XRAY 305991 narrow aluminium pinion built for precision

The XRAY 305991 Aluminum Narrow Pinion Gear is a 41-tooth unit tailored for hobbyists who value consistent gearing and longevity. Hardcoating boosts surface durability while the use of aircraft-grade duraluminum trims weight to aid quicker spool up.

Precision manufacturing for steady performance

Machined on advanced gear equipment, the XRAY 305991 achieves tight concentricity tolerances that lead to stable mesh. The treated tooth edges and uniform hardcoat support longer service life and quieter running when matched with compatible spur gears.

Designed thin and light for nimble handling

Available across a 40T to 50T 64-pitch lineup, this 41T pinion is manufactured 1.5mm thinner than many stock options and is around 25% lighter. The reduced inertia lowers drivetrain load and helps the car accelerate more responsively.
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 XRAY 305991 fit my 64-pitch setup?

If your spur gear is 64-pitch it will mesh. Check the pinion bore and shaft diameter to ensure correct mounting and secure set screw seating.

Does hardcoating change gear trimming or break-in?

The hardcoat increases wear resistance so break-in is minimal. Confirm proper mesh and run gently at first to settle the gear pairing.

Is this pinion suitable for both touring and off-road cars?

The narrow profile and light weight suit many on-road and light off-road applications, but always match tooth count and pitch to your spur and driving style.

How much weight difference can I expect?

Compared to typical alloy pinions, the duraluminum construction is about 25% lighter, which can noticeably reduce rotating mass and improve acceleration.
