If you’re diving into the world of Chevy LS1 builds, you’ll want to check out the ARP Chevy LS1 Header Stud Kit. This isn’t just another set of fasteners; it’s the kind of upgrade that makes a real difference when you’re bolting on those headers. Trust me, I’ve been there, and having the right hardware can save you a lot of headaches down the road.
First off, let’s talk about the fastener style. These studs are designed with a stud style that makes installation a breeze. You’ll appreciate the 8mm x 1.25 thread size—it’s the kind of fit that gives you confidence when you’re cranking down those headers. And the 12-point head style? It’s not just for show; it gives you better grip and torque, especially in tight spaces where a regular socket might struggle.
Now, the overall length of 1.750 inches is spot on for most applications, providing just the right amount of engagement without overextending. Made from stainless steel, these studs are tough enough to handle the heat and stress of your engine without rusting or corroding. Plus, the polished finish not only looks great but also helps with easy cleaning and maintenance.
In short, if you’re serious about your build, don’t skimp on the details. The ARP Header Stud Kit is built for durability and performance, so you can focus on what really matters—getting your ride out on the road and enjoying every minute of it.

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.
