ATI. Simply the best. I went with a BB Chev bolt pattern on mine to open up pulley and drive options....this is a stocking part. You have a lot of choices , so I'd go to their web site and see what best fits your needs.
Haven't heard anything but good about ATI. If cost is a factor and you still want an SFI balancer, Pioneer is a good choice. I would avoid BHJ due to slippage issues.
