King Engine Bearings CR4002AM1.5 AM-Series Connecting Rod Bearing Set Mazda 1.6 B6 +1.5mm Oversize

The King Engine Bearings CR4002AM1.5 is an AM-Series connecting rod bearing set designed for the Mazda 1.6L B6 four-cylinder engine. This is the +1.5mm oversize variant, intended for engines with reground or worn crankshaft rod journals that require an oversize bearing for proper clearance restoration. The set includes 4 pairs of bi-metal half-shell bearings.

King's AM-Series bearings utilize an Alecular aluminum alloy material — an alloy of aluminum, tin, and copper applied over a high-strength steel backing. This standard aluminum-based material is equivalent to SAE-783 and is well-suited for low- to medium-load passenger car engines, making it an ideal OE-replacement choice for street and marine applications.

Key Features:

• AM-Series bi-metal construction — Alecular aluminum alloy on high-strength steel backing
• +1.5mm oversize — designed for reground crankshaft rod journals
• Superior embeddability for greater macro-particle tolerance, protecting crank journals from scratching
• Precision tolerance control up to ±0.0001 inches for accurate oil film clearance
• Lead-free construction — environmentally friendly and user-safe
• Replaces OEM part numbers: B6Y0-11-SF0, B6Y0-11-SE0, B6Y0-11-SFX, B6Y1-11-SE0, B6Y2-11-SE0, OBPY3-11-SE0, OK2YA-11-SE0
