King Engine Bearings CR4604XPC.026 Performance Coated Connecting Rod Bearing Set

The King Engine Bearings CR4604XPC.026 is a premium XPC Series connecting rod bearing set designed for Ford 2.0L/2.3L Duratec and Mazda L3-VDT MZR DISI Turbo engines. This set includes 4 pairs of bearings with a .026mm (0.001 inch) oversize dimension.

XPC Series Advanced Technology:

The XPC Series features King's proprietary pMaxKote nano-composite polymer coating applied over the pMaxBlack overlay at the factory, enhancing wear resistance without changing the bearing's original precision wall thickness. This ceramic nano-composite coating functions as a fourth layer to enhance wear resistance. The pMaxKote has proven to protect bearings during metal-to-metal contact and from the erosive effects of cavitation.

Key Features:

• pMaxBlack overlay with 5% copper content and nano-scaled hardening process for superior strength
• Intermediate layer with 4.5% tin content, 22% harder (115 HV) with 17,000 psi load capacity
• Tri-metal structure provides 17% greater fatigue resistance
• SecureBond micro-etch surface preparation strengthens structural integrity and reduces delamination risk
• Excellent wear and cavitation resistance while protecting bearing surfaces during oil starvation and minimum oil film thickness
• No effect on oil clearance despite coating

Ideal for circle track, drag racing, off-shore, and other applications that utilize steel crankshafts. Developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.
