King Engine Bearings CR4104XPCSTDX XP-Series Coated Connecting Rod Bearing Set

The King Engine Bearings CR4104XPCSTDX is a high-performance connecting rod bearing set engineered for Audi and Volkswagen engines with ABB, ABM, ADP, PP, and RN engine codes. This set features King's advanced pMaxKote nano-composite polymer coating applied over the pMax Black overlay during the manufacturing process, delivering enhanced protection for demanding performance applications.

Advanced Coating Technology:

• Factory-applied nano-composite polymer coating enhances wear resistance and protects bearings during metal-to-metal contact
• Proven protection against metal-to-metal contact and erosive effects of cavitation
• Enhances wear resistance without changing the bearing's original precision wall thickness dimension
• Ceramic nano-composite particles function as a fourth layer providing superior build protection

XP-Series Performance Features:

• Advanced metallurgical and geometric technologies designed to meet extreme performance loads
• Unique tri-metal structure for race applications
• 24 percent stronger overlay and 17 percent more fatigue strength using SecureBond micro process
• Enhanced tri-metal construction layers copper-lead with nickel plate barrier and lead/tin/copper Babbitt overlay over steel backing
• Wall thickness tolerances maintained at an exceptional +/- .0001 inch
• Narrowed on crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications

STDX Sizing Specification:

The STDX designation indicates standard size with .001 inch extra clearance for enhanced oil film stability, making this set ideal for performance rebuilds, boosted applications, and engines operating under high loads for extended periods. The set includes 4 pairs of bearings for complete connecting rod replacement.

Developed specifically for performance applications using forged steel aftermarket crankshafts that produce high loads for extended periods, these bearings represent King's commitment to bearing specialization and race-proven technology.
