King HP-Series rod bearings were developed mainly for drag race applications needing a material harder than the Babbitt top layer. These applications demanded a structure that could withstand high loads for short durations and still offer higher embeddability and compatibility. In response, King developed the HP-Series, featuring the Alecular metal structure. The HP-Series is also suited for many performance applications with nodular cast iron crankshafts, such as street, strip, and some levels of Circle Track racing. Order the set recommended for your vehicle. HP-Series bearings are particularly suitable for the following cases: * When a tri-metal bearing's Babbitt overlay extrudes over the sides, migrates to one end, or is physically removed by the crankshaft * When the intermediate layer of a tri-metal bearing is exposed, damaging the crank journal and requiring expensive grinding or replacement * When contaminants enter the oil stream, scratching and damaging the crankshaft journals

King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods. King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.

King SI-Series main bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow. Order the bearing set designed for fitment on your make and model.
