If you’re diving into some serious upgrades for your Ford 6.7L Diesel, the 150-2901 ARP Flexplate Bolt Kit is a must-have. These bolts are crafted from chromoly, which is a fancy way of saying they’re built to last. I’ve used plenty of fasteners in my day, but there’s something about the strength and durability of these that just feels right. With a yield strength of 180,000 psi, you can trust they’ll hold up under pressure, whether you’re towing heavy loads or just cruising down the highway.
One of the standout features is the black oxide finish. Not only does it look slick, but it also provides a layer of protection against rust and corrosion. You don’t want to be worrying about your bolts when you’re out on the road, right? The 12-point head style makes it easy to get a solid grip, so you can torque them down without stripping anything. And speaking of size, these bad boys come in at 12mm x 1.50—perfect for a snug fit.
Now, let’s talk about the length. With an underhead length of 1.825 inches, these bolts are designed to sit just right, ensuring you get the best connection without any fuss. Plus, you won’t be left hunting for washers; they’re included in the kit. You’ll get a set of 10 bolts, which is just what you need to get that flexplate secured properly.
In short, if you’re serious about your build and want something that’s going to hold up, this ARP kit is worth every penny. It’s not just about getting the job done; it’s about doing it right. Trust me, you’ll appreciate the difference when you hit the road.

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.
