improved resistance to bending and fatigue in stressed chassis components.
The kit includes Grade 12.9 screws which are specified for high strength applications and suit the direct mounting points listed for compatible models.
Install loosely first, confirm spacer positions and link lengths, then torque fasteners progressively while checking roll centre and ride height to maintain intended geometry.
