Race-Focused Crankshaft for NT18 Engines

When every lap counts, drivetrain parts need to be precise. The XRAY 611401 crankshaft is machined for repeatable performance and engineered to tolerate the demands of fast nitro setups.

Why precision improves lap times

Less friction and better balance reduce parasitic losses, helping the NT18 engine deliver power more cleanly. That improved efficiency can translate into steadier throttle control and marginally better acceleration out of corners.

Material and wear resistance

Built from hardened steel and finished with exact CNC processes, this crankshaft offers resistance to scoring and deformation. The robust construction helps maintain bearing alignment and reduces the chance of mid-event failures.

Fitment and tuning considerations

Installation follows standard engine service procedures. Tuners will find the crankshaft stabilises rpm behaviour, which can simplify jetting decisions and make engine response more predictable during setup.

Specifications

  • Type: CNC-Machined Crankshaft
  • Compatibility: NT18 Engines
  • Material: Hardened Steel
  • Application: High-Performance Nitro Racing

A practical, race-ready replacement that supports consistent engine output and reduced wear for competitive NT18 cars.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Does this crankshaft need bedding in?

A short running period at varied loads helps seat bearings and mating surfaces, after which you should recheck clearances and tightness.

Are any head or piston mods required?

No special modifications are necessary; the crankshaft is designed to match NT18 engine geometry and standard components.

How does this part affect maintenance intervals?

Because it resists wear, it can help extend the interval between major overhauls, but routine checks and oiling remain essential.

Can I use this crankshaft in a converted or custom engine build?

If the build follows NT18 crank dimensions and bearing spacing, the crankshaft may be suitable; verify clearances before final assembly.

What signs indicate the crankshaft needs replacement?

Look for scoring, lateral play, or unusual vibration; any of these symptoms suggest the crankshaft or related bearings should be inspected and possibly replaced.
