If you're diving into the world of diesel performance, you’ve probably heard of ARP. These guys have been at it since 1968, pushing the envelope on fastener technology. They really know their stuff when it comes to making parts that can take a beating. I mean, think about it—when you’re dealing with high horsepower and torque, you need fasteners that won't let you down. That’s where their exhaust manifold bolts come into play.
The ARP Exhaust Manifold Bolts are designed with the kind of strength you’d expect from a brand that’s been around the block a few times. These M8 x 1.25 x 32mm bolts are part of an 8-piece accessory stud kit that’s perfect for those who want to ensure their setup can handle whatever you throw at it. The broached design means they grip like crazy, which is a huge plus when you’re cranking up the power.
One thing I really appreciate is how ARP has thought about installation. They’ve engineered their fasteners to handle extreme loads, which means you can push your engine without worrying about the integrity of your bolts. The installation pre-loads are high, which means these fasteners stretch just right when you’re tightening them down, ensuring a solid fit that won’t budge under pressure.
For those who like to get hands-on, the socket sizes are 10mm 12pt and 3mm Allen, so you’ll have the tools you need to get these bad boys in place without any fuss. It’s all about making sure you can get the job done right, without needing a degree in engineering to figure it out.
In short, if you’re serious about your diesel setup, you’ll want to consider these ARP bolts. They’re not just another part; they’re a crucial piece of the puzzle that can help you unleash the full potential of your engine.

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.
