aftermarket under drive pullys
i heard some bad stuff bout the lightened crank pully? i heard it can mess up your crank and unbalance it in the long run. can anyone back this up?
I would recommend staying with the stock harmonic balancer. On all the high horse power motors that I have seen and done with the lighten pulley they alwyas end up shatering the oil pump gear. then once we switched it back to the normal harmonic balancer thier is no more problem. Just my opinion.
