ARP Moroso 64919 Pro Series Carb Stud Kit with 1in Spacer Plate, 5/16in Chromoly, Black Oxide - 300-2420

If you're diving into the world of performance tuning, you’re going to want to check out the ARP Moroso 64919 Dual Return Spring Carb Stud Kit. This isn’t just another set of fasteners; it’s a solid upgrade that makes a real difference in how your engine breathes and performs.

Let’s break it down a bit. First off, the fasteners are made from chromoly, which is a fancy way of saying they’re tough as nails. You won’t have to worry about them snapping or stripping out under pressure. Plus, they come finished in black oxide, which not only looks sleek but also provides some corrosion resistance. That’s a win in my book.

Now, if you’re curious about the specifics, these studs have a thread size of 5/16 in., which is pretty standard for most setups. The kit includes standard hex nuts and washers, so you’ve got everything you need right out of the box. And you’re getting a set of four, which is perfect for your dual return spring setup.

Speaking of which, the dual return springs are a game changer. They help maintain consistent pressure on your carburetor, which means better throttle response and smoother operation. If you’re running a more aggressive cam or just want to make sure your engine is dialed in, this kit is a solid choice.

Oh, and if you’re worried about fitment, I’ve seen these work well on setups where you’re pushing some serious power. Just make sure to double-check your specs before you dive in. It’s always better to be safe than sorry, right?

So, if you’re ready to step up your game and make sure your carb setup is rock solid, grab this ARP Moroso kit. It’s not just about looks; it’s about performance that you can feel.

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.
