If you're diving into the world of diesel performance, you've probably heard of ARP. They've been at it since 1968, and trust me, they know a thing or two about fasteners. These aren't just any nuts and bolts; we're talking about serious hardware designed to handle the crazy loads that come with high-performance diesel engines.

The ARP 9/16-12in 12pt Black Nut Kit is a must-have for anyone looking to beef up their setup. With a socket size of 11/16 and 12-point design, these nuts provide a solid grip and are built to withstand the extreme pressures you might encounter. You won't have to worry about them failing when the going gets tough.

What sets these apart? They’re engineered to handle high installation pre-loads, which means they stretch a bit during installation to create a rock-solid hold. This is crucial when you’re pushing your diesel to the limit. Whether you’re racing or just want your daily driver to perform like a champ, these fasteners are designed to keep everything in check.

And let’s be real, when you're in the garage, you want parts that fit right and work right. No fuss, no drama. This kit is perfect for those looking to upgrade their head studs, main studs, or driveline components. Just know that these are meant for serious applications, so if you’re planning on pushing your rig hard, you’ll want to have these in your toolkit.

So, if you’re ready to take your diesel game to the next level, grab the ARP Black Nut Kit. It’s not just about looks; it’s about performance and reliability. Get ready to feel the difference.

The Story Behind ARP Bolts

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.
