Overview of the XRAY 305921 Narrow Pinion

The XRAY 305921 Narrow Pinion Gear is built for modelers who prioritise precise gear behaviour in their T4 series vehicles. Constructed from aircraft-grade duraluminum, it saves roughly 25 percent in weight and trims 1.5mm from the standard width to cut rotating inertia.

Machined for Excellent Concentricity

Using XRAY's dedicated gear machining processes, this narrow pinion holds very tight tolerances to ensure reliable concentric rotation. The chamfered teeth and hardcoat layer protect the contact surfaces and help maintain accuracy over many running sessions.

Quiet Running with XRAY Spur Combinations

When used with XRAY spur gears, this pinion helps reduce on/off throttle noise and improves the smoothness of the driveline. It is a straightforward upgrade for tuners seeking steadier throttle response and less gear buzz.
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.

Is the XRAY 305921 compatible with older T4 chassis?

The XRAY 305921 is intended for the T4 family; many earlier T4 variants that share the same pinion interface will accept it, but verify fit against your chassis and spur gear first.

Will the hardcoat require a running in period?

The hardcoat increases surface durability and generally does not need a special break-in. Confirm proper mesh and run lightly at first to ensure smooth engagement.

What setup tips improve pinion life?

Set correct backlash, avoid excessive binding, and keep gears free of abrasive debris. Regular inspections and correct alignment will keep the pinion performing well.
