Keep Yer Head On: ARP® Head Std Kit For Highly Boosted 6.7L Powerstroke V8

Keep Yer Head On: ARP® Head Std Kit For Highly Boosted 6.7L Powerstroke V8

We don’t know much around here but we do know that boost is awesome, that diesel engines are stupidly strong these days, and that ARP makes the best fasteners in the automotive world. The company that is always looking to give their customers an edge and always looking to make new and innovative products has just introduced a head stud kit for highly boosted 6.7L Powerstroke Ford diesel engines.

The factory bolts can only take you so far and with the way guys are compound boosting diesels in 2019, lifting the heads is a big problem. The factory fasteners just do not have the strength and they stretch once that happens, the boost escapes, the coolant starts intermingling with combustion chambers, and it’s all sadness.

Using the best processes and materials, ARP has your problem solved here. Seriously, if you are hot rodding a 6.7L Powerstroke, now’s the time to do the head stud upgrade!


Diesel performance enthusiasts can now take the popular 6.7L Ford Powerstroke engines to new boost levels thanks to ARP introducing head studs made from Custom Age 625+ material—which is nominally rated at 260,000 psi tensile strength.

The special alloy is just one of the important factors that enable the studs to cope with extreme combustion pressures. Studs are centerless ground, then through-hardened in special vertical racks to assure total penetration and optimum ductility. Threads are rolled after heat-treat, which improves their fatigue life tenfold. And they’re made to stringent AS8879D specification to assure precise engagement. All manufacturing is done in-house at ARP’s California facilities to facilitate maximum quality control.

Carrying ARP part number 250-4302, the kit includes studs, parallel-ground washers and 12-point nuts—as well as a packet of ARP Ultra-Torque fastener lubricant. And, unlike OEM torque-to-yield bolts, ARP studs are designed to be re- used.

There’s a lot to choose from when selecting a rec-utility ATV. Do you need 4WD? Will you be using it primarily for work or trail riding? How much power do you need? Do you need a youth model or two so the kids can tag along to help with chores? We’ve prepared a list of several ATVs from leading manufacturers, and each model has anywhere from one to seven trim levels.
