Replace that old and crusty crank pulley bolt with a more durable ARP replacement.  There is nothing worse than putting your hard earned money into building a masterpiece engine and having to top it off with a crummy looking oxidized OEM bolt.

This is a direct replacement for the OEM bolt and can be torqued and reused as many times as you like.  This bolt has a much higher clamping load with its drastically increase yield and tensile strength.  ARP and 4 Piston are proudly engraved on the head of the bolt.

Fits K20, K24, K24Z, K20C1, F20C, F22C
