If you’re diving into a build with a Chrysler BB Hemi or Wedge engine, you’ll want to make sure you’ve got the right hardware to keep everything locked down tight. That’s where the ARP BB Chrysler/WP Hemi/Wedge Main Stud Kit comes in. This isn’t just any kit; it’s designed for serious performance and durability.
First off, let’s talk about the 4-bolt main style. This setup is solid and reliable, giving you the peace of mind you need when you’re pushing your engine to its limits. The stud fastener style allows for easier installation and removal, which is a real lifesaver when you’re working in tight spaces or just need to make adjustments on the fly.
Now, you might be wondering about the nuts and washers. Good news—they're all included! You get standard hex nuts that fit perfectly with the studs, and the washers are there to ensure a snug fit. It’s those little details that make a big difference when you’re assembling your engine.
One of the standout features of this kit is its fastener yield strength, clocking in at an impressive 200,000 psi. That means these studs are built to handle some serious stress without flinching. Whether you’re racing or just cruising around town, you can trust that your engine is held together with some heavy-duty gear.
Keep in mind, this kit doesn’t work with a windage tray, so if you’re planning on adding one, you’ll need to look elsewhere. But for those of us who appreciate a straightforward setup, this kit is sold as a complete package, so you won’t be hunting for missing pieces.
In short, if you’re serious about your build and want reliability backed by top-notch engineering, the ARP Main Stud Kit is a no-brainer. It’s built for the long haul, and you’ll feel the difference when you fire up that engine.

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.
