King Engine Bearings XP Series Tri-Metal Connecting Rod Bearing Set

King Engine Bearings XP Series tri-metal connecting rod bearings (also called rod bearings) are built for racing and high-performance engines. They suit engines that run forged steel aftermarket crankshafts and see high loads for long periods. King makes only engine bearings, and the XP Series applies that focus to demanding circle track, off-road, and marine use.

Key Features:

• Enhanced tri-metal construction: a copper-lead layer, a nickel barrier, and a Babbitt overlay over a steel backing.
• SecureBond adhesion process: bonds the layers for stability and durability under heavy load.
• Hardened performance overlay: a thin, metallurgically hardened overlay that resists surface fatigue and wear.
• Higher load capacity: King states the pMax Black tri-metal is harder than conventional tri-metal race bearings and carries more load.
• Tight wall thickness tolerances: King holds wall thickness to very close limits for consistent clearances and performance.
• Increased bearing height: improves bearing-to-bore contact and heat transfer, and reduces the chance of spin at high RPM.
• Medium eccentricity design: helps distribute load and improve oil flow.

Choose the child item with the part number that matches your engine and the crankshaft journal size you need. Correct oil clearance and proper installation are important for bearing life in any high-output build.
