Lightened crank pulley from Raptor6767 aka Rene Didzor. Literally arrived last week from Croatia after 12 days. As I was planning on replacing thr Aux belt+ tensioner anyways I thought I might aswell upgrade the crank pulley also. My cheap impact gun wasn't strong enough to remove the crank pulley bolt so I ended up leaving the lightened pulley off. I paid £145 delivered and I was really looking forward to freeing up some revs and reducing parasitic losses caused by the AC. Let my loss be your gain. £130 delivered, also have it listed on ebay for £130 + £5 p&p
