Extra Long Crankshaft Bolt

Why the factory would make deep threads on the crank and then install the front pulley with a nut that can only use half of them is a mystery. This bolt and it's special washers allow you to utilize twice as many threads and stop worrying about your nut coming loose. To make this part even better we have chosen to use a 1" hex, smaller and easier to find at your local tool shed.
