If you're diving into the world of diesel performance, you probably know that the fasteners holding everything together are just as crucial as the engine itself. ARP has been in the game since 1968, and they know a thing or two about making sure your setup can take the heat—and the torque. Their BMC B-Series 3-Main Main Stud Kit (part number 206-5402) is designed specifically for those who want to push their diesel engines to the limit without worrying about the integrity of their components.
What sets these studs apart? For starters, they're built to handle some serious loads. We're talking about head studs and bolts, main studs and bolts, and driveline fasteners that are engineered to be stronger than ever. The installation pre-loads are high, meaning these studs are stretched during installation to ensure a tight fit that can withstand the rigors of heavy-duty use. You won’t have to think twice about whether these will hold up during a high-stakes pull or a race day.
Now, let’s get into the nitty-gritty. The socket sizes for these studs are 3/4 hex and 3/16 Allen, so make sure your toolbox is ready. This kit is perfect for anyone looking to upgrade their main studs without cutting corners. It’s all about reliability here—when you’re pushing your diesel to the max, you want to know that every component is up to the task.
So, if you're serious about your diesel performance and want to ensure your engine is built to last, give the ARP BMC B-Series Main Stud Kit a look. It’s a solid investment for anyone who knows that the little things make a huge difference.

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.
