Rigid centre tower for consistent shifts

This XRAY 354021 aluminium upper mount is a CNC-machined centre 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.

Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this alter shift timing or engagement feel?

By reducing chassis tower flex, the mount promotes repeatable shift engagement. Drivers may notice more consistent timing and a firmer shift feel compared with a softer stock tower.

Can I adjust brake pad alignment after fitting?

Yes. The integrated caliper interface sets a baseline alignment; minor shimming or pad shims can be used to fine tune contact and clearance without changing the main mount.

Does this part change chassis flex characteristics?

Adding a stiff aluminium tower reduces local flex in the drivetrain area, which can shift handling balance. Expect tighter drivetrain response; adjust suspension settings to compensate if needed.

Is the mount compatible with aftermarket gearbox internals?

Interfaces are standard to GTX gearbox geometry, but confirm clearances when using larger or modified internals. Trial fit and check for interference before final assembly.
