XRAY 305920 Precision Narrow Pinion 20T/48 Hard Coated  [XR-305920]

Precision machining in the XRAY 305920 narrow pinion

The XRAY 305920 Narrow Pinion Gear is tailored for T4 2017 Specs cars where accurate gear alignment and lower rotating weight matter. Fabricated from aircraft-grade duraluminum, this pinion is 1.5mm narrower and about 25 percent lighter than many standard pinions, helping to reduce inertia on the drivetrain.

Superior concentricity and hardcoat protection

Produced on XRAY's specialised gear machinery, the narrow pinion benefits from very tight machining tolerances to deliver improved concentricity. The gear edges are chamfered and treated with a hardcoating process that helps preserve the tooth form under repeated use.

Reliable mesh and quieter running

Made to engage smoothly with spur gears, the XRAY 305920 Narrow Pinion Gear works especially well with XRAY spur gears to achieve consistent contact patterns and lower audible gear noise for a tidier drivetrain sound.
