Key Features

• High-strength overlay plate with reduced thickness enhances fatigue resistance.
• Hardened steel backs on all rod bearings improve support and retention within the housing.
• Increased crush for superior bearing retention, ensuring they stay put under stress.
• Flash plating removal on the back facilitates better heat transfer and grip with the housing.
• Enhanced eccentricity compensates for bore distortion at high RPM, aiding in hydrodynamic oil film formation.
• 3/4 grooved main bearings optimize load-carrying surface area and improve oil flow to the conrod bearings.
• Tight, consistent wall tolerances help maintain precise clearances for better performance.
• Enlarged ID chamfers accommodate large fillet radii on performance crankshafts.
