These pistons are made from 2618 aluminum, a material known for its strength and ability to withstand high temperatures. The H-beam connecting rods are paired with 7/16-inch ARP L19 bolts, which are very strong and suitable for high-stress applications. You'll also find plasma-moly file-fit piston rings, allowing you to set the gap precisely for your specific build.
