Serpent 802517 Centax 3-Gear Aluminum Pinion 17T - Track Tuned Replacement  [SER802517]

Track-Ready Aluminum Pinion for the 720-09 Chassis

The Serpent 802517 Centax 3-Gear Aluminum Pinion 17T is built to tighten up the gearing on vintage 720-09 200mm GP cars. Machined from quality aluminum, this 17-tooth pinion balances strength with low weight to deliver dependable power transfer on paved and carpet tracks. It is a straightforward upgrade for drivers who want smoother acceleration without sacrificing durability.

Low Rotational Mass for Improved Acceleration

The lightweight aluminum construction reduces rotating mass while keeping the gear robust under load. The 17-tooth count offers a sensible compromise between top speed and torque, helping your car launch cleanly out of corners. Fitment with the 720-09 200mm GP chassis is direct when shaft and bore match, making installation quick for weekend race prep.

Built to Withstand Practice and Racing

This pinion helps manage heat better than some softer materials and stands up to repeated running sessions. For club racers and dedicated hobbyists, it gives predictable drivetrain behavior lap after lap. Regular inspection and basic maintenance will keep the gear running reliably in both practice and event conditions.
