        Will this pulley work with my procharger? On my 05 mustang GT 4.6L 3V?

        do any bolts come with this? Install bolt, or are they available for 2006 4.6 3V ?

        • The SR Performance Harmonic Balancer will reuse the factory bolts. You will have to purchase the bolts separately if you need to replace them.

            New balancer for the supercharged 4.6

            Very good looking damper. Easy to install with plenty of adjustability. Appears to be durable. With the SFI rating it’s acceptable at the track!

            The rubber on my harmonic balancer was giving out fast and I knew I had to buy another one asap. And once again American Muscle has came in at the right time with a high performance balancer that is guaranteed to last a long tine. No matter how much I drive or race I feel satisfied knowing the balancer won't fail on me.
