Serpent 904205 Composite Spur Gear 45T M1 - Track Focused Upgrade  [SER904205]

Accurate power delivery with Serpent 904205

The Serpent 904205 Composite Spur Gear 45T M1 is engineered to improve drivetrain smoothness and longevity in 1/8 scale RC cars. Its 45-tooth profile gives predictable engagement for cleaner acceleration and steady top-end performance on race circuits.

Why composite works for racing

Composite construction trims weight while keeping strength where it matters, lowering rotating mass and easing load on the gearbox. That balance helps acceleration and reduces wear during repeated high-speed runs.

Built for 1/8 scale drivetrains

This spur gear suits a wide range of 1/8 scale chassis layouts and meshes well with multiple pinion options, giving precise tooth engagement for reliable gearing choices across track conditions.

Practical benefits for hobbyists

Whether replacing a tired part or upgrading for reduced drivetrain strain, the Serpent 904205 offers a practical way to extend component life and keep your RC running clean between services.
