The King Engine Bearings CS6603SI is a camshaft bearing set engineered for Ford's 4.6L and 5.4L 2-valve overhead camshaft (OHC) modular V8 engines. Designed as a precise OEM-replacement camshaft bearing, this set supports proper camshaft positioning, oil film retention, and rotational stability during engine operation.

King Engine Bearings has specialized exclusively in engine bearings since 1960, and the SI-Series designation indicates a silicon-aluminum bi-metal bearing material optimized for standard OE-replacement applications. The silicon-aluminum alloy construction provides excellent conformability, corrosion resistance, and fatigue strength suited to the demands of Ford's modular overhead cam architecture.

Key Features:

• Designed for Ford 4.6L and 5.4L 2-valve OHC modular V8 engines
• SI-Series silicon-aluminum bi-metal construction for OE-grade performance
• Standard (STD) size for use with unmachined, factory-specification camshaft journals
• Engineered to maintain precise oil clearances for proper lubrication and reduced wear
• Manufactured to rigorous quality control standards from concept to final product
• Full camshaft bearing set included — covers all journal positions
