What gear to run with cam

their tech support sometimes is a pos.....i asked the same question, same answer. After discussing with other people i found these cams have a cast core.....easy to see. Then you´re ok with the stock cast iron gear. If it´s a billet core (shiny, machined surface everywhere) then you should use a special gear. Mine (xr286hr) is working flawlessly with the stock intermediate shaft.
