King Engine Bearings CR4046XPC0.25 pMaxKote Connecting Rod Bearing Set Oversize - 0.25mm

The King Engine Bearings CR4046XPC0.25 is a +0.25mm oversize pMaxKote performance connecting rod bearing set engineered for Honda B20B4, B20Z2, D16 Series, ZC, and 16V engines. Designed for engine rebuilds where the crankshaft journals have been machined undersize, this set restores proper clearances while delivering race-proven bearing technology.

Built on King's tri-metal copper-based construction, these rod bearings feature a steel backing, copper-lead intermediate layer, and a nickel barrier plate topped with a lead/tin/copper Babbitt overlay. This proven architecture delivers outstanding load capacity, fatigue resistance, and durability under high-stress operating conditions.

pMaxKote Polymer Coating:

• Factory-applied nano-composite polymer coating added directly over the XP tri-metal substrate
• Provides superior seizure resistance during cold starts and oil starvation events
• Enhanced cavitation and wear resistance for extended bearing life
• Increased load-carrying capacity without adding additional wall thickness

King Precision Manufacturing Technologies:

• Bull's Eye Tolerance™ — wall thickness maintained to an industry-leading ±0.0001 in. tolerance
• Radialock™ — optimized crush height geometry ensures secure bearing retention and consistent bore contact
• Narrowed profile on the crank cheek side for improved heat transfer and reduced spin potential at high RPM

The CR4046XPC0.25 is part of King's Racing (XPC) line, purpose-built for performance and competition applications including forced induction, high-compression, and high-revving engine builds. Sold as a complete connecting rod bearing set.
