ARP Bolts ARP LS1 LS2 12pt Thermostat Housing Bolt Kit, Steel, Black Oxide Finish - 134-7401

So, you've got your hands on an LS1 or LS2 engine, huh? That's awesome! If you're diving into a build or just need to replace some worn-out parts, you might want to check out the ARP LS1 LS2 12pt Thermostat Housing Bolt Kit. This isn't just any bolt kit; it's designed for those who appreciate the finer details that make a difference under the hood.

First off, let's talk about the fastener style. We're looking at a solid bolt design here, which means you can trust it to hold everything securely in place. The underhead length measures in at about 0.787 inches, giving you just the right amount of grip without being overkill. And the 12-point head style? That’s not just for show. It provides a better grip for your tools, making it easier to torque down properly without stripping the head.

Now, the material is where things get really interesting. These bolts are made from durable steel, which means they can withstand the heat and stress of your engine without breaking a sweat. Plus, they come with a black oxide finish. This isn’t just for looks; it helps prevent rust and corrosion, keeping your setup looking sharp and functioning well over time.

And let’s not forget, this kit is sold as a complete package, so you won’t be scrambling to find individual pieces when you’re knee-deep in your project. It’s all there, ready to go. If you’re serious about your build and want something that’s going to last, this ARP kit is definitely worth considering. Trust me, once you’ve got these bolts in place, you’ll feel a little more confident every time you fire up that beast.

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.
