If you’re diving into the world of performance upgrades for your Holden V8, you’re going to want to check out the ARP 105-2101 manifold bolt kit. These bolts are built to last and designed with serious strength in mind. ARP has been in the game since '68, and they know a thing or two about fasteners that can handle the heat—literally and figuratively. Whether you're pushing your engine to its limits on the track or just want peace of mind on the street, these bolts won't let you down.
What sets these bad boys apart? For starters, the socket size is 3/8 with a 12-point design, which means you’re getting a solid grip for installation.

Plus, the strength of these bolts is no joke. They’re designed to handle extreme loads, which is essential if you're planning on pushing your Holden V8 hard. You’ll appreciate the durability, especially if you’re running a high-performance setup or just want to ensure your engine stays in one piece.
In short, if you’re looking to upgrade your manifold bolts, the ARP 105-2101 kit is a solid choice. It’s not just about looks; it’s about reliability and performance when it counts. Trust me, your engine will thank you.

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.
