ARP Bolts ARP Ford Modular 4.6L 2V 2-Bolt Main Stud Kit with Nuts and Washers - 156-5401

If you’re diving into a build with your Ford Modular 4.6L 2V, you’re going to want to check out the 156-5401 ARP Main Stud Kit. This isn’t just another set of fasteners; it’s a solid investment for anyone serious about their engine setup. The 2-bolt main style is designed to give you that extra peace of mind when you’re pushing your engine to its limits.

What I really appreciate about this kit is the stud fastener style. It makes installation a breeze and ensures that everything stays snug and secure, even under the most demanding conditions. Plus, you’ve got standard hex nuts included, so you won't be scrambling for the right tools when it’s time to torque things down.

Now, if you’re wondering about strength, these studs are no joke. With a yield strength of 200,000 psi, you can trust that they’re built to handle some serious power. Just imagine the confidence you’ll have knowing your main studs are up to the task, especially if you’re planning on adding some serious horsepower down the line.

And don’t worry about any extras; the kit comes with both nuts and washers, so you’ve got everything you need right out of the box. Just a heads up, though—this kit doesn’t work with a windage tray, so if that’s part of your plan, you might need to rethink your setup.

In short, if you’re looking to give your engine the robust support it deserves, the ARP Main Stud Kit is a no-brainer. It’s reliable, easy to install, and built to last. Trust me, once you get these in your build, you’ll 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.
