Precision Gearwork for Vintage Drivetrains

The XRAY 355054 Center Differential Spur Gear 42T is designed for hobbyists wanting dependable gear engagement and longevity. Forged from HUDY steel, this 42-tooth spur suits Vintage XB Series differentials where accurate tooth profiles are required.

German Tooling and Exact Tooth Profiles

Manufactured on top-tier German machinery, each spur gear receives precision grinding for exact tooth shape and consistent contact with differential outdrives. The laser-etched 42T label helps when sorting parts during a service.

Robust Thermal Treatment

Careful heat treatment increases hardness through the whole part rather than only at the surface, lowering wear rates and extending useful life compared with generic gears used in similar applications.
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 special lubrication required for this spur gear?

Use a quality diff grease or oil suited to your setup; the gear material is robust but correct lubrication is key to quiet running and long life.

Will this 42T change my final drive ratio?

Changing the center spur may alter ratio if your pinion differs; check tooth counts across the drivetrain to maintain the desired ratio and engine characteristics.

Can I reuse the original hardware when fitting the gear?

In most cases original screws and spacers are fine, but inspect threads and replace any worn fasteners to ensure secure, rattle-free mounting.
