Description
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 Powerstrokes cylinder heads from lifting due to higher combustion pressures.
Manufactured in ARPs 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).

Well worth it
2003-F250-6.0
Location: USA
I've used ARP products a lot over the years, and on the 6.0 they're especially good. Top-quality steel alloy, made in the US, and they take and hold torque with the lube. I torqued to 230lbf (between ARP's old and new advice) at night, then confirmed all of them in the morning, and they held as expected. Given the learnings over time I'd make sure it look up ARP's latest advice of course.
The install is tricky with the cab on, but there are lots of good articles describing tricks like zip-ties to hold them up in certain places. Through taking it slow with a custom gantry crane I was able to get really good results.
Now ~4000 miles in there are no signs of problems on new factory replacement blue gaskets on a 2003 (early build) 6.0, and it started up the first time. The original gaskets were stamped with a 2003 date code and lasted 110k, and I hope with ARP studs the new gaskets should last forever. Factory tune... for now. Thanks XDP!
very fast shipping

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!

Is this everything I will need?
View Staff Answer
Answer
Everything needed for the studs are included. (We recommend taking a look at our XDP Powerstroke Solution with Ford Factory Head Gaskets for t everything needed to fix all the major problems with the 6.0L Powerstroke. No more stretched bolts, blown head gaskets, white smoke from the EGR cooler, or defective EGR Valves. – Click Here)
Do I have to pull the cab to install the studs?
View Staff Answer
Answer
Some recommend having the cab pulled for ease of installation, but it's not required. Installation can be done with the cab still on the truck.
Take a look at the BD-Power Dodge APPS Noise Isolator. Interference in the throttle position sensor circuits (APPS) on Dodge Cummins engines from 1994 to 2005 will create false voltage readings in the APPS circuit and cause the lock-up torque converter to rapidly cycle on and off as you drive. This quick and easy fix removes the annoying and potentially harmful RF interference.

Programmers are safe on all stock engines as long as the vehicle is being operated properly. The diesel engines found in our trucks are more than capable of handling the additional power, and often yield increases in fuel economy as well. Like most performance programmers or modules, they may raise EGT's slightly. The slight increase is nothing to be concerned about as long as the truck is being driven normally and not being abused. That being said, it's always highly recommended to have a set of gauges to monitor your temperatures even on stock, non-modified applications. (We recommend the Superchips 3841 F4 Flashpaq. This Superchips is 50 state legal and offers both Gas and Diesel CARB #’s. Click Here)
Can I install studs by pulling one headbolt at a time with out removing heads?
View Staff Answer
Answer
It can be done, but it’s not recommend. The heads should really be taken off to be checked and gaskets replaced.

What is the difference in these studs compared to the more expensive studs?
View Staff Answer
Answer
The normal ARP studs are made of a proprietary ARP 2000 material that has a 220,000 psi tensile strength and provide the clamping force required to keep cylinder heads from lifting due to exceptionally high combustion pressures. The 625 ARP stud kits are made of a Custom Age 625+® material that has a minimum rating of 260,000 psi tensile strength and are often used in heavy HP racing and sled pulling applications.
