If you’re looking to upgrade your alternator setup, the 300-0502 ARP 7/16in x 5.250 Alternator Stud Kit is worth considering. I’ve had my fair share of alternator issues, and trust me, having the right fasteners can make all the difference.
This kit comes with some solid features that really stand out. First off, the fastener style is a stud design, which means you get a secure fit that’s easy to work with. The thread size is 7/16 inches, which is pretty standard and fits a range of applications. If you’re working on a custom build or just doing some routine maintenance, these studs are versatile enough to handle it.
One thing I appreciate about this kit is the 12-point head style. It gives you more grip compared to standard hex heads, so you can really torque them down without worrying about stripping. And let’s be honest, who hasn’t had that moment of panic when a fastener slips? The steel construction ensures durability, and the black oxide finish not only looks good but also provides some added corrosion resistance. That’s a big plus if you’re working in less-than-ideal conditions.
Plus, the kit is sold as a set, so you’ll have everything you need to get your alternator securely mounted without having to hunt down individual pieces. Overall, if you’re serious about your ride and want something that’s going to last, this alternator stud kit is a solid choice.

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.
