If you're diving into a project with your Chrysler Hemi 5.7 or 6.1L, you know that the little details matter just as much as the big ones. That’s where the ARP 140-1501 Water Pump/Timing Cover Bolt Kit comes into play. This isn’t just any bolt kit; it’s designed specifically for those engines, and trust me, it makes a difference.
First off, these bolts feature a 12-point head style that not only looks sharp but also gives you a solid grip when you're wrenching down. No more worrying about stripping heads or slipping sockets—these bad boys are built for performance. They’re made from 8740 chromoly steel, which means they’re incredibly strong and can handle the heat, literally. The black oxide finish not only adds a sleek look but also provides some corrosion resistance, which is always a plus when you're working in less-than-ideal conditions.
Now, you might notice that there’s no washer included. That’s because these bolts are designed to work perfectly as-is, so you can trust that they’ll hold everything tight without any extra fuss. Each kit comes with everything you need to get your water pump and timing cover securely fastened, so you can focus on what really matters—getting your ride back on the road.
Overall, if you’re looking for reliable, high-quality fasteners that won’t let you down, this ARP kit is a solid choice. It’s been a game changer for my builds, and I can’t recommend it enough. Get those covers secured and hit the road with confidence!

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.
