King Engine Bearings CR4033XP025 Performance Connecting Rod Bearing Set

The King Engine Bearings CR4033XP025 is a high-performance connecting rod bearing set designed for Honda F20C, F22C, B20, and H22 16V engines. Part of King Racing's XP Series, these bearings feature advanced metallurgical and geometric technologies engineered to withstand extreme loads in demanding racing applications.

pMax Black Tri-Metal Construction:

The XP Series utilizes pMax Black technology, a unique tri-metal structure that is 24% harder than conventional tri-metal race bearings. This enhanced copper-lead construction features a nickel barrier and SecureBond adhesion process for superior stability between layers. The 0.0005" metallurgically enhanced performance overlay provides exceptional resistance to surface fatigue and wear under high-stress conditions.

Key Performance Features:

• Bull's Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001" for precise fitment
• 15-30% Greater Load Capacity: Engineered specifically for forged steel aftermarket crankshafts and extended high-load racing
• Increased Bearing Height: Improves bearing-to-bore contact and heat transfer while reducing spin potential at high RPM
• Medium Eccentricity: Optimizes load distribution and improves oil flow characteristics
• Narrowed Design: Accommodates large-radius crankshafts common in performance builds
• SecureBond Adhesion: Unique bonding process ensures superior layer stability under extreme conditions

Racing Applications:

Ideal for high-load, long-duration racing including circle track, off-road, endurance racing, and other motorsports applications using steel crankshafts. These bearings are engineered to handle the extreme loads and sustained high RPM conditions found in professional racing environments.

This is a standard size bearing set with +0.025" oversize available for precision engine building. The half-grooved main bearing design maintains uncompromised lower shell load capacity while ensuring adequate lubrication.
