King Engine Bearings CR4042XP025 Performance Connecting Rod Bearing Set

The King Engine Bearings CR4042XP025 is a high-performance connecting rod bearing set engineered specifically for BMW M40, M42, M43, and M44 engines (1.6L, 1.8L, 1.9L). Part of King's acclaimed XP Series, these bearings feature pMax Black tri-metal construction that delivers 24% greater hardness than conventional tri-metal race bearings, making them ideal for high-load racing applications with forged steel aftermarket crankshafts.

Key Features:

• pMax Black Tri-Metal Construction: Enhanced copper-lead structure with nickel barrier and SecureBond adhesion process for superior layer stability
• Extreme Load Capacity: 15-30% greater load capacity than traditional bearings for extended high-performance use
• Hardened Performance Overlay: 0.0005" metallurgically enhanced overlay resists surface fatigue and withstands extreme loads
• Bull's Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001" for precise fitment
• Increased Bearing Height: Improves bearing-to-bore contact and heat transfer while reducing spin potential at high RPM
• Medium Eccentricity Design: Optimizes load distribution and improves oiling efficiency
• Narrowed Profile: Specifically designed for large-radius crankshafts

This 0.25mm oversize bearing set is ideal for circle track racing, off-road, offshore, and other high-load, long-duration applications that demand maximum durability from forged steel crankshafts. King's proprietary SecureBond adhesion process ensures exceptional stability between bearing layers, while the half-grooved main design maintains uncompromised lower shell load capacity.

Application: BMW M40, M42, M43, M44 engines (1.6L-1.9L)

Size: 0.25mm oversize
