ARP Bolts ARP Oldsmobile 455 2-Bolt Main Bolt Kit with Washers, 180,000 psi Strength - 185-5001

If you’re diving into an Oldsmobile 455 build, you’re probably already aware that the details matter. That’s where the 185-5001 ARP Oldsmobile 455 2-Bolt Main Bolt Kit comes into play. This isn’t just any bolt kit; it’s designed for those who know that strength and reliability can make or break your engine performance.

Let’s talk about the main bolt style first. This kit features a solid 2-bolt design that’s perfect for those looking to keep things simple yet effective. The head style is hex, which means you’ll have no trouble getting a good grip on these bad boys when you’re tightening them down. And while it doesn’t come with nuts, it does include washers, so you can be sure everything sits nice and snug.

Now, if you’re wondering about strength, these bolts are no joke. With a fastener yield strength of 180,000 psi, you can trust that they’ll hold up under pressure—literally. Whether you’re pushing your engine to the limits on the track or just cruising around town, having reliable bolts is crucial.

One thing to keep in mind is that this kit doesn’t work with a windage tray, so if you’re planning on using one, you’ll need to look elsewhere. But for those who want a straightforward, tough-as-nails solution for their Oldsmobile 455, this bolt kit is a solid choice. It’s the kind of gear that gives you peace of mind when you’re under the hood, knowing you’ve got quality components holding everything together.

The Story Behind ARP Bolts

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.
