        Harmonic Balance Bolt Kit

        I have yet to install the Bolt and new Balancer because I'm unable to do it myself so I'm waiting on someone else to do it. But the reason I got this one is due to the good reviews.

        Can’t go wrong with ARP

        It’s an ARP bolt, works as it should and will outlast the car I’m sure.

        Works great

        Perfect fit. Much easier to torque with the 12 point socket rather than the six. Used with steeda under drive pullies and install was a breeze.

        Does not work with Aftermarket Balancers

        I bought this to go along with an innovators West balancer. The bolt was too short! Fyi

        ARP quality

        High quality bolt. Was a better stronger replacement for my damaged factory crank bolt. Used on my 97 cobra mustang.
