King Engine Bearings XP Series Performance Connecting Rod Bearing Set

The King Engine Bearings XP Series Performance Connecting Rod Bearing Set is a line of high-load rod bearings (also called engine rod bearings or con rod bearings) built for performance and racing engines. King makes only engine bearings. The XP Series uses advanced metallurgy and bearing geometry to handle extreme loads. It was developed for performance applications with forged steel aftermarket crankshafts that run high loads for long periods.

Key Features:

• Enhanced tri-metal construction: a copper-lead layer, a nickel barrier and a lead/tin/copper overlay are bonded to a steel backing for stability and durability.
• Tight wall tolerances: King's "Bull's Eye" quality control holds bearing wall thickness very close, with shells matched to 0.0001 in.
• Increased crush height: improves bearing-to-bore contact and heat transfer. It also reduces the chance of the bearing spinning at high RPM.
• Chamfered crank cheek side: a relief on the crank cheek side supports use in high-RPM builds.
• Optimized oiling and load distribution: medium eccentricity helps spread load and supports oil flow.
• Design options: depending on the part number, bearings may come narrowed, with or without dowel holes, and in coated or uncoated versions.

XP Series rod bearings suit circle track, off-road, offshore and other demanding racing or high-performance builds. They also work well in street/strip engines that need extra load capacity and durability.
