Do I need the ati balancer for a 8 rib procharger d-1? do I need to pin these? These seem to be alot less expensive. $150

 

Yes, the ATI Performance Products balancer is the only balancer that the ProCharger bolt on crank pulley will seat against and is also the only balancer that the ProCharger bolt on crank pulley will bolt to.
Here is the one we use most often.

Thanks I thought I might have found a deal on one.

 

Not a problem, I have not found anything else that works and the ATI balancer is the best balancer on the market, which is a plus for your engine's well being. Bob
