Building or rebuilding a classic Ford Inline 6 engine? You need strong, reliable fasteners. This ARP Main Stud Kit (part number 152-5401) is the go-to choice for serious engine builders. It's specifically designed for Ford's 2-bolt main bearing caps on the 240 and 300 cubic inch inline-6 engines. ARP studs are famous in the performance world for being way stronger than stock bolts, which helps keep everything aligned and secure under pressure, preventing main cap walk and ensuring a solid seal. This kit includes all the studs you need for the job. They're made right here in the USA with high-quality materials and precision manufacturing. If you're aiming for durability and peace of mind in your build, whether it's for a restoration, a truck, or a performance project, these ARP studs are a smart investment. Just remember, this is the stud kit only – you'll need the matching nuts (usually sold separately) to complete the installation.
