What the XRAY 305921 Narrow Pinion Offers

The XRAY 305921 Narrow Pinion Gear suits drivers wanting tighter rotational accuracy in T4 class cars. Forged from aircraft-grade duraluminum, it is 1.5mm slimmer and around 25 percent lighter than many standard pinions, reducing rotational inertia for crisper response.

Superior Tolerance Control

Manufactured on XRAY precision gear equipment, the narrow pinion is held to strict tolerances to achieve excellent concentricity. Combined with chamfered teeth and a tough hardcoat finish, the gear is built to resist wear during repeated track sessions.

Designed to Work with XRAY Spur Gears

This pinion is optimised for use with XRAY spur gears to cut throttle chatter and smooth the drivetrain. It is a plug-in option that helps competitors refine mesh and reduce audible gear noise.
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.

Which cars use the XRAY 305921 pinion?

The XRAY 305921 is made for the T4 series platform and fits T4 2017 Specs compatible setups; always check pinion seating and clearance on your specific chassis.

Can I change spur sizes with this pinion?

Yes, mixing spur sizes is possible but confirm tooth count and pitch match and then set the correct mesh. Changing spur size will alter overall gearing and may need motor or timing adjustments.

How do I check concentricity after fitting?

Spin the wheel or spur assembly by hand and observe for wobble, check mesh across several tooth engagements, and feel for binding. A dial indicator on the shaft can give a precise measurement if needed.
