ARP 250-4201 Head Stud Kit | 1994–2003 7.3L Powerstroke | ARP2000
Protect your 7.3 Powerstroke from blown head gaskets with the industry-leading ARP 250-4201 Head Stud Kit. Designed specifically for the Ford 7.3L Powerstroke diesel (1994–2003), these heavy-duty head studs replace the factory head bolts with dramatically superior clamping force, keeping cylinder heads securely seated under high boost, heavy towing, or high-performance conditions.
Manufactured in ARP’s Santa Paula, California facility from proprietary ARP 2000 alloy, each stud is heat-treated and features threads rolled after heat treatment for exceptional fatigue strength. With a tensile strength of 220,000 psi, these studs deliver the clamping force needed to prevent head lift and gasket failure in truck and RV applications.
The complete Pro Series kit includes 36 ARP 2000 head studs, 36 high-strength 12-point nuts, and 36 parallel-ground hardened washers for even load distribution and accurate torque readings. Studs are centerless ground for perfect concentricity and broached on the ends (5mm Allen) for easy installation and removal—even in tight engine bays. A durable black oxide finish provides excellent corrosion resistance.
Trusted by professional diesel engine builders, ARP head studs are the gold standard for reliability on stock, modified, and high-mileage 7.3L Powerstrokes.

As with all purchases I have had with Full Force, the quality is outstanding. Full Force is my go to company for my OBS 7.3. They have great prices, very knowledgeable, friendly and helpful not to mention delivery is quick. If Full Force sells it I would recommend it.
