King Engine Bearings CR6697XP0.5 High Performance Connecting Rod Bearing Set for Nissan RB25DET RB26DETT

The King Engine Bearings CR6697XP0.5 is a high-performance connecting rod bearing set engineered specifically for Nissan RB25DET and RB26DETT engines. Part of King's advanced XP Series, these bearings feature pMax Black tri-metal technology that delivers 24% greater hardness than conventional tri-metal race bearings, making them ideal for demanding racing applications with forged steel aftermarket crankshafts.

Advanced XP Series Technology:

• pMax Black Tri-Metal Construction: Enhanced copper-lead tri-metal structure with nickel barrier and SecureBond adhesion process for superior layer stability
• 15-30% Greater Load Capacity: Engineered to withstand extreme performance loads for extended periods in high-stress racing environments
• Hardened Performance Overlay: 0.0005" metallurgically enhanced overlay resists surface fatigue and handles greater loads than standard bearings
• Half-Grooved Main Bearings: Uncompromised lower shell load capacity for optimal performance

Precision Engineering Features:

• Bull's Eye Tolerance: Industry-leading wall thickness tolerances with all shells matched to 0.0001" for consistent performance
• Increased Bearing Height: Improved bearing-to-bore contact enhances heat transfer and reduces spin potential at high RPM
• Optimized Oiling: Enlarged, chamfered oil holes in main bearings ensure proper lubrication under extreme conditions
• Medium Eccentricity Design: Enables optimum load distribution throughout the bearing surface
• Narrowed Profile: Compatible with large-radius crankshafts common in performance builds

Ideal Applications:

• High-load, long-duration racing including circle track, off-road, and endurance competitions
• Performance builds using forged steel aftermarket crankshafts
• Applications requiring sustained high RPM operation

This 0.5mm oversize bearing set is designed for engines that have been machined oversize, providing the precision fit required for race-winning performance. King's SecureBond adhesion process ensures superior stability between bearing layers, preventing delamination under extreme racing conditions.
