Heavy Duty 19T Aluminium Pulley for Racers

Upgrade your setup with the Serpent 401427 19T aluminium pulley. Built for RC enthusiasts, this component uses aluminium to balance low weight with solid durability, making it useful when you want crisper gear engagement and longer service life on the track. Its design suits multiple chassis formats so you can refine drivetrain ratios and handling.

Advantages of the 19-tooth aluminium pulley

The Serpent 401427 brings a 19-tooth profile combined with precise machining to ensure steady power transfer and less drivetrain strain. Aluminium helps keep rotating mass down while resisting wear, which benefits both club racers and hobby drivers who prioritise consistency.

How do I check if this will work with my model?

Compare the pulley tooth count and bore diameter to your current parts, and consult your chassis manual to confirm fitment before purchase.

Is aluminium better than plastic for pulleys?

Aluminium typically gives improved durability and more consistent performance under load, though it may show wear differently than polymer parts.

What maintenance should I carry out?

Keep the pulley clean of grit, check for burrs or runout, and ensure belts remain correctly tensioned to extend service life.

Can I fine-balance the pulley for high speed runs?

Small balancing adjustments can help at high RPM; check for axial runout and correct any wobble before competitive runs.
