King Engine Bearings Main Bearing Set Tri-Metal pMaxBlack

King Engine Bearings pMaxBlack tri-metal main bearings are performance crankshaft main bearings built for racing and high-output engines. They are designed to hold up under heavy loads, high RPM and long periods of hard use. They suit circle track, drag racing, offshore and other builds that use steel crankshafts.

Key Features:

• Tri-metal construction: a copper-based intermediate layer with a hardened babbitt overlay.
• pMaxBlack overlay: a proprietary nano-scaled hardening process creates a black, fatigue-resistant bearing surface. The overlay has increased copper content for added strength and load capacity.
• SecureBond micro-etching: improves adhesion between layers and the structural integrity of the bearing.
• Precision tolerances: King's performance bearings use tight wall-thickness matching and its Bullseye clearance control.
• Radialock and Eccentrix geometry: an optimized crush height and eccentricity for better load distribution and oiling.
• Performance design details: enlarged, chamfered oil holes and a narrowed design that helps clear large-fillet cranks.

King Engine Bearings is known for engineering race-proven bearings. The pMaxBlack main bearing line gives engine builders a durable, dependable bearing for demanding applications. Each part number in this line has its own size and application details.
