King Engine Bearings MB7092XP025 Main Bearing Set for Nissan - RB26DETT

The King Engine Bearings MB7092XP025 is a high-performance main bearing set specifically designed for the Nissan RB26DETT 24-valve engine. This XP Series bearing set features pMax Black tri-metal construction that delivers exceptional durability and load capacity for demanding racing applications.

Advanced pMax Black Technology:

The XP Series utilizes pMax Black, a unique tri-metal structure 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 layers. The 0.0005-inch metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue.

Key Performance Features:

• 15-30% Greater Load Capacity: Engineered to handle extreme performance loads for extended periods, ideal for forged steel aftermarket crankshafts
• Bulls Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001 inch for precise fitment
• Half-Grooved Main Design: Mains are 1/2 grooved for uncompromised lower shell load capacity
• Enlarged Chamfered Oil Holes: Improved oiling characteristics for better lubrication under high RPM conditions
• Medium Eccentricity: Optimizes load distribution and enhances oil delivery
• Narrowed Design: Accommodates large-radius crankshafts commonly found in performance builds

Racing Applications:

Designed for high-load, long-duration racing applications including circuit racing, drag racing, and other motorsports that utilize steel crankshafts. The XP Series is specifically engineered to withstand the highest loads and RPMs generated by today's top competition engines.

Oversized Specification:

This MB7092XP025 set features 0.25mm (0.010 inch) oversize dimensions for rebuilds requiring journal machining or increased clearance specifications.
