King Chevrolet SBC 307CI 350CI & Gen III/IV 0.020in Oversize Tri-Metal Connecting Rod Bearing Set

The King Engine Bearings CR807XPN020X is a set of XP-Series rod bearings designed for extreme performance loads. These bearings are developed for performance applications utilizing aftermarket forged steel crankshafts that endure high loads.

King XP-Series rod bearings feature an enhanced tri-metal construction with copper-lead, a nickel plate barrier, and a lead/tin/copper babbit overlay. They are manufactured with exceptional stability and durability, maintaining wall thickness tolerances of +/- .0001 inches. The bearings are narrowed on the crank cheek side and have increased crush height for better contact, heat transfer, and reduced spin potential in high-rpm engines.
