If you're diving into the world of diesel performance, you’ve probably heard of ARP. They’ve been at it since 1968, pushing the boundaries of fastener technology, and let me tell you, their stuff is the real deal. Take the ARP SB Ford 3/8 x 1.670 SS Header Stud Kit, for instance. This isn’t just a bunch of bolts; it’s a thoughtfully designed solution for anyone serious about their engine setup.
These header studs are crafted to handle some serious stress. We’re talking about extreme loads that would make lesser fasteners buckle under pressure. The design is all about strength and reliability, so you can focus on what you love—driving your rig hard without worrying about your hardware giving out.
Now, let’s get into the nitty-gritty. The studs come with a socket size of 7/16 with a 12-point head, which means you’ll have no trouble getting a good grip during installation. They’re a solid 1.670 inches in overall length, and with a thread size of 3/8 inches, these bad boys fit perfectly where you need them. And yeah, they come with nuts and washers included, so you won’t be scrambling to find the right ones when it’s time to put everything together.
What really stands out is the installation pre-load. ARP has designed these fasteners to be stretched during installation, which means they hold tight and won’t loosen up on you. This is crucial for anyone who pushes their diesel to the limit, whether it's on the track or the trails. You want to know your setup is rock-solid, and with ARP, you can trust that it’s built to last.
So if you’re looking to upgrade your header studs, give this ARP kit a shot. It’s not just about the numbers; it’s about the peace of mind that comes with knowing you’ve got top-notch components keeping your engine together.

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.
