Key Points on the XRAY 305921 Narrow Pinion

The XRAY 305921 Narrow Pinion Gear is intended for modelers seeking consistent gear performance in T4 series cars. Crafted from aircraft-grade duraluminum, it trims 1.5mm in width and cuts about 25 percent of weight compared with standard pinions to reduce rotating mass.

Precision Gearmaking for Minimal Runout

Turned on XRAY's precision gear machines, this narrow pinion holds tight tolerances to ensure minimal runout and strong concentricity. The chamfered teeth and specialised hardcoat treatment increase durability and help keep tooth profiles accurate over time.

Smooth Operation with XRAY Spur Matches

Paired with XRAY spur gears, this pinion helps lower throttle on/off noise and contributes to a smoother driveline feel. It is a direct-fit upgrade suited to tuners seeking quieter, more predictable gear engagement.
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 this pinion fit the T4 2017 Specs?

Yes, the XRAY 305921 Narrow Pinion is compatible with the T4 series including T4 2017 Specs when the pinion interface matches the chassis specifications.

Are there any setup changes when switching to a narrow pinion?

You should check and set correct gear mesh after fitting, and verify there is no interference with surrounding components. Narrower pinions can alter mesh feel so small adjustments are common.

What advantages does the hardcoat provide?

The hardcoat increases surface hardness to resist wear and maintain tooth geometry, helping the pinion hold consistent engagement under repeated use.
