King CR4542XPC XPC Racing Conrod Bearings for Honda K-Series Engines

The King Engine Bearings CR4542XPC Honda K-Series Connecting Rod Bearing Set is engineered for high-performance and competition Honda K-Series engine builds where increased bearing strength, consistent oil clearance and dependable protection under extreme loads are essential.

Designed for compatible Honda K20, K23 and K24 engines, these premium King XPC racing conrod bearings are particularly suited to tuned road cars, track cars, race engines, turbocharged Honda builds and high-RPM naturally aspirated K-Series applications.

Unlike standard replacement engine bearings, King’s XPC Series has been developed specifically for demanding motorsport and performance applications.

pMaxBlack™ Racing Overlay

King’s proprietary pMaxBlack™ overlay uses an advanced hardening process designed to increase bearing load capacity while maintaining the characteristics required for high-performance engines.

This makes the CR4542XPC particularly well suited to engines experiencing increased cylinder pressures and higher bearing loads caused by:

• Turbocharging
• Supercharging
• High-compression builds
• Increased RPM
• Performance camshafts
• Motorsport use
• Track driving
• Drag racing
• Modified K-Series engines

pMaxKote™ Polymer Coating

The CR4542XPC receives King’s factory-applied pMaxKote™ polymer coating, developed to improve resistance to wear and seizure.

The coating is engineered so that it does not significantly alter the original bearing wall thickness, helping engine builders maintain accurate bearing clearances.

This additional protection is especially beneficial during cold starts, high-load operation and other conditions where the engine’s oil film may be placed under extreme stress.

Installation Recommendation

Performance engine bearings should be installed by an experienced engine builder.

Before final assembly, always verify:

• Crankshaft journal diameter
• Crankshaft condition
• Connecting rod housing bore
• Bearing oil clearance
• Bearing crush
• Crankshaft surface finish
• Required bearing size
• Engine code
• Oil system condition

Do not assume that standard-size bearings are correct simply because the crankshaft is believed to be standard.

Bearing clearance should be measured accurately during assembly.
