Description

The Sealed Power 148M is a set of main bearings designed for high-performance applications. These bearings are constructed with an H14 Super Duty alloy and a best bronze alloy, and they do not have flash tin plating. They offer extreme fatigue resistance and strength, with an application-specific design for a perfect fit and correct operation. The silicon particles in the material help polish the crankshaft journal, reducing wear during operation. This product is an O.E.M. replacement and comes with a package quantity of 6.
