This is the longer bolt used to install the new crankshaft pulley on your R50 R52 R53 MINI Cooper and Cooper S. This is the same bolt and washer that comes with the new ATI damper. With this longer bolt it will allow you to press the new crankshaft pulley on about half way. You can stack additional washers on it to use it to press the pulley on further, or after it is on about half way use the stock bolt to press it on the rest of the way.
Comes as one long bolt with washer that is threaded to match W10 and W10 MINI engine crankshaft threads.
