OVERVIEW

• HIGH STRENGTH OVERLAY PLATE with reduced thickness for improved fatigue properties
• HARDENED STEEL BACKS on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• INCREASED CRUSH for improved bearing retention
• ELIMINATION OF FLASH PLATING on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
• INCREASED ECCENTRICITY to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• 3/4 GROOVED MAIN BEARINGS to optimize bearing load carrying surface area and oil flow to the conrod bearings.
• TIGHT CONSISTENT WALL TOLERANCES to help you maintain consistent clearances.
• ENLARGED ID CHAMFERS on bearing edges where required to accommodate large fillet radius on performance crankshafts.
