If you're diving into the world of performance engines, you know that every little detail counts. That’s where the ARP BB Chevy Rocker Arm Stud Kit comes into play. This isn’t just any kit; it’s specifically designed for those of us running aluminum heads, which is a game changer when you’re pushing your engine to the limit.
Let’s talk specs for a second. The base thread size is 7/16-14 inches, and the rocker arm nut thread size is 7/16-20 inches. That means you’re getting a solid, reliable connection that can handle some serious torque. The rocker arm nut thread length is 0.850 inches, which allows for a snug fit without any slippage—something you definitely want when you're revving high.
Now, the effective stud length is 2.350 inches. This length is crucial for ensuring that your rocker arms are positioned just right, allowing for smooth operation and optimal performance. Plus, the base thread length is also 0.850 inches, giving you that extra bit of stability you need when the engine starts to roar.
And here’s the kicker: this kit comes sold as a pair, so you’re all set for both sides of your engine. No need to hunt around for extra parts. Just install and get back to what you love—driving your beast of a machine.
In short, if you’re serious about your build and want to ensure that every component works together like a well-oiled machine, the ARP BB Chevy Rocker Arm Stud Kit is a solid investment. It’s tough, reliable, and designed for those who know that performance is in the details.

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.
