ARP Bolts ARP Mopar 12-Point Head Stud Kit 8740 Chromoly Black Oxide Finish - 144-4201

If you’re looking to beef up your Mopar engine, the ARP Mopar 12-Point Head Stud Kit is a solid choice that’s got some serious muscle behind it. I’ve used these studs on my own ride, and let me tell you, they make a noticeable difference in performance and reliability.

First off, these studs are made from 8740 chromoly steel, which is a fancy way of saying they’re built to last. This material is known for its strength and durability, so you can trust that they’ll hold up under pressure. The black oxide finish not only looks slick but also provides some added protection against corrosion—always a plus when you’re out there pushing your limits.

Now, let’s talk about the 12-point head style. This design gives you a better grip when you’re torquing things down, which means you can get a more accurate fit and avoid any potential headaches down the road. And yes, the kit comes with washers included, so you won’t have to hunt around for those when you’re ready to install.

One thing to keep in mind is that these studs are a fastener style: stud, and they don’t come with an undercut, but honestly, that’s not a deal-breaker. They’re designed to fit right in without any cutting or fitting hassle, which is a relief when you’re in the middle of a build.

Overall, if you want to ensure your engine is locked down tight and ready to take on whatever you throw at it, this ARP head stud kit is a smart investment. You won’t regret it when you feel the difference in power and stability. Trust me, your engine will thank you.

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.
