Have a lower crank pulley kit from Paramount Performance(Viezu) from the UK. Can't use because they say the pulley needs to be balanced and can't find a balanced. It'll fit 5.0 XJ, XF, F Type probably XK. Comes with pulley, idler and belt never installed. Paid 995£, they wont take return cause it greater than 30 days. They want me to ship them both the stock pulley and the one they sold so they can balance it. No where on their site did it say the new one would need balancing. PM me if interested.
