We recommend the Clevite H-Series Main bearings for all Engines over 500 HP, any type of Power Adder application and any engine that will see High RPM often. We use these bearings in nearly every engine we build. A must if you are using a Forged Crankshaft. Oversize Bearings are available for Crankshafts that have been cut down. Please select the size you need from the drop down menu.
