Racing Grade 19T Pulley for XRAY NT1 Drivetrains

The 3Racing XN1-41/RE 19-tooth aluminium pulley is produced for precise drivetrain behaviour in XRAY NT1 race cars, providing reduced friction and repeatable power delivery under load. Its machined profile aids predictable gear mesh and helps drivers fine tune response during setup changes.

What setup benefits does the XN1-41/RE bring to a race pack car?

The aluminium pulley stabilises rotational inertia and reduces slop in the drivetrain, which helps deliver crisper throttle response and more consistent lap times when paired with tuned gearing.

How should I tune gear mesh when fitting this pulley?

Start with manufacturer recommended spacing, then fine tune under low load while checking for smooth engagement across full rotation; minor adjustments can reduce noise and heat build-up.

Are there recommended upgrade paths after installing this pulley?

Pair the XN1-41/RE with hardened steel gears and high-quality bearings to maximise drivetrain efficiency and durability for competitive running.
