HEAVY DUTY MAIN BEARING STUDS
Heat treated chrome moly main bearing studs (case studs) are necessary to prevent the cases from moving around under power in high output engines. These high strength studs help to prevent crankshaft damage.
Made from the same special chrome moly that we use in our cylinder studs. All threads are rolled after heat treat for maximum strength.
All sets come with special flanged nuts and instructions.
