If you’re diving into the world of Subaru performance, you know that every little detail counts. That’s where the ARP Pro Series Rod Bolt Kit comes into play, especially if you’re working on a 2.5L WRX from '06 to '07 or an STI from '04 to '07. These aren’t just any rod bolts; they’re crafted from ARP2000 alloy, which means they can handle some serious stress. With a yield strength of 200,000 psi, you can trust that these bolts will keep your engine together, even when you’re pushing it to its limits.
Let’s talk about the fit. This kit is designed to work seamlessly with a variety of models, including the Subaru Baja (2004-2006), Forester (2008), Impreza (2004-2005 & 2008-2012), and of course, the WRX and STI. So if you’re swapping out your connecting rods or just doing some preventative maintenance, you’ll want to grab a set of these. Just keep in mind, they come as a set of 8, but you’ll need to pick up the nuts separately.
The cap screw retention style and E head style of these bolts make installation straightforward, even if you’re not a pro mechanic. I’ve used these in my builds, and I can tell you from experience that they make a noticeable difference in engine stability. If you’re serious about performance and reliability, this is one upgrade you won’t regret.

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.
