If you’re diving into an engine rebuild or just looking to step up the performance of your Toyota, the ARP Main Stud Kit is a solid choice. This kit is designed specifically for the 4AG 16V engines found in the Toyota Celica from '87 to '89, along with a few other classics like the Camry and MR2. You know, the ones that really made a mark in the late '80s.
What sets this kit apart? Well, for starters, it uses a 2-bolt main bolt style that’s tough as nails. The fastener style is a stud, which means installation is straightforward and you won’t have to worry about the typical issues that come with standard bolts. Plus, it comes with standard hex nuts that fit snugly, so you can really crank down on them without any fuss.
One thing to note—this kit doesn’t work with a windage tray, so if you’re planning on adding that to your setup, keep that in mind. But what you do get is a fastener yield strength of 200,000 psi. That’s some serious strength, ensuring your main bearings stay put even under high-stress conditions. Whether you’re racing or just want peace of mind during your daily drive, these studs have got your back.
Oh, and you won’t be left scrambling for parts. The kit includes nuts and washers, so you can get everything you need in one go. It’s sold as a complete kit, which is a nice touch for anyone who hates piecing together components.
To wrap it up, if you’re working on a '88-'91 Camry, '87-'89 Celica, or '85-'89 MR2, this ARP Main Stud Kit is a no-brainer. It’s reliable, easy to install, and built to last. Give your engine the upgrade it deserves.

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.
