GTX Centre 2-Speed Lower Mount Upgrade for 2026 Flat Chassis - XRAY 354017  [XR-354017]

Low mount for GTX centre gearbox stability

This aluminium lower mount is an RC-scale upgrade for GTX flat chassis designs, intended to firm up the centre drivetrain and improve the reliability of 2-speed shifting under load. The stiffer connection helps prevent movement that can interrupt gear engagement during long runs.

CNC-machined from Swiss 7075 T6 aluminium and black coated for wear resistance, the part is produced to tight tolerances for consistent assembly. It concentrates on structural reinforcement and heat dispersion rather than altering transmission ratios or motor output.

Fitting tips: remove debris and burrs from mating surfaces, attach to the original flat chassis mounting points, and use the chassis manufacturer's recommended torque for aluminium fastenings to prevent distortion. Test engagement under both idle and loaded conditions after installation.

Setup role: suited to drivers seeking consistent transmission behaviour in endurance or high-load scenarios. It works best when paired with a properly adjusted gearbox and routine drivetrain upkeep.

As a precision aluminium replacement, this mount enhances drivetrain rigidity and shift predictability for GTX flat-chassis setups, delivering a durable option for serious racers.
