Precision and Weight Savings with XRAY 305987

Built for serious RC racers, the XRAY 305987 Narrow Pinion Gear is machined from aircraft-grade duraluminum to cut weight while keeping strength. The design trims overall mass by 25% compared to standard pinions and features a narrow profile that is 1.5mm slimmer than common alternatives, reducing rotational inertia and improving throttle response.

Manufacturing Quality and Hardcoat Protection

Each pinion is produced on a specially modified gear machine to tight tolerances, ensuring excellent concentricity. After machining, all teeth and edges are chamfered, the gears are run-in, and a hardcoat finish is applied. This process extends service life and helps preserve quiet operation, particularly when used with XRAY spur gears.

Fitment and Usage Notes

The XRAY 305987 works with a broad range of spur gears and integrates smoothly with XRAY gear sets for low-noise performance. It is well suited for upgrades or routine maintenance and arrives ready to install for dependable track performance.
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 305987 fit all 1/10 scale transmissions?

In most cases yes; the XRAY 305987 is designed for standard 1/10 scale pinion interfaces but always double-check shaft diameter and spline count before fitting.

How should I set gear mesh with this narrow pinion?

Start with a small paper shim method or feeler gauge to achieve a slight tooth-to-tooth contact, then tighten while rotating the gear to ensure smooth mesh without binding.

Does the hardcoat mean I can skip maintenance?

No, the hardcoat improves wear resistance but periodic inspection and proper lubrication of mating gears will keep performance consistent over time.
