Precision 2-Speed Transmission Solution for Vintage RX Series by XRAY 345500

For restorers and racers working with older RX series cars, the XRAY 345500 2-Speed Transmission Set supplies a full replacement package. It is configured to match the requirements of earlier RX series layouts for easy installation.

46T and 49T Spur Gears with Tight Engagement

The kit contains 46T and 49T molded composite spur gears engineered for dependable tooth contact. Together with the included 2nd gear shoe set and alloy gear holders, which house integrated bearings, they provide stable gear alignment.

Heat-Treated Hollow Layshaft for Longevity

The hollow middle layshaft is constructed from HUDY shaft steel and has been heat-treated to increase resistance to wear and bending, supporting consistent transmission performance.

Swiss 7075 T6 CNC Adapter and Hand-Ground Bearing

The 2-speed gear adapter is CNC-machined from Swiss 7075 T6 aluminum to ensure correct seating of the one-way bearing. The hand-ground, high-quality one-way bearing helps eliminate wobble and keeps spur gears running true.

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.

How do I confirm fit before buying?

Compare your chassis mounting points and shaft clearances with the original transmission dimensions. If possible review parts diagrams for your specific RX revision to confirm compatibility.

Is the one-way bearing preassembled?

The kit includes the hand-ground one-way bearing but final assembly into the adapter is required during installation to ensure correct preload and alignment.

Any tips for extending gear life?

Keep gear mesh set correctly, check for contaminated grease, and replace worn bearings promptly. Regular inspections after hard sessions will help spot issues early.
