XRAY 348418 18T Pinion for Consistent Gear Engagement

The XRAY 348418 18T Aluminum Pinion Gear provides steady, predictable mesh for racers and hobbyists. Machined from 7075 T6 aluminium and treated with a hard coating, it keeps tooth profiles intact under race loads and reduces premature wear.

Stable Running and Accurate Teeth

Its larger form factor gives extra clearance allowing a wider range of standard engines to be used. Produced on precision gear machinery, the pinion offers accurate tooth spacing and minimal runout for smoother operation. The internal fine threads ensure secure mounting on both standard and lightweight XCA clutchbells.

Simple Identification and Ratio Tuning

Each pinion carries an etched tooth count for quick selection when changing gearing at the track. Available in common sizes, it helps you tune final drive ratios to suit different circuits and driving preferences.

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.

Is this suitable for track and practice use?

Yes, the hard-coated 7075 T6 construction is aimed at regular use and sustained performance across practice and race days.

Can I change tooth count easily between sessions?

The etched tooth markings make it quick to identify and swap pinions so you can alter gear ratios between sessions with minimal fuss.

Does the coating affect fitting tolerances?

The hard coat is thin and applied to maintain profiles, so fitting tolerances remain within normal limits for XCA clutchbell compatibility.

What should I inspect after a heavy run?

Check tooth edges for chips, confirm mesh and backlash, and clean any embedded grit from the surface to preserve the coating.

Are there recommended gear combinations to try first?

Begin with commonly used pairings for your car class and adjust by one or two teeth to find the best compromise between acceleration and top speed for your track.
