King Engine Bearings CR804XPNC XP-Series Tri-Metal Connecting Rod Bearing Set Ford 260/289/302 Windsor

The King Engine Bearings CR804XPNC is an XP-Series tri-metal connecting rod bearing set engineered for Ford small-block 260ci, 289ci, and 302ci (5.0L) Windsor engines. Designed for demanding race and high-performance street applications, this set combines King's proven pMaxBlack™ tri-metal construction with the advanced pMaxKote™ ceramic nano-composite polymer coating for maximum durability and protection.

pMaxKote™ Ceramic Nano-Composite Polymer Coating

The pMaxKote™ coating is applied at the King factory over the pMaxBlack™ overlay as an integral part of the manufacturing process. Its ceramic nano-composite particles function as a fourth bearing layer, significantly enhancing wear resistance, seizure resistance, and cavitation protection — all without altering the bearing's original precision wall thickness dimensions.

Key Features:

• XP-Series Tri-Metal Construction: pMaxBlack™ overlay with proprietary nano-scaled hardening process delivers superior load capacity and fatigue resistance
• pMaxKote™ Coating: Ceramic nano-composite polymer coating protects against wear, seizure, and cavitation during metal-to-metal contact events
• Narrowed Design: Bearing width is reduced compared to OE/stock versions to clear large-fillet crankshafts — no additional machining required
• Bull's Eye Tolerance™: Wall thickness maintained to an industry-leading ±0.0001" tolerance, eliminating the need to "fish" for correct clearance
• Race-Proven: Suitable for circle track, drag racing, offshore, and other high-load applications using steel crankshafts
• Standard Size: OEM journal diameter, for use in standard (uncut) crankshafts

King Engine Bearings has specialized exclusively in engine bearings since 1960, applying lessons learned on the racetrack to deliver precision components for both competition and high-performance street engines. The CR804XPNC is an ideal choice for builders rebuilding or upgrading Ford Windsor small-block engines where maximum bottom-end protection is required.
