XLPower Nimbus 550 Nitro Engine Shaft Set V2 : XL55NB12-1
A new design for higher precision and reliability, fully compatible with OS and YS engines.
Kit Includes
- Engine shaft (extended design, factory runout ≤0.02mm)
- Starter coupling
- Tapered washer (for clutch seating)
- Fan nut
- Small-angle taper sleeve (secure fit without over-tightening)
- 7×19×6 bearing
Key Improvements
- Improved concentricity — upper clutch bearing alignment significantly enhanced for smoother transmission.
- More reliable structure — starter coupling no longer sits inside the bearing, reducing clutch loosening risk.
- Optimised taper angle — easier installation, secure engagement without excessive tightening.
- Universal fit — compatible with both OS and YS engines, no modifications required.
- Recommended tightening torque: 16–18 Nm for secure and reliable locking.
Engineered for maximum precision and durability in 550-class Nitro systems.
