If you're looking to beef up your engine's bottom end, let me tell you about this ARP SB Chevy LS1 Cast Iron Main Stud Kit. It’s not just another set of bolts; it’s a serious upgrade for anyone who’s pushing their ride to the limits. With a 6-bolt main style, you get that extra security and peace of mind when you're out on the track or tearing up the streets.
Now, these studs are designed with performance in mind. The fastener style is stud, which means they offer better clamping force compared to regular bolts. You’ll appreciate that when you’re cranking up the horsepower. And speaking of strength, these bad boys have a yield strength of 200,000 psi, so you know they can handle whatever you throw at them. No more worrying about your engine coming apart at high RPMs.
The standard hex fastener nut style makes installation straightforward, and yeah, nuts are included in the kit, so you won’t be scrambling to find the right ones. Just a heads up, though—washers aren’t included, so you might want to grab those separately if you need them.
This kit is compatible with a range of models, including the Chevrolet Camaro from ’98 to ’02, the Corvette from ’97 to ’04, the Pontiac Firebird from ’98 to ’02, and the Pontiac GTO from 2004. It works seamlessly with a windage tray, too, which is a nice touch if you’re looking to optimize oil control during hard cornering.
In short, if you're serious about your build and want to ensure your crankcase stays intact under pressure, this ARP main stud kit is a solid choice. I’ve seen too many engines fail due to weak hardware, and this is one area where you definitely want to invest in quality.

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.
