This item snugs down onto the original exhaust nut and the tangs lock into the cooling fins on the cylinder helping to prevent the exhaust nut from loosening, while also offering additional cooling. These can also be used on V700, Ambassador, Eldorado, 1969 to 1972 V7 Special and 850GT with original exhaust nuts. Sold individually.
Note: These clamps exist to provide a locking mechanism for the original exhaust nuts that do not have a locking mechanism. They will not fit the aftermarket exhaust nuts that come equipped with a built-in locking ring.
