Key Features

• High-strength overlay plate designed with reduced thickness for superior fatigue resistance.
• Hardened steel backs on all rod bearings enhance support and retention within the housing.
• Increased crush design improves bearing retention, ensuring they stay securely in place under pressure.
• Eliminates flash plating on the back for better heat transfer and grip between bearings and housing.
• Enhanced eccentricity compensates for bore distortion at high RPM, promoting effective hydrodynamic oil films.
• 3/4 grooved main bearings optimize load carrying surface area, maximizing oil flow to conrod bearings.
• Consistent wall tolerances help maintain precise clearances for optimal performance.
• Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
