If you're diving into the world of performance upgrades for your Ford 6.0L, you might want to check out the ARP Main Stud Kit (150-5801). This isn't just any set of bolts; it's a solid piece of engineering designed for those who demand reliability and strength from their engine components.
First off, these main studs come with a 4-bolt style, which is pretty standard but crucial for ensuring everything stays locked down when you're pushing your engine to its limits. The stud fastener style makes installation a breeze, and trust me, once you’ve had a taste of how easy it is to work with studs, you won’t want to go back to bolts.
Now, let’s talk nuts—no, not the kind you eat. These studs come with standard 12-point nuts that fit snugly and give you that extra peace of mind when you’re tightening things up. You won't find any windage tray compatibility here, but honestly, that’s not a dealbreaker for most folks who are focused on performance.
What’s really impressive is the yield strength of these fasteners, clocking in at a whopping 190,000 psi. That means they can handle some serious pressure without flinching, which is exactly what you want when you're pushing your engine hard on the track or out on the trails.
Oh, and yes, the nuts are included, so you won’t have to scramble around looking for the right ones. Just keep in mind that washers aren’t part of the package, but you probably have a stash lying around anyway.
In short, the ARP 150-5801 Main Stud Kit is a must-have for anyone serious about their Ford 6.0L build. It’s built tough, easy to install, and gives you that added confidence when you’re cranking up the power. If you want your engine to perform at its best, this kit is worth considering.

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless.
Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.
What Makes ARP Bolts So Special?Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes.
ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.
ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
