Thin Precision for Competitive Tracks

The XRAY 305971 Narrow Pinion Gear is built for racers seeking tighter control and reduced rotating weight. Made from aircraft-grade aluminum, it measures 1.5mm thinner and is roughly 25% lighter than standard pinions, helping lower the car's overall mass without compromising strength.

Precision Machining

Manufactured on high-precision gear equipment with strict tolerances, this pinion delivers excellent concentricity and smooth tooth engagement. The chamfered teeth and hardcoat surface treatment improve wear resistance for repeated track sessions.

Easy Fit and Quiet Operation

Designed to pair with a wide selection of spur gears, including XRAY spur gears, the narrow profile helps smooth throttle transitions and reduces drivetrain noise. It installs straight from the box and requires no extra modification for typical RC setups.
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 fit non XRAY spurs with the same module?

Yes. As long as the spur gear matches the same module and tooth profile, the XRAY 305971 will mesh correctly with many third party spurs. Check tooth count and module before fitting.

How should I check mesh after installation?

Set a proper pinion to spur mesh using feeler gauges or the paper method, then run a short test at low throttle. Recheck after a few laps since hardcoat surfaces bed in slightly.

Does the narrow design change acceleration?

Reducing rotating mass helps transient response, so you may notice crisper acceleration and improved handling. Effects vary by setup, so try it on your usual track to confirm gains.
