XRAY 611401 NT18 Performance Crankshaft  [XR-611401]

High-Precision Crankshaft Built for NT18 Power

For lap-to-lap consistency, the crankshaft is a key component. The XRAY 611401 uses CNC methods to produce a stable, repeatable part that helps keep NT18 engines running smoothly in race scenarios.

The role of the crankshaft in nitro engines

This part converts piston thrust into usable torque, so its balance and surface finish directly affect engine vibration and longevity. Properly made crankshafts reduce bearing stress and maintain steady engine speed under load.

Manufacturing and fit

CNC machining and hardened steel construction yield a clean, accurate finish and robust structure. The result is a crankshaft that seats properly and resists wear, reducing the need for frequent replacements in aggressive running.

Who benefits from this upgrade

Track competitors and experienced tuners will notice improved throttle control and a more predictable powerband. Hobbyists who maintain their engines will also gain from reduced wear and better long-term reliability.

Designed to deliver consistent performance and robust service life, this crankshaft is a practical improvement for NT18-powered cars.
