GTX 2026 Centre Upper Mount, Rear 2-Speed - XRAY 354022  [XR-354022]

Rear upper mount for 2-speed gearboxes on GTX chassis

The XRAY 354022 aluminium rear centre upper mount is supplied as a precision replacement for GTX 2026 flat-chassis systems. Made from Swiss 7075 T6, the part stiffens the rear centre attachment for the 2-speed gearbox and helps keep gear mesh accurate under higher loads.

Precision machining reduces flex where the gearbox meets the chassis and assists thermal transfer away from the transmission housing. Those improvements aid more consistent two-speed engagement by limiting drivetrain deflection during heavy acceleration and braking typically encountered on race circuits.

From a setup angle this mount is a clear method to change rear driveline stiffness without altering suspension geometry. A firmer mount can cut back on shifting inconsistency caused by chassis twist, whereas a softer approach retains compliance; include this part in a full setup review rather than relying on it alone.

When seeking better drivetrain stability on a GTX 2026 flat chassis, this machined aluminium upper mount presents a direct upgrade route; always confirm fitment and run post-installation checks to ensure shift consistency before competitive use.
