Product Description

The King XP-Series Connecting Rod Bearings (part CR4002XP) feature advanced metallurgical and geometric technologies engineered to meet extreme performance loads. Developed for applications running forged steel aftermarket crankshafts under high loads for extended periods, they're built for engines that demand more than a stock bearing can deliver.

King's innovative, race-only Xtreme Performance pMaxBlack tri-metal overlay is 24% stronger and offers 17% more fatigue strength than a typical bearing overlay, using a proprietary SecureBond micro process. The tri-metal construction layers copper-lead with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing, delivering superior stability, durability, and a load capacity up to 10,200 PSI.

This standard-size set of 4 fits the Mazda B6/B6-T/ZM/B3/B5 engine family and related Ford, Mercury, and Kia applications sharing the same block. King's advanced control measures maintain wall thickness tolerances far tighter than typical aftermarket bearings, making this a proven choice for circle track, drag racing, and other demanding motorsport applications.
