King Performance Conrod Shells for BMW N55 and S55 - Standard Size - Part No: CR222SV STD

Looking for a bottom-end refresh or a preventative maintenance upgrade on your turbocharged BMW straight-six. These King SV-Series standard-dimension con-rod shells deliver the strength, consistency and oil film stability demanded by fast-road and trackday use. Built on a copper-based, lead-free construction with a sputtered overlay, they are engineered to handle high cylinder pressures while maintaining smooth crank journal rotation and dependable wear characteristics.

Ideal for BMW enthusiasts protecting their investment or engine builders chasing reliable power, this OE-size shell set is a direct-fit solution for N55 and S55 applications. Manufactured by King for precise geometry and consistent clearances, they help safeguard the crank pins, reduce frictional losses and support long service life under sustained load.

Why this upgrade works

• Sputtered overlay on a copper-based bearing for excellent fatigue strength under high load
• Lead-free design with proven wear resistance and stable oil film retention
• Standard size for straightforward installation where OE journal dimensions are retained
• Supports smooth, reliable crank rotation during hard acceleration and heat cycles
• King quality and dimensional accuracy for confidence in performance builds

We use these shells on our own builds and customer engines, and feedback has been consistently positive for both road and circuit use. A smart choice for a bottom-end refresh, engine rebuild or preventative bearing service on BMW N55 and S55 powerplants.
