Aluminium crossmember engineered for TRX-4

The JR-TRX401-GU aluminium crossmember is designed specifically for TRX-4 platforms and carries a gun metal finish to match scale styling. It replaces the centre stock member to reduce chassis flex while keeping the vehicle's appearance intact.

Materials and finish are chosen to balance trail durability with a compatible mounting footprint and modest mass. The part is intended as a tuning option to modify how the chassis distributes loads to the suspension and tyres.

Fitment is straightforward: the crossmember uses the TRX-4 stock mounting holes and standard fasteners, so ordinary hand tools are adequate. Apply balanced torque to fixings to prevent uneven chassis preload.

Tuning effect: a firmer centre crossmember will limit unwanted movement, often improving turn-in and providing firmer feedback for suspension setup. After installation, make measured adjustments to shock settings and springs to re-establish desired articulation and traction.

The anodized gun metal surface resists normal trail wear, but sharp impacts can mark it. Inspect after heavy use and clean debris to preserve finish life.
Yes. Increasing centre stiffness changes how the chassis twists under load, which affects articulation and may require small tuning changes to shocks and springs for best performance.
No special tools are required; standard hand tools and a sensible torque approach are sufficient for secure fitment.
