Durable Hollow Layshaft Built for Racing

The central component is a lightweight hollow middle layshaft made from HUDY shaft steel and heat-treated for added strength, giving dependable service under racing loads.

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 replace the stock 2-speed in older RX cars?

Yes, this set is made to match the layout of older RX series transmissions and can replace worn 2-speed assemblies on those models. Always verify fit with your specific chassis revision before fitting.

What basic tools do I need to fit the kit?

You will need standard RC tools such as screwdrivers, hex drivers and pliers for bearing and gear work. A threadlocker and light grease are useful for final assembly.

How often should I service the one-way bearing?

Inspect the one-way bearing periodically for play and smooth rotation; cleaning and relubrication every few race meetings will extend life, depending on conditions and usage.
