Perfect Circle MS2202H H-Series Main Bearing Set Ford Modular 4.6L 5.4L

The Perfect Circle MS2202H is a high-performance H-Series main bearing set designed for Ford Modular V8 engines. This set features half groove TM-77 tri-metal construction and includes 6 bearings, providing complete coverage for 4.6L and 5.4L Windsor iron block applications.

Key Features:

• Medium level of eccentricity, high crush, hardened steel back and thin overlay without flash plating for better seating
• Steel backings with carefully selected overlays, high crush factor, and enlarged chamfers for greater crank-fillet clearance
• Tri-Metal construction combines copper-lead alloy layer with steel backing and electroplated babbitt metal for optimal slipperiness and conformability
• Made in Atlantic, Iowa USA
• Fits engine codes 6, W, and X with cast iron blocks

Originally developed for NASCAR racing, these H-Series bearings are ideal for competition engines that run at medium-to-high RPM ranges. These bearings work best with crankshafts that have oversize fillets, making them an excellent choice for performance rebuilds and racing applications.
