Trimetal race-grade construction for enhanced strength and load capacity
High-strength overlay with reduced thickness for improved fatigue properties
Hardened steel backing improves structural integrity and bearing retention
Increased crush and eccentricity to compensate for high RPM bore distortion
Flash plating eliminated on the backing for superior heat dissipation
Precision wall tolerances for consistent bearing clearances
Suitable for both naturally aspirated and turbocharged EJ engines
Drop-in fit – no machining required
