If you're diving into some serious engine work on your 2010-2013 Hyundai Genesis Coupe, you might want to check out this ARP head stud kit. It's not just any kit; it's designed for the 2.0L G4KF Turbo engine, and trust me, it makes a difference.
First off, let's talk about the materials. These studs are made from 8740 chromoly, which is a fancy way of saying they're super strong and resistant to stretching under high stress. That’s crucial if you're pushing your engine hard. The black oxide finish not only looks sleek but also helps with corrosion resistance, so you won’t have to worry about rust messing with your setup.
The fastener style is stud, which gives you a solid grip and makes installation a breeze. No undercut here, so you know you’re getting a straightforward, reliable fit. The head style is 12-point, which means you’ll have an easier time getting a wrench on them in tight spaces—always a plus when you're elbow-deep in an engine bay.
And yes, washers are included! They’re flat with a 60-degree seat, ensuring a snug fit that keeps everything in place. Just to clarify, this kit is cut to fit for your specific application, so you won’t be trimming or modifying anything to make it work. It’s all about getting that perfect fit right out of the box.
So, if you're looking to boost your Genesis Coupe's performance and reliability, this ARP head stud kit is a solid choice. It’s built to handle the heat, literally, and will keep your engine together when you really push it. Just a heads up, make sure you’re set up for the 2.0L G4KF Turbo—this kit is made for it and won’t fit anything else.

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.
