King Engine Bearings CR6877XPC STDX Connecting Rod Bearing Set with pMaxKote for BMW S54B32 3.2L

The King Engine Bearings CR6877XPC STDX is a performance connecting rod bearing set designed for the BMW S54B32 3.2L inline-six engine, part of King's XPC Racing Line. These bearings feature the advanced pMaxKote™ nano-composite polymer coating, applied over King's proprietary pMaxBlack™ tri-metal overlay at the factory during the manufacturing process — delivering race-level durability for high-performance and competition applications.

Key Features:

• pMaxKote™ Polymer Coating: A nano-composite polymer coating applied over the pMaxBlack™ overlay, enhancing wear and seizure resistance without adding any thickness to the bearing's precision wall dimension
• Ceramic Nano-Composite Particles: Function as a fourth protective layer, significantly improving load capacity and resistance to fatigue under extreme engine loads
• STDX Size: Measures 0.005" thinner than OEM standard (STD) specification — ideal for engine builders dialing in tighter oil clearances on performance builds
• XPC Racing Line: King's top-tier race-series bearing designed for high-output and competition engines, including forced induction and naturally aspirated builds
• Tri-Metal Construction: pMaxBlack™ base structure combines a unique tri-metal layered design with advanced surface processes to deliver superior load capacity
• Lead-Free Formulation: Environmentally responsible bearing material using alternative compounds to achieve optimal performance
• Factory Applied Coating: pMaxKote is applied during the bearing manufacturing process at the King factory — not an aftermarket treatment — ensuring consistent, precision coverage

The CR6877XPC STDX is engineered for builders seeking maximum protection and performance in the BMW S54B32 3.2L engine. King recommends these bearings for use with steel crankshafts and high-output applications including circuit racing builds. The STDX sizing designation allows builders to fine-tune oil film clearances beyond OEM spec for demanding race environments.
