If you’re diving into a header swap for your small-block Chevy, you’ll want to check out the ARP SB Chevy SS 12pt Header Bolt Kit. These aren’t just your run-of-the-mill bolts; they’re crafted with some serious attention to detail. Each bolt is made from polished stainless steel, so not only do they look sharp, but they’re also built to withstand the heat and corrosion that comes with high-performance setups.

The thread size is 3/8-16, and the underhead length comes in at a cool inch (25mm for those who prefer metric). This is a perfect fit for your headers, ensuring a snug and leak-free seal. Plus, they come in a set of 12, so you’ve got enough to tackle your entire setup without having to hunt for extras.

What really stands out is the quality. ARP is known for their durability, and these bolts are no exception. If you’re looking to upgrade your ride and want something that’s going to stand the test of time, these are the bolts you want.

The Story Behind ARP Bolts

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.
