Precision Centax Pinion by Serpent

The Serpent 903801 Centax gear-pinion fits the XLI Gen2 clutch and serves as a durable aluminium 20-tooth replacement. Built for consistent meshing and efficient torque transfer, this pinion is suited to club racers and weekend tuners aiming for reliable drivetrain behaviour. It balances strength and lightness for everyday race use.

Can I use this pinion with aftermarket spur gears?

Yes, the Serpent 903801 works with common spur gears that match the pitch and tooth profile, but check tooth count and mesh before running.

Is any break-in needed for the aluminium pinion?

A short, low-load break-in run helps seating the teeth. After that, inspect the mesh and make small adjustments to ensure smooth engagement.

How do I check gear mesh with XLI Gen2?

Fit the pinion, place the spur on the shaft, set a snug but not tight mesh using a paper shim method, then rotate to confirm even contact across the teeth.

Are replacement parts available if the pinion is damaged?

Serpent spare parts channels typically list direct replacements like the 903801. Keep a spare pinion on hand if you race frequently.
