King Engine Bearings CR 222GPC0.25 Race Connecting Rod Bearing Set BMW N55B30A 0.25mm Oversize

The King Engine Bearings CR 222GPC0.25 is a high-performance racing connecting rod bearing set engineered as a sputter replacement for the BMW N55B30A engine. This set includes 4 bearing shells (2 pairs) ground to a 0.25mm oversize specification, making it ideal for engines with journals that have been machined undersized.

These bearings feature King's advanced GPC (Race Polymer-SilveRace) tri-metal construction — a premium silver-based material capable of withstanding up to 17,000 PSI, far exceeding conventional race bearing materials that peak near 11,000 PSI. The GPC construction consists of an intermediate lead-bronze layer over a steel backing, topped with a silver overlay containing solid lubricant particles for extreme-load protection.

Key Features:

• GPC Tri-Metal Construction: Silver-based composite with polymer coating for superior load capacity up to 17,000 PSI
• Polymer Coating: Factory-applied nano-composite polymer coating creates a thermal barrier between connecting rods and crankshaft, protecting against oil starvation and metal-to-metal contact
• 0.25mm Oversize: Precision-ground for use with reground or undersized crankshaft journals
• Radialock™ Technology: Optimized crush height and eccentricity values derived from elasto-hydrodynamic analysis for a precise, stable fit
• Sputter Replacement Design: Direct replacement for factory sputter-type bearings found in high-performance BMW engines
• Includes: 4 bearing shells (2 pairs) — a complete connecting rod bearing set

King Engine Bearings are manufactured to strict tolerances using in-house design and production processes, making them a trusted choice for performance engine builds, motorsport applications, and diesel performance. The CR 222GPC0.25 is the ideal solution for BMW N55B30A engine rebuilds requiring an undersized bearing to restore proper oil clearances.
