Product Description

The King CR6640XP XP Series Connecting Rod Bearings are engineered for high-load, high-RPM performance applications in BMW inline-6 engines including the M20, M50, M52, and M54 platforms.

Ideal for engines using forged crankshafts or producing increased power, the CR6640XP set includes six precision-matched pairs to ensure reliable crankshaft support and long-term durability. Always verify engine code and journal size before installation.
