King Engine Bearings CR8032XPNCSTDX XPC Series Connecting Rod Bearing Set

The King Engine Bearings CR8032XPNCSTDX is a high-performance XPC series connecting rod bearing set engineered for Chrysler 345, 370 16V HEMI engines (5.7L, 6.1L, and 6.4L). This race-grade bearing set features King's advanced pMaxKote nano-composite polymer coating applied over the revolutionary pMaxBlack tri-metal structure, delivering superior protection for demanding performance applications.

Advanced pMaxKote Technology: The factory-applied pMaxKote coating provides a fourth protective layer without adding any wall thickness, ensuring precise oil clearances remain unchanged. This nano-composite polymer coating offers superior seizure resistance, exceptional wear protection during metal-to-metal contact, enhanced cavitation resistance, and critical protection against oil starvation conditions. The coating contains ceramic nano-composite particles that dramatically improve bearing durability under extreme loads.

XP Series Tri-Metal Construction: Built on King's proven XP series foundation, these bearings feature the pMaxBlack overlay—a surface-hardened lead-tin-copper layer that is 24% harder than conventional tri-metal race bearings. The pMaxBlack intermediate layer contains 4.5% tin content, achieving a load capacity of 17,000 psi with a hardness of 115 HV. The overlay incorporates 5% copper content for superior fatigue strength, capable of handling loads up to 10,200 psi.

Narrowed Design with X-Factor Clearance: This bearing set features a narrowed design optimized for high-performance applications with aftermarket forged steel crankshafts. The STDX designation indicates standard size with X-factor clearance specifications for precise fitment and optimal oil film thickness in race and high-load street applications.

Each bearing is manufactured to King's exacting precision standards and designed for extended service life under extreme performance conditions including road racing, drag racing, and boosted applications.
