If you're diving into the world of diesel engines, you’ve probably heard about ARP. They’ve been pushing the envelope on fastener design since 1968, and trust me, they know what they’re doing. When it comes to the Nissan YD25, their main stud kit is a game changer. These studs are built to handle some serious stress, which is crucial when you're cranking up the power on your rig.
What makes these studs stand out? For starters, they’re engineered to withstand the extreme loads that come with diesel performance. This means you can push your engine harder without worrying about those fasteners letting you down. The installation preload is high, which means when you torque these bad boys down, they stretch just right to hold everything in place. No more worrying about blown head gaskets or loose bolts when you’re out on the road—or off it!
Now, let’s talk specs. You’ll need a 12mm 12-point socket and a 4mm Allen wrench to get these installed. It’s pretty straightforward, but if you’re not comfortable with wrenching, maybe grab a buddy who is, or hit up a local shop. Once these are in, you’ll notice a difference in how your engine runs, especially if you’ve been pushing it hard. They work wonders for keeping everything tight and secure under pressure.
So, if you’re looking to beef up your Nissan YD25’s internals, this ARP main stud kit is a solid choice. It’s not just about performance; it’s about reliability when you really need it. Don’t skimp on the hardware when you're building something that needs to last.

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.
