Serpent 903799 18T Aluminium Pinion Gear for XLI Gen2  [SER903799]

Precision Aluminium Pinion for XLI Gen2

Serpent 903799 is a purpose-made aluminium 18T pinion designed to complement the XLI Gen2 chassis. The lightweight construction reduces rotational inertia while still delivering the strength needed for competitive running.

Lightweight but Robust Design

The aluminium construction helps cut weight at the motor end, translating to snappier throttle response and reduced load on bearings. The finished teeth are machined to tight tolerances to withstand repeated on-track use.

Exact Match for XLI Gen2 Drivetrain

Engineered to mesh neatly with the XLI Gen2 spur, this 18T pinion promotes even tooth contact and steady power transfer. Proper fitment reduces backlash and keeps drivetrain temperatures under control.

Ideal for Tuneups and Race Prep

Whether dialling in gearing for a club meeting or refreshing your race kit, the Serpent 903799 makes a straightforward upgrade. It suits hobbyists wanting a clean, low-mass pinion that is race ready after a quick check of gear mesh.
