Shipping calculated at checkout.
There are 1 units left in stock.
With ARP no longer reliably stocking 7.3 IDI head stud kits, we have sourced a new manufacturer to support our 7.3 IDIs with a superior, American made head stud kit. Using 8740 chromemoly steel, these studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi (greater than ARP's 190k rating) comes with 4oz Amsoil assembly lube bottle.
*UPDATE 6/20/22 with increased demand for these stud kits we are able to increase our purchase lot sizes and offer studs cheaper than before!
Replaces ARP 250-4204
