If you’re diving into the world of performance upgrades for your Porsche, you can’t overlook the importance of a solid connecting rod setup. I recently got my hands on the ARP Porsche M9 Rod Bolt Kit, and let me tell you, this isn’t just another piece of hardware; it’s a game changer for anyone serious about their engine’s reliability and power.
First off, these bolts are made from 8740 chromoly steel. If you’re not familiar, that means they can handle serious stress without flinching. With a yield strength of 200,000 psi, you can trust that these bad boys will keep everything tightly secured, even when you're pushing your Porsche to its limits. The through-bolt cap retention style is a nice touch too—it just feels more secure, you know? No one wants to worry about their engine parts coming loose while tearing up the track.
Now, let’s talk about the rod bolt head and nut styles. The H style head and hex nut make installation straightforward and allow for easy adjustments down the line. Plus, they come with nuts included, so you won’t find yourself scrambling for extra parts when you’re in the garage.
This kit is designed to fit a variety of Porsche models, including the Porsche 930 from 1978-1979, the Porsche 968 from 1993, and the Porsche 993 C2/C4 from 1994 and 1996-1997. So whether you’re upgrading an old classic or working on a newer model, this kit has got you covered.
In short, if you’re looking to enhance your engine’s performance and reliability, the ARP M9 Rod Bolt Kit is definitely worth considering. I’ve seen the difference it makes firsthand, and it’s a solid investment for anyone who loves their Porsche as much as I do.

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.
