1, Our Crankshaft. Are 100% interchangeable with OEMs.

2, Nitriding Heat treatment on all the surface of crankshaft, which will result in excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. Overall life expectancy increased by 30%, comparing with others with induction hardening heat treatment.

3, Compared with OEM SPM, we increase the oil groove to make the bearing more fully lubricated and increase the bearing life by more than 15%.

4, All parts are going through extra 2nd QC process ensure highest quality integrity and smooth parts alignment.

5, Our Gear set comes from same mfg. as OEM SPM.

6. Made with AISI 4140 material, and induction hardening heat treatment, and go through final grinding machining process.   This will result in significantly Increased wear resistance, Increased strength and fatigue life;

7. Ground gears are known for quality, durability, process efficiency, and resilience. They can carry maximum loads and are more durable compared to non-ground gears, they are significantly quiet and suitable for use under high-speed rotation, In addition, grinding gears after quenching (heat treatment) makes it possible to produce gears that are superior in both strength and precision.

8. All parts are going through extra 2nd QC process ensure highest quality integrity and smooth parts alignment.
