Rear Frame Reinforcement

The TRX4015RN is an aftermarket 7075 aluminium crossmember made for TRAXXAS TRX4 and TRX6 scale trail crawlers. Machined from a high-strength aluminium alloy, the part gives a firmer rear mounting location to cut down chassis flex on steep or uneven lines.

Fitment callouts are listed below and the supplied fasteners allow installation on standard TRX4/TRX6 mounting points. The crossmember works with existing frame rails and suspension links to improve rear-end stability during slow, technical crawling sections.

Installation is straightforward with basic workshop tools; verify hole alignment and reuse or replace spacers where needed. Practically, the added stiffness helps preserve chassis geometry under load and can make handling more predictable when adjusting tyre compounds or shock tuning.

Packing includes

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

If you want a compact, tough rear crossmember for TRX4/TRX6 crawlers, this 7075 aluminium unit adds rear stiffness and includes the correct screws for fitment.

How do I confirm this will fit my TRX4/TRX6?

Check the Compatible Models list above against your vehicle's kit number to ensure the TRX4015RN matches your TRX4 or TRX6 variant.

Are the mounting fasteners included?

Yes, the kit ships with the Grade 12.9 screws shown in the Packing includes section for straightforward installation.

Will this change my suspension geometry?

The crossmember helps keep chassis geometry more consistent under load, which can slightly alter weight transfer and steering feel when you change tyres or adjust shocks.

Do I need to machine or modify chassis parts to fit?

No machining should be needed for listed compatible models; use standard hand tools and verify spacer placement during assembly.
