Features

• High strength overlay plate with reduced thickness enhances fatigue resistance, ensuring longevity under stress.
• Hardened steel backs on rod bearings improve support and retention, keeping your bearings secure in the housing.
• Increased crush for better bearing retention, which is crucial during high-load scenarios.
• Elimination of flash plating on the back promotes better heat transfer and maximizes grip between bearings and housing.
• Enhanced eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
• 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the conrod bearings.
• Tight, consistent wall tolerances allow you to maintain precise clearances, critical for performance engines.
• Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
