TRAXXAS TRX-4 Aluminum Chassis Crossmember - JR-TRX401-GU by Jazrider  [JR-TRX401-GU]

Stiffer centre crossmember for TRX-4

This JR-TRX401-GU RC-scale aluminum chassis crossmember is made for TRX-4 platforms and finished in gun metal. It replaces the factory centre crossmember to provide a stiffer link between the rails while maintaining a scale appearance.

Material choice and finish are selected for durability and a visual match with common scale builds, while keeping weight and the mounting footprint compatible with stock attachment points. The part balances strength and low added mass for trail use.

Installation notes: this crossmember uses the stock TRX-4 chassis mounting pattern and standard fasteners, so basic hand tools are sufficient. Apply even torque when fastening to avoid introducing chassis preload.

Tuning role: fitting a stiffer centre crossmember reduces unwanted chassis flex, which can sharpen turn-in and give more consistent feedback for suspension adjustments. Expect changes in articulation and plan small, incremental shock or spring changes to rebalance travel and traction.
