Main Stud Girdle

Ford ’ s factory two-bolt main cap assembly is fine for mildly built 429 / 460 engines , but if you ’ re shooting for big power , you need this Main Stud Girdle . The girdle ties the main bearing caps and bulkheads together to sufficiently stiffen the lower-end of the block and provide proper crankshaft support . Each girdle is made from black oxide-coated tool steel , and includes ARP main cap bolts and a provision for an oil pump pickup tube hold down .
