Construction & Design

The XP Series main bearings are constructed from a tri-metal copper-based alloy that balances strength, durability, and flexibility. This material composition allows the bearings to endure high loads and resist fatigue while maintaining excellent conformability to the crankshaft journals. The proprietary pMax black coating enhances load capacity and reduces friction, contributing to improved engine efficiency and extended service life.

King’s Radialock design ensures the bearings maintain optimal crush height, which is critical for proper oil film formation and bearing retention. This precision engineering minimizes the risk of bearing movement or failure under extreme operating conditions, making these bearings suitable for both high-performance and daily-driven engines.
