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
Excellent product
The 4p crankshaft bolt is a solid piece of hardware. I like being able to reuse it.
Looks strong and fits a socket so much better than a factory crank bolt
Nice 👍
