ARP M12 x 1.75 x 90 Hex Black Stainless Steel Bolts, 14mm Socket, 5/pkg
$40.95

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 envelope on fastener technology, and trust me, they know what they’re doing. These M12 x 1.75 x 90 Hex Black Stainless Steel Bolts are a testament to that. Designed specifically for the heavy loads that come with high-performance diesel engines, these bolts are built tougher than ever. You really can’t underestimate the importance of reliable fasteners when you’re cranking up the power.

What’s cool about these bolts is the way they handle installation. The pre-loads—the amount the fastener stretches when you’re putting it on—are incredibly high. This means they grip like a champ and won’t let go when the going gets tough. You’ll want to make sure you’re using the right torque value, which is set at 98 ft-lbs (or 132.9 Nm). That’s a solid amount of torque to ensure everything stays locked down, especially if you’re pushing your engine to its limits.

Now, let’s talk specs. These bolts come with a 14mm hex socket size, making them easy to work with. The overall length is 90mm, with a thread length of 30mm and a grip length of 60mm. The thread diameter is M12 x 1.75mm, and the grip diameter is 12mm. Plus, the head height is 11.7mm, and the collar diameter is 21.6mm. All these details matter when you’re fitting them into your setup, ensuring you get that perfect fit for maximum performance.

In short, if you’re looking for fasteners that won’t let you down, these ARP bolts are a solid choice. They come in a pack of five, so you’ll have enough to tackle your project without scrambling for extras. Trust me, once you’ve used ARP, you’ll see why they’re the go-to for serious diesel enthusiasts.

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.
