If you're diving into the world of high-performance diesel engines, you’ve probably heard of ARP. They’ve been in the game since 1968, and let me tell you, they’ve really nailed the art of race fasteners. I’ve been using their products for a while now, and the difference is night and day when it comes to durability and strength.

Take the ARP Big Block Brodix 14.5 Degree Head Stud Kit (part number 235-4320), for example. These aren’t just your run-of-the-mill fasteners. They’re designed to handle some serious loads, which is crucial when you’re pushing your engine to its limits. The head studs and bolts in this kit are engineered to be stronger than ever, so you can trust that they’ll keep everything tightly secured, even under extreme conditions.

One of the standout features of these studs is the high installation pre-load. What does that mean for you? Simply put, it’s the amount the fastener is stretched during installation. Higher pre-load means better clamping force, which translates to less chance of blowouts or leaks when you're really pushing your engine hard. That’s a huge plus when you’re out on the track or tackling tough terrain.

And let’s not forget about the specs. You’ll need a 1/2 inch 12-point socket and a 3/16 Allen wrench for installation. It’s straightforward, but don’t underestimate the importance of having the right tools on hand. Trust me, it makes the whole process a lot smoother.

In short, if you’re looking to beef up your big block setup, this ARP head stud kit is where it’s at. It’s reliable, tough, and built for performance. You won’t regret investing in something that’s designed to last.

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.
