King Engine Bearings CR6640XPCSTDX Connecting Rod Bearing Set BMW M20 M50 pMaxKote

The King Engine Bearings CR6640XPC STDX is a standard-size connecting rod bearing set engineered for BMW M20 and M50 inline-six engines displacing 2.0L, 2.5L, and 2.7L. Designed as a direct replacement for worn or damaged OEM rod bearings, this set delivers enhanced performance and durability over stock bearings—making it equally suitable for street rebuilds and performance applications.

These bearings feature King's proprietary pMaxKote polymer coating technology, part of their premium racing line. pMaxKote is a advanced PTFE-based polymer coating applied to the bearing overlay that reduces friction, improves oil film retention, and provides superior protection during cold starts and oil starvation events. The coating also enhances compatibility with modern synthetic lubricants and helps extend bearing service life under high-load conditions.

Key Features:

• pMaxKote Polymer Coating – Proprietary friction-reducing PTFE overlay for improved wear resistance and cold-start protection
• Standard (STD) Size – Direct-fit replacement for unmodified OEM journal diameters; no machining required when journals are within spec
• Racing Line Quality – Manufactured to tight tolerances for consistent oil clearance and reliable performance
• Tri-Metal Construction – King's proven layered bearing design with a copper-lead or aluminum alloy intermediate layer for strength and conformability
• Compatible Engines – BMW M20 and M50 series inline-six, covering 2.0L, 2.5L, and 2.7L displacements
• Full Set – Includes all connecting rod bearings required for a complete engine rebuild
