Race-focused pinion gear from Serpent

RC racers who want sharper gear response will appreciate the Serpent 903805 - Aluminium Centax Pinion Set XLI Gen2, which combines light construction with tight machining tolerances. It is made to help fine tune drivetrain behaviour for improved on-track control.

Engineered for speed and control

The Centax pinions are machined from quality aluminium to keep strength high while cutting excess weight. That balance helps maintain agility and sharper acceleration during competitive runs.

Wide fitment for different setups

The Serpent 903805 set fits a broad range of Centax-compatible systems, making it a practical upgrade for hobbyists running several vehicles. Installation is straightforward for common clutch-type drivetrains.

Material benefits for racers

Aluminium pinions are chosen for their mix of lightness and durability. Using aluminium reduces rotating mass in the drivetrain, which can translate to crisper throttle response and more consistent lap times.
