If you’re digging into some serious diesel work, you’ve probably heard of ARP. They’ve been at it since 1968, pushing the envelope on fastener technology, especially for racing and heavy-duty applications. These guys know their stuff when it comes to creating fasteners that can take a beating and keep on going. That’s where the ARP Lentz Replacement ARP2000 Rod Bolt Kit comes into play.
This isn’t just any rod bolt kit. It’s designed for those who really push their engines to the limit. We’re talking about head studs and bolts, main studs, and driveline components that are built to withstand some serious stress. The strength of these fasteners is impressive, and they’re engineered to handle extreme loads without breaking a sweat. You’ll appreciate the high installation pre-loads, which means these bolts are stretched just right during installation to ensure a tight fit that won’t let you down.
Now, let’s get into the nitty-gritty of the specs. The thread size on these bad boys is a solid 7/16", with an overall length (UHL) of 1.800". The thread length is 0.800", and you’ve got a grip length of 0.300". The head height is about 0.380", which is perfect for those tight spots. You’ll need a 1/2 12pt socket to get these installed, and the collar diameter is 0.655". All of these numbers come together to create a fastener that’s not just tough, but also easy to work with.
In short, if you’re serious about your diesel performance, you’ll want these ARP2000 rod bolts in your toolkit. They’re a solid investment for anyone looking to upgrade their engine’s reliability and performance. Trust me, once you’ve used these, you’ll never look back.

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.
