If you’re diving into some serious engine work, you’ll want to check out the ARP BB Chevy Rocker Arm Stud Kit. This isn’t just any kit; it’s built for those who really care about performance and reliability. I've used these studs in my own builds, and let me tell you, they make a difference.
First off, the base thread size is 7/16-14 inches, which fits perfectly for most big block Chevy setups. The rocker arm nut thread size is 7/16-20 inches, ensuring you get a snug fit that you can trust. You don’t want your rocker arms moving around when you’re pushing your engine to the limit, right?
One of the standout features is the guideplate locator shank. It’s a small detail, but it really helps with alignment, making installation a breeze. You’ll appreciate that when you’re under the hood trying to get everything just right.
Now, let's talk measurements. The rocker arm nut thread length is a solid 1.000 inches, and the effective stud length is 2.000 inches. This means you’ve got plenty of thread engagement to keep things secure. Plus, the base thread length is 1.300 inches for exhaust and 0.820 inches for intake, which is pretty standard but crucial for maintaining that tight seal.
In short, this kit is designed for durability and performance. If you're serious about your build, these studs are a no-brainer. They’ve held up beautifully in my experience, and I’m confident they’ll do the same for you.

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.
