If you're diving into a starter swap or just need some solid bolts for your GM setup, the ARP GM 3/8 X 4.400in Hex SS Starter Bolt Kit is worth your attention. These aren’t your run-of-the-mill fasteners; they’re designed with a mini starter style that fits snugly without a fuss.
What I really appreciate about these bolts is the custom 450 material they’re made from. It’s tough as nails and holds up against the wear and tear that comes with high-performance engines. Plus, the polished finish isn’t just for looks—it helps resist corrosion, which is a big deal if you’re working in less-than-ideal conditions.
With an underhead length of 4.400 inches, these bolts provide just the right amount of reach for a secure fit. And let’s be real, no one wants to be stuck on the side of the road because of a starter issue. So having a reliable pair of bolts is crucial, and that’s exactly what you get here. They come sold as a pair, which means you’re set for both sides without any extra hassle.
In short, if you’re looking to upgrade or replace your starter bolts, this kit is a solid choice. It’s practical, durable, and built for the long haul—just like your ride.

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.
