King Engine Bearings MB5232XP05 XP Series Main Bearing Set Nissan - CA16DET CA18DET CA20ET

The King Engine Bearings MB5232XP05 is a high-performance main bearing set designed specifically for Nissan CA16DET, CA18DET, and CA20ET engines. This XP Series bearing set features King's advanced pMax Black tri-metal construction, engineered to withstand extreme loads in racing and high-performance applications using forged steel aftermarket crankshafts.

pMax Black Tri-Metal Technology:

• 24% harder than conventional tri-metal race bearings
• Enhanced copper-lead construction with nickel barrier layer
• 0.0005" metallurgically hardened performance overlay resists surface fatigue
• SecureBond adhesion process ensures superior stability between layers
• 15-30% greater load capacity than traditional bearings

Performance Features:

• Bull's Eye Tolerance: Industry-leading wall tolerances with all shells matched to 0.0001"
• Half-Grooved Design: Mains are 1/2 grooved for uncompromised lower shell load capacity
• Medium Eccentricity: Optimizes load distribution and improves oil flow
• Enhanced Oiling: Enlarged, chamfered oil holes in main bearings
• Narrowed Profile: Accommodates large-radius crankshafts

Ideal for high-load, long-duration racing applications including circle track, off-road, and other motorsports that demand maximum durability and performance. These bearings are specifically engineered for engines producing high loads for extended periods at elevated RPM.
