ARP Bolts ARP Ford Modular V8 Main Cap-Side Bolt M8 Kit for Early Cast Iron Block - 156-5201

If you're diving into a project with your early cast iron Ford Modular V8, you might want to check out the 156-5201 ARP Main Cap-Side Bolt Kit. This isn’t just any bolt kit; it’s designed specifically for those who know that the little things can make a big difference in performance and reliability.

First off, let’s talk about the 2-bolt main style. It’s a solid choice for keeping everything in place, especially if you’re pushing your engine to its limits. The stud fastener style means you’re getting a secure fit that can handle some serious torque without stripping out. And those standard 12-point nuts? They’re not just for looks; they allow for a better grip and easier installation, especially in tight spots where a socket might struggle.

Now, if you’re wondering about strength, these bolts don’t mess around. With a yield strength of 200,000 psi, you can trust that they’ll hold up under pressure. That’s crucial if you're planning to push your engine hard, whether it's for racing or just some weekend fun. And yes, you get the nuts and washers included in the kit, so you won’t have to scramble for extra parts when you’re ready to install.

Keep in mind, this kit is sold as a complete package, which means you’re all set to tackle your project without any last-minute runs to the store. Just a heads up, it doesn’t work with a windage tray, so if you’re running one of those, you’ll need to plan accordingly.

In short, if you’re looking for a reliable way to secure your main caps, this ARP kit is a solid investment. It’s built for those who take their builds seriously and want to ensure everything stays tight and right. Trust me, you’ll appreciate the peace of mind that comes with using quality hardware like this.

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.
