King Engine Bearings CR808XPNDC010 XP-Series Polymer-Coated Connecting Rod Bearing Set Big Block Chevy 369-502 Gen IV/V/VI 0.010 Under

The King Engine Bearings CR808XPNDC010 is an XP-Series connecting rod bearing set engineered for Chevrolet Big Block 369-502 cubic inch engines (Generation IV, V, and VI). This set features a 0.010-inch undersize specification and is finished with King's proprietary pMaxKote nano-composite polymer coating, making it an ideal choice for high-performance street and racing builds.

The pMaxKote coating is applied at the King factory over the pMaxBlack overlay as part of the bearing manufacturing process. It incorporates ceramic nano-composite particles that function as a fourth protective layer, enhancing wear resistance and protecting against metal-to-metal contact and the erosive effects of cavitation — without adding any thickness to the bearing's original precision wall dimension.

Key Features:

• pMaxKote Polymer Coating: Factory-applied nano-composite polymer coating for superior seizure and wear resistance, engineered to protect during oil starvation and marginal lubrication conditions
• XP-Series Design: Narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-RPM applications
• pMaxBlack Overlay: Features 5% copper content and a proprietary nano-scaled hardening process, delivering significantly stronger fatigue resistance than conventional overlays
• Bull's Eye Wall Tolerances: Advanced quality control maintains rod bearing wall thickness to an exceptionally tight ±0.0001 inch — far exceeding industry standards
• 0.010-Inch Undersize: Designed for use with crankshafts ground 0.010 inches under standard journal diameter
• Application: Chevrolet Big Block (BBC) 369–502 cubic inch engines, Generation IV, V, and VI

King Engine Bearings focuses exclusively on engine bearings, bringing race-proven technology to both performance and street applications. The DC designation confirms these bearings are purpose-built for polymer coating from the earliest stages of the manufacturing process, ensuring optimal coating adhesion and durability.
