            Can’t go wrong with ARP

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

            Worked well. delivered as advertised

            the bolt worked well, much better steel than the one that came with my underdrive pullys.

            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

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

            Great Upgrade, High Quality

            I installed this bolt when I upgraded to the Steeda Underdrive pulleys and I would definitely recommend this product especially when changing the balancer. Includes thread lubricant to ensure proper torque and is of superior quality over the OEM bolt. As noted in other reviews it requires a 18mm 12 point socket and is great because the 12 point head is preferred on a bolt in a high torque app like this. An installation note is if you have a manual put the trans in 5th gear first and then use a breaker bar to remove the old bolt. Thanks again AM great product and service!.

            Great product

            I needed a balancer bolt that does not need to be replaced every time it is removed. Great product, perfect fit and comes with the required thread lubricant. Requires an 18mm 12-point socket for installation. Thanks AM.

            When installing my underdrive pulleys, I replaced the factory torque to yield Balancer bolt with a much stronger and easier to install ARP Balancer bolt.
