Show original supplier description
The King AM-Series Main Bearings MB5568AM are designed as a direct replacement for various Honda and Acura engines. These main bearings are constructed with a bi-metal (aluminum base) and alecular silicon alloy, offering superior embeddability to minimize scratching on crank journals and reduce wear on Babbitt overlays. These bearings are recommended for street or marine applications and feature tolerance control to within plus or minus .0001. They are lead-free, making them an environmentally friendly and user-safe option. The set includes 5 bearings and is a standard size for crankshafts. Fitment includes a wide range of Honda and Acura vehicles, such as the Acura Integra (1986-1989, 1.6L), Acura CL (1998-1999, 2.3L), Acura ILX (2013-2015, 2.4L), and various Honda Accord and Civic models with specific engine displacements from 1.6L to 2.3L.
