What does 'Standard X' size mean for these bearings?

The 'Standard X' designation indicates the size of the bearing. This is a standard size, but the 'X' suffix often denotes a specific manufacturing tolerance or slight variation within the standard range, ensuring precise clearance for your crankshaft.

Are these bearings suitable for daily driving or only racing?

While part of King's Alecular racing line and designed for high-load conditions, these bearings can also be beneficial for daily drivers seeking improved durability and oil control, especially in modified engines or vehicles used for towing or heavy-duty applications.

About this part

Product Details

This is a King Engine Bearings Performance Main Bearing Set, sized Standard X. This set includes the main bearings you need to rebuild or refresh the bottom end of your engine. These bearings are part of King's Alecular racing line, designed for performance applications where durability and consistent oil clearance are critical.

The Alecular racing line uses a unique overlay material that's engineered for high-load conditions, helping to prevent bearing failure under stress. They are built with a special micro-babbitt overlay that provides excellent conformability and embeddability, which is important for maintaining proper oil film thickness. This helps protect your crankshaft journals, especially in performance builds where engine speeds and loads can be higher than stock.

This set fits a wide range of Ford V8 4.6L DOHC and SOHC 24V engines, including popular models like the Ford Mustang, F-150, and Expedition. When installing, always ensure your crankshaft journals are clean and within specified tolerances for optimal performance and longevity.
