King Engine Bearings Tri-Metal Connecting Rod Bearing Set

King Engine Bearings Tri-Metal Connecting Rod Bearing Sets are precision-made rod bearings for engine rebuilds, repairs, and performance builds. Tri-metal construction layers a steel backing, a copper-based intermediate layer, and a soft overlay. The result is a bearing that balances load capacity, conformability, and wear resistance. Also known as rod bearings or con rod bearings, these sets are a core part of any engine rebuild.

Key Features:

• Tri-metal construction: A steel back, a copper-based bearing alloy, and an overlay work together to carry high loads and resist fatigue.
• Bull's Eye Tolerance™ manufacturing: King uses this process to control wall thickness. The aim is consistent shell-to-shell clearance.
• Performance options: King's XP and XPC series use pMaxBlack™ technology. This is a tri-metal structure King describes as harder than conventional tri-metal race bearings. It also has a factory-applied nano-composite polymer coating for added wear resistance.
• Built for demanding use: Higher-performance versions are designed for racing and high-load applications. They are meant to cope with extreme loads, high RPM, and oil starvation conditions.
• OE-style replacement: Standard CA and CP series tri-metal bearings are suitable for conventional OE replacement in medium-load engines.

King Engine Bearings has a long record in bearing design and materials development. Its range includes Alecular alloys, silicon-reinforced aluminum, and advanced tri-metal structures. Choose the series, application, and size that match your engine and crankshaft journal requirements. Always measure bearing clearances during installation.
