XRAY 305991 narrow pinion for dependable gearing

The XRAY 305991 Aluminum Narrow Pinion Gear is a 41T alloy pinion made to combine durability with low mass. The hardcoated finish strengthens the tooth surfaces while the duraluminum construction reduces inertia for crisper throttle response.

Precision cut teeth for consistent engagement

Turned on high-precision gear equipment, the XRAY 305991 maintains tight tolerances and true runout values. The chamfered tooth form and uniform hardcoating support stable engagement with spur gears and can reduce audible drivetrain noise when used with XRAY components.

Optimised for lower inertia and faster acceleration

From the 40T to 50T 64-pitch series, this 41T model is thinner by 1.5mm and about 25% lighter than many standard pinions. The slim profile eases rotational load and helps your car accelerate more responsively in both practice and competition.
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.

Does the XRAY 305991 require a special motor shaft size?

No special shaft is needed beyond matching bore diameter. Verify your motor shaft and ensure the set screw secures the pinion without slipping.

How should I check for wear on this pinion?

Inspect tooth faces for flattening or chipped edges and monitor drive feel. Heavy wear or broken teeth warrants replacement to avoid spur gear damage.

Is this pinion a good upgrade for competitive racing?

Its low mass and hardcoated finish make the XRAY 305991 a sensible upgrade for improved acceleration and longer service life, especially when matched with precise spur gears.
