ARP Bolts ARP Mopar 273-440 Wedge V8 12pt Head 2-Bolt Main Stud Kit with Washers - 140-5003

If you're diving into a build with a Mopar 273-440 Wedge V8, you know the importance of having solid hardware. That’s where the ARP 140-5003 2-Bolt Main Stud Kit comes into play. This isn't just any kit; it's designed for those who want to push their engines to the limit without worrying about the little things, like whether or not your main studs can handle the pressure.

First off, let’s talk about the 2-bolt main style. This setup is a classic for a reason—it provides the right balance of strength and reliability. The fasteners come in a hex head style, which makes installation a breeze. You won’t be fumbling around with weird shapes or sizes when you’re trying to get everything tightened down just right.

Now, if you’re concerned about strength, you’ll be glad to know these studs have a yield strength of 190,000 psi. That means they can take a beating and still hold your engine together when you’re pushing it hard on the track or the street. It’s peace of mind knowing that your engine is secured with some serious hardware.

One thing to note is that this kit doesn’t come with nuts, but it does include washers, which is a nice touch. Those little details matter when you’re assembling your engine, and having quality washers can help distribute the load evenly, preventing any unwanted stress on the studs.

So, if you’re looking to upgrade or replace your main studs, this ARP kit is a solid choice. It’s built for the serious enthusiast who demands performance and durability. Trust me, once you have these in your build, you’ll feel the difference in both confidence and performance.

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.
