ARP Bolts Main Stud Kit for 2007+ Dodge 6.7L Cummins Diesel, 2-Bolt, 190,000 psi - 247-5405

If you're diving into the world of diesel performance, you’ve probably heard of ARP and their reputation for quality. The ARP 247-5405 Main Stud Kit is designed specifically for the 2007 and newer Dodge 6.7L Cummins engines, and let me tell you, it’s a solid upgrade if you’re looking to boost your rig’s reliability and strength.

This kit features a 2-bolt main bolt style, which is perfect for those of us who want to ensure our engine can handle some serious power without the risk of failure. The stud fastener style is a game-changer—studs provide a more consistent clamping load than bolts, which means better stability for your engine components. Plus, the standard 12-point nuts included in the kit make installation a breeze, giving you that added grip when you're torquing everything down.

Now, if you’re wondering about the strength of these fasteners, they boast a yield strength of 190,000 psi. That’s some serious muscle right there. It means you can push your engine without worrying about the main studs letting you down. Just keep in mind, this kit doesn’t work with a windage tray, so if you’ve got one in your setup, you might need to rethink your options.

And yes, the nuts come included, so you won’t be left scrambling for parts when it’s time to get your hands dirty. Just a heads up, though—no washers are included, so make sure you’ve got those on hand if you need them.

All in all, if you're serious about your Cummins and want to ensure it can handle whatever you throw at it, this ARP stud kit is definitely worth considering. It’s built to last and gives you that peace of mind when you’re out on the road or tackling tough jobs. Trust me, once you feel the difference, you’ll wonder how you ever lived without it.

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.
