The set includes 4 pairs of rod bearings to service all cylinders of the 4-cylinder W11B16 engine.

King XP-Series Technology:

• Tri-Metal Construction: Lead bronze layered material with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing — engineered for superior stability and durability under extreme loads
• pMaxBlack Overlay: Proprietary nano-scaled hardening process of Babbitt overlay that withstands up to 10,200 PSI load capacity
• SecureBond Process: Delivers 24% stronger overlay and 17% more fatigue strength compared to standard bearings
• Bull's Eye Tolerance™ Technology: Combines highly accurate machining, overplating, and computerized wall thickness monitoring, maintaining tolerances of +/- .0001 in.
• XP Geometry: Narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, better heat transfer, and reduced spin potential in high-RPM applications
• Oversize: +0.026mm (0.001 in.) for use with machined crankshaft journals

Developed for high-performance and racing applications that utilize forged steel aftermarket crankshafts and sustain high loads for extended periods.
