If you're diving into the world of big block Chevy engines, you'll want to check out the ARP BB Chevy .496cu Rocker Arm Stud Kit. This isn't just any kit; it's built for those who appreciate the finer points of performance and reliability. I’ve had my fair share of experiences with rocker arm studs, and let me tell you, these ones have really impressed me.
First off, the base thread size is M10 x 1.50mm, which is pretty standard but crucial for ensuring a solid fit. You don’t want any wiggle in your setup, especially when you’re pushing your engine to its limits. The rocker arm nut thread size is 7/16-20 in., and it’s got a thread length of 0.600 inches. That’s just enough to give you a confident grip without being overly long. It’s all about balance, right?
Now, if you’re wondering about the effective stud length, it comes in at 1.750 inches. This length is designed to accommodate various setups, giving you flexibility whether you’re running stock or aftermarket parts. And speaking of flexibility, the base thread length is 0.750 inches, which ensures that everything stays snug and secure during operation.
What really stands out for me is the fact that this kit is sold as a set of 16. That means you’re getting a complete package without having to hunt down extra studs. It’s the little things like this that make a big difference when you’re in the thick of an engine build. You want to spend your time enjoying the process, not scrambling for parts.
In short, if you’re looking for something that’s going to hold up under pressure and keep your rocker arms in check, this ARP kit is worth a look. It’s got the specs and the build quality that enthusiasts like us appreciate. Trust me, once you’ve got these installed, you’ll feel the difference on the road—or on the track.

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.
