King Engine Bearings CR4099XP XP-Series Connecting Rod Bearings

Part of King's premium XP line, these bearings deliver superior protection under extreme operating conditions including high RPM, elevated cylinder pressures, and reduced oil clearances often found in built or modified engines.

King's XP-Series bearings feature the brand's advanced pMaxKote polymer overlay, a proprietary dry-film coating applied to the bearing surface. This coating provides exceptional break-in protection, compensates for minor surface irregularities, and reduces friction — all critical factors in performance and racing applications where engine longevity and reliability are paramount.

Key Features:

• XP-Series Xtreme Performance design for high-load, high-RPM applications
• pMaxKote polymer overlay for enhanced break-in and friction reduction
• Tri-metal construction: steel backing, copper-lead or aluminum intermediate layer, and performance overlay
• Precision-manufactured to tight tolerances for consistent oil clearance
• Chamfered edges to accommodate large-radius crankshaft fillets
• High-eccentricity profile for optimal oil film distribution
• Direct OEM-replacement dimensions with performance-grade materials

King Engine Bearings are manufactured in Israel and are OEM suppliers to numerous global automakers, making the CR4099XP a trusted choice for engine builders seeking a direct-fit connecting rod bearing with race-proven performance characteristics.
