King Engine Bearings CR1305XPC Performance Rod Bearing Set

The King Engine Bearings CR1305XPC is a high-performance connecting rod bearing set from King's elite XPC race series. Engineered for extreme racing conditions, these bearings feature King's advanced pMaxBlack™ tri-metal construction with an additional nano-composite polymer coating for superior wear resistance and durability.

Advanced XPC Technology:

• Nano-composite polymer coating applied over pMaxBlack™ overlay enhances wear resistance without adding thickness
• 24% stronger overlay and 17% more fatigue strength compared to conventional tri-metal bearings
• Tri-metal construction layers copper-lead with nickel plate barrier and lead/tin/copper babbitt overlay on steel backing
• Bull's Eye Tolerance™ maintains wall thickness at an industry-leading ±0.0001 inch for consistent clearances
• U-Groove™ design uses 90-degree oil grooves to increase bearing surface area and load capacity

Performance Features:

• Designed for high-load, extended-duration racing with forged steel crankshafts
• Increased crush height improves bearing-to-bore contact and heat transfer
• Reduces spin potential in high-RPM applications
• EccentriX™ technology optimizes load distribution and oiling characteristics
• ElliptiX™ oil slot design improves oil ingress without compromising load capacity

King's XPC series bearings represent the pinnacle of race bearing technology, developed through extensive testing in the most demanding motorsports applications. These bearings deliver the reliability and durability that professional engine builders and racers depend on for maximum performance.
