DESCENDANT Crank Bolt

DESCENDANT / WORLD-Racing ARP 2AZFE Crank Bolts feature a 12 point head that provide much more surface to apply the torque. Three times stronger than the OEM part. WORLD Racing uses these on their race cars. Put on a 19mm 12 point socket and you're in business to crank it down. For those that degree in your cams, this offers a much more precise way of attaching your breaker bar to the crank bolt...no slop that is offered with the stocker 6 point hex head or worse yet, the 1/2" square peg hole in the head of the stocker bolt.
