XRAY 348418 18T Hard-Coated Aluminum Pinion Gear  [XR-348418]

Precision 18T Pinion by XRAY 348418 for Reliable Drivetrain Performance

The XRAY 348418 18T Aluminum Pinion Gear is built for club and competitive racers who need durable, accurate gearing. Machined from 7075 T6 aluminium and given a hard coat, this pinion resists wear and keeps gear engagement precise over many running sessions.

Engineered Tooth Geometry

Its oversized form lets the engine sit further from the bulkheads, providing clearance for a wide range of standard engines. Produced on high-end gear machines, each pinion features true running and carefully shaped teeth to reduce vibration and promote smooth power delivery. Internal fine threads make fitting quick and secure on both standard and lightweight XCA clutchbells.

Clear Markings and Flexible Ratios

Each gear is laser-etched with its tooth count so you can change ratios fast at the track. Offered in common sizes, this pinion helps you tune final drive ratios to match different circuit conditions and driving styles.

A practical upgrade for racers wanting a tougher, more consistent pinion, the XRAY 348418 provides long life and precision that supports confident tuning on race day.
