ARP Bolts ARP Thread Cleaning Tap Combo 1.50 & 1.75 for Diesel Fasteners
$185.45

If you’ve ever worked on a diesel engine, you know how crucial it is to have the right fasteners in your toolkit. That’s where ARP comes in. They’ve been in the game since 1968, pushing the envelope on race fastener design, and let me tell you, they’ve nailed it. Their fasteners, especially the head studs and bolts, main studs and bolts, and driveline components, are built to withstand some serious punishment. We're talking about the kind of strength that can handle extreme loads without breaking a sweat.

Take the ARP Thread Cleaning Tap Combo for example. This kit includes taps for both 1.50 and 1.75 threads, making it a must-have for anyone who’s serious about keeping their threads clean and ready for action. When you’re installing those high-performance studs, you want to ensure that the threads are in tip-top shape. A clean thread means a better fit, and that translates to higher pre-loads—essentially, the amount the fastener is stretched during installation. Higher pre-loads mean a more secure hold, which is crucial when you’re dealing with the kind of torque that diesel engines produce.

What I love about ARP is that they don’t just throw around fancy specs; they actually back it up with real-world performance. These fasteners are designed to take the heat, literally and figuratively. If you’re looking to push your diesel to its limits, you’ll want to make sure you’re using the best, and that’s what ARP delivers. So, whether you’re rebuilding an engine or just doing some routine maintenance, this tap combo is a solid investment for keeping your setup running smoothly.

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.
