High Tensile 7.3 IDI Head Stud Kit

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. These studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated for over 220,000 psi tensile strength, with the highest tensile rating of any 7.3 head stud kit on the market.

Replaces ARP 250-4204

-Tested up to 200 ft lbs and 60 psi of boost!
