If you're diving into the world of diesel performance, let me tell you about the ARP M12 x 1.00 12pt Nut Kit. These bad boys have been a go-to in the racing scene since 1968, and for good reason. ARP took the time to really understand what it means to create fasteners that can handle the serious stress of high-performance engines. We're talking about head studs, main studs, and driveline components that are built tougher than ever, designed to withstand the extreme loads that come with cranking up your diesel's power.
Now, let's get into the nitty-gritty. This kit comes with ten nuts, each featuring a 14mm 12-point socket size. That means you’re not just getting any old fasteners; these are precision-engineered to provide a rock-solid connection where it counts. The installation pre-load on these nuts is impressive—they stretch during installation to ensure a tight fit that won't let you down when you're pushing your engine to its limits.
Whether you're upgrading your truck for serious towing or just want to make sure everything is secure under the hood, these nuts are a solid choice. They’re designed to fit snugly, so you won’t have to worry about any slipping or loosening during those heavy-duty tasks. Just make sure you’ve got the right tools on hand—those 14mm sockets will be your best friend!
So, if you’re ready to take your diesel build to the next level, grab this ARP Nut Kit. It’s not just about performance; it’s about reliability. You want parts that are going to hold up when you really need them, and with ARP, you’re getting just that.

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.
