King CR8005XPSTDX XP Series Tri-Metal Connecting Rod Bearing Set for Ford 377

The King Engine Bearings CR8005XP STDX is a high-performance connecting rod bearing set engineered for Ford 377 applications running forged steel aftermarket crankshafts under extreme load conditions. Part of King's renowned XP Series, these bearings deliver advanced metallurgical and geometric technologies designed to survive the punishing demands of high-output, long-duration racing environments.

At the core of the XP Series is pMax Black, King's proprietary tri-metal overlay that is 24% harder than conventional tri-metal race bearings. This enhanced copper-lead construction includes a nickel barrier and SecureBond adhesion process for superior stability between the top and intermediate layers, dramatically reducing the risk of delamination under sustained high-load operation.

Key Features:

• pMax Black Tri-Metal Overlay: 0.0005" metallurgically hardened performance overlay resists surface fatigue and withstands greater loads than standard race bearings
• 15%–30% Greater Load Capacity compared to traditional connecting rod bearings
• Bull's Eye Tolerance: Industry-leading wall tolerances with all shells matched to within 0.0001" for precise, consistent fitment
• SecureBond Adhesion Process: Ensures superior bonding between the top and intermediate layers for long-term stability
• Increased Bearing Height: Improves bearing-to-bore contact, enhances heat transfer, and reduces spin potential at high RPM
• Medium Eccentricity: Optimizes load distribution and promotes consistent oiling across the bearing surface
• Narrowed Design: Compatible with large-radius crankshafts commonly found in high-performance builds
• Dowel Hole Options: Available with or without dowel holes to suit a variety of connecting rod configurations
• STDX Size: Standard clearance with extra-width shell for improved stability and load handling

Construction: Enhanced tri-metal copper-lead construction with nickel barrier and SecureBond adhesion layer for maximum durability in high-stress applications.

Ideal Applications:

• Circle track racing
• Off-road high-performance engines
• Offshore marine racing
• Any high-load, long-duration application using forged steel crankshafts

King Engine Bearings offers the industry's widest selection of sizes and clearance options, and the CR8005XP STDX is purpose-built for builders who demand uncompromising precision and performance in their Ford 377 builds.
