XRAY 354021 - GTX Aluminium Center 2-speed Upper Mount (Brake, Flat Chassis)  [XR-354021]

Aluminium 2-speed upper mount

This XRAY 354021 aluminium upper mount is a CNC-machined center component designed for flat-chassis GTX applications. It combines the 2-speed transmission upper support with an integrated brake caliper mounting point to keep shifting and braking geometry consistent under race loads.

The part's Swiss 7075 T6 aluminium construction increases stiffness in the drivetrain tower area, reducing flex that can disturb 2-speed engagement or brake alignment. Precision machining ensures repeatable fitment to the chassis mating points and predictable interaction with the gearbox and brake assembly.

From a setup perspective the component acts as a fixed reference between the gearbox and the brake system. Tuners use it to stabilise shift timing and maintain consistent pad alignment without adding additional stack-ups to the chassis layout. It is intended solely for RC-scale GTX platforms configured with a flat chassis layout.

Choose this mount when you need a rigid, precisely machined centre tower that preserves brake alignment and supports reliable 2-speed shifting on GTX flat-chassis RC cars.
