King Engine Bearings CR 807XPND 001 Connecting Rod Bearing Set Chevy SBC 307ci 350ci Gen III/IV

The King Engine Bearings CR 807XPND 001 is a connecting rod bearing set engineered for Chevrolet Small Block (SBC) 307ci and 350ci engines, as well as Gen III/IV LS-platform applications. King Engine Bearings is a globally recognized OEM and performance bearing manufacturer known for producing precision-engineered bearings to exacting tolerances.

This set features King's XP (Extra Performance) series construction, which incorporates a narrowed (ND) bearing profile. The narrowed design increases oil flow to the bearing surface, reducing friction and improving lubrication under high-load, high-RPM conditions — making these bearings a preferred choice for performance builds, street/strip applications, and engine rebuilds.

Key Features:

• XP (Extra Performance) tri-metal bearing construction for enhanced durability and load capacity
• Narrowed (ND) profile promotes increased oil flow and reduced operating temperatures
• Precision-manufactured to strict OEM tolerances for consistent fitment and reliable performance
• High-strength steel backing with premium overlay for fatigue resistance
• Compatible with Chevrolet Small Block 307ci and 350ci engines and Gen III/IV LS platforms
• Designed for performance street, racing, and high-output engine applications

King's XP series bearings are machined to tight dimensional tolerances and feature eccentricity profiles that ensure optimal oil film distribution across the bearing surface. These rod bearings are a direct-fit replacement or upgrade for factory bearings in supported applications, and are well-suited for use during engine overhauls, rebuilds, or performance upgrades.
