King Engine Bearings CR8063XP XP Series Tri-Metal Connecting Rod Bearing Set BMW S62

The King Engine Bearings CR8063XP is a high-performance XP Series connecting rod bearing set designed for BMW S62 engines, featuring advanced tri-metal Lead Bronze construction with a nano-scaled hardening process that withstands loads up to 10,200 PSI. Ideal for circle track, drag racing, off-shore, and other demanding applications utilizing steel crankshafts.

Advanced XP Series Technology:

• pMax Black™ tri-metal structure that is 24% harder than conventional tri-metal race bearings
• 17% more fatigue strength through the proprietary SecureBond micro-etch adhesion process
• Enhanced tri-metal construction layers copper-lead alloy with nickel plate barrier and lead/tin/copper Babbitt overlay over steel backing
• Intermediate layer features copper-based alloy strengthened by 4.5% tin with industry-leading 115HV hardness and 17,000 PSI load capacity
• Proprietary nano-scaled hardening process produces superior load capacity in the overlay

Performance Features:

• Bull's Eye Tolerance: Closest wall tolerances in the industry with all shells matched to 0.0001 inch
• Increased height improves bearing-to-bore contact and heat transfer while reducing spin potential at high RPM
• Narrowed design on crank cheek side with increased crush height for improved contact and reduced spin in high-rpm applications
• Medium eccentricity enables optimum load distribution and improved oiling
• Optimized crush height and eccentricity values through elasto-hydrodynamic analysis with industry-leading wall thickness tolerance control

Engineered specifically for high-performance applications using forged steel aftermarket crankshafts that produce high loads for extended periods. King Engine Bearings was founded in 1960 with one objective: to supply the highest quality bearings available in the marketplace, utilizing the highest quality materials and most advanced designs for complete customer satisfaction.
