If you're diving into a project with a Ford 390-428c.i.d. FE engine, the ARP BB Ford Main Stud Kit (part number 155-5401) is a solid choice. This isn’t just another kit; it’s built for those who know their way around an engine and want something that can handle the heat and pressure.

First off, let’s talk about the basics. This kit features a 2-bolt main style, which is what you want for that extra reliability when you’re pushing your engine. The fasteners are designed as studs, which means you get a more secure fit compared to standard bolts. And yeah, it comes with standard hex nuts and washers, so you won’t be scrambling to find the right parts when it’s time to put everything together.

Now, one of the standout features here is the yield strength of these fasteners—sitting at an impressive 200,000 psi. That’s serious business right there. It means these studs are ready to take on whatever you throw at them, whether you're building a street beast or a track monster.

Keep in mind, this kit doesn’t work with a windage tray, so if you’ve got one in mind, you might want to look elsewhere. But if you’re just looking for a solid main stud setup, this kit has you covered. Plus, it comes as a complete kit, so you get everything you need in one package.

In short, if you’re serious about your build and need something that won’t let you down, this ARP Main Stud Kit is worth considering. It’s built by folks who get it—engine performance matters, and this kit delivers.

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.
