The ARP 250-4202 Head Studs are a must-have upgrade for your 03-07 Ford 6.0L Powerstroke. These extra heavy duty studs are rated at 220,000 psi tensile strength and provide the clamping force required to keep your 6.0L Powerstroke’s cylinder heads from lifting due to higher combustion pressures.

Manufactured in ARP’s Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treating to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers, with a black oxide finish for extra durability. ARP also offers the Inner Row Head Bolts as an add-on to compliment this head stud kit (sold separately, see related items below).


  • 220,000 PSI Tensile Strength
  • Replaces Factory Head Bolts
  • Black Oxide Finish
Note: ARP is aware of forum postings providing incorrect torque values. Please follow the included installation instructions for proper torque specifications and tightening sequence.

Blew head gasket after installing Sct tuner and deleting egr cooler, new oil cooler and turbo clean on my 04 6.0L ... Had coolant puking from degas cap "over flow" ..... Took it into dealer told him the work I've had done to it the week prior too and he told me without even looking at the truck 99% sure it was going to be failed head gasket caused by fords shity tty head bolts.. I ordered these arp studs that day and they shipped and were at my house the very next evening! Very impressed!!! The 5 star rating right now is just from shipping fast and customer service taking studs to dealer today to get my expensive investment back onto the road!
