King Engine Bearings CR410XPSTDX XP Series Tri-Metal Connecting Rod Bearing Set

The King Engine Bearings CR410XPSTDX is a XP Series high-performance connecting rod bearing set engineered for Ford and Lotus 1.5L and 1.6L OHV engines. Designed for serious performance and racing applications, these bearings feature King's advanced pMax Black tri-metal construction — a metallurgically enhanced overlay that is 24% harder than conventional tri-metal race bearings — delivering exceptional load capacity and fatigue resistance under extreme operating conditions.

The XP Series was developed specifically for performance applications utilizing forged steel aftermarket crankshafts that generate high loads over extended periods. Whether on the circle track, off-road course, or offshore circuit, these bearings are built to match the demands of today's most competitive race engine builds.

King XP Series Features:

• pMax Black Tri-Metal Construction: Enhanced copper-lead tri-metal structure with nickel barrier and SecureBond adhesion — 24% harder than conventional tri-metal race bearings
• SecureBond Adhesion Process: Provides superior stability between the top and intermediate layers for long-duration reliability
• 0.0005" Performance Overlay: Metallurgically enhanced and hardened overlay withstands greater loads and resists surface fatigue
• 15%–30% Greater Load Capacity: Outperforms traditional bearings in high-stress, high-RPM environments
• Bull's Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001" for precise fitment
• Increased Bearing Height: Improves bearing-to-bore contact and heat transfer while reducing spin potential at high RPM
• Medium Eccentricity: Enables optimum load distribution and improved oiling characteristics
• Narrowed Design: Compatible with large-radius crankshafts for modern performance applications
• Dowel Hole Options: Available with or without dowel holes to suit your specific application

Applications:

• High-load, long-duration racing including circle track, off-road, and offshore motorsports
