Rear Chassis Brace

The TRX4015RN rear chassis crossmember is an aftermarket 7075 aluminium replacement for TRAXXAS TRX4 and TRX6 scale trail crawlers. CNC-style machining of 7075 aluminium gives the part the strength to reduce rear section deflection during extreme articulation.

Compatibility is listed in the model box below and the supplied screws allow mounting to standard TRX4/TRX6 points. As a reinforcement, the crossmember ties into existing frame rails and suspension links to steady the rear end during slow technical crawling.

Fitting requires basic hand tools and careful alignment with the factory holes; keep or swap spacers as necessary. In practical tuning terms this component helps stabilise chassis geometry under load, aiding predictable steering and balance when trying different tyres or shock setups.

Packing includes

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

This low-profile 7075 aluminium rear crossmember is ideal for TRX4/TRX6 scale crawling builds that need extra rear stiffness and it arrives with the screws required for mounting.

Do I need to trim or modify the chassis to fit this part?

For the models listed in the compatibility box, no trimming should be necessary; the crossmember fits the stock mounting geometry using the included screws.

What benefits will I notice on the trail?

Expect improved rear-end support and reduced deflection under articulation, which helps the chassis behave more consistently when negotiating obstacles.

Is specialised hardware required for fitting?

No special hardware is needed beyond common hex drivers; the kit includes the listed Grade 12.9 screws for mounting.

Can this part affect axle geometry or link angles?

It helps maintain chassis geometry under load, which can change how weight shifts and slightly influence link angles; check geometry after installation and during tuning.
