XRAY 354022 - GTX Aluminium Center 2-speed Upper Mount (Rear, Flat Chassis, Swiss 7075 T6)  [XR-354022]

Rear 2-speed upper mount for GTX flat chassis

This XRAY 354022 aluminium rear center upper mount is an RC-scale replacement part intended for GTX flat-chassis layouts. Machined from Swiss 7075 T6 aluminium, the component stiffens the rear center mounting point for the 2-speed gearbox and helps preserve accurate gear alignment under higher loads.

Designed for precision fitment, the part reduces flex at the gearbox interface and improves thermal transfer away from the transmission housing. These traits support more consistent 2-speed engagement by minimising drivetrain deflection and helping maintain gear mesh during aggressive throttle and braking inputs typical in competitive RC track use.

From a tuning perspective this mount is a direct way to change rear driveline stiffness without altering suspension geometry. Stiffer mounting can reduce shifting inconsistency caused by chassis twist, while softer setups may tolerate more compliance; use this mount as part of an overall setup adjustment rather than a standalone fix.

If your goal is improved drivetrain stability on a GTX flat chassis, this machined aluminium upper mount provides a direct upgrade path; check fitment to existing gearbox mounts and repeat post-installation checks on shift consistency before finalizing setup changes.
