TRAXXAS TRX4/TRX6 Rear Chassis Brace TRX4015RN by GPM  [TRX4015RN]

Rear Chassis Support

The TRX4015RN is an aftermarket 7075 aluminium rear chassis crossmember suitable for TRAXXAS TRX4 and TRX6 scale trail crawlers. Manufactured from 7075 aluminium, the part provides a stronger mounting point at the rear to limit flex under heavy articulation.

The compatibility list below shows applicable chassis and kits, and the package contains the mounting screws required for use with standard TRX4/TRX6 points. The crossmember acts as a reinforcement that complements existing frame rails and suspension links to steady the rear end during technical crawling.

Installation calls for basic hand tools and careful alignment with the stock holes; keep or replace spacers to maintain correct link geometry. In tuning terms this upgrade helps retain chassis geometry under load and can make vehicle reactions more predictable when changing tyres or shock settings.

For a durable, discreet rear crossmember on TRX4/TRX6 crawling builds, this 7075 aluminium replacement increases stiffness and includes the correct mounting hardware.
