- Structural Integrity: Forged construction provides vastly superior tensile strength and thermal resistance to easily withstand the rigorous demands of racing and high-RPM use.
Custom Machining & Installation Notes
- Custom Camshaft Valve Clearance: For builders running aggressive, high-lift, or high-duration aftermarket camshaft profiles, custom piston notching service is available to ensure adequate valve-to-piston clearance. Please see our Notch Labor service for more details or to add this machining service to your build.
- Bore Inspection: Your cylinder block must be precision bored and honed to exactly 93.00mm to achieve the critical piston-to-wall clearances required for high-performance forged alloys. Always provide these pistons to your automotive machinist prior to final block honing.
