These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability in high-stress environments. The assembly includes forged 4032 Icon pistons with a -3.7cc flat top design and a 4.040-inch bore size, paired with plasma-moly standard gap rings for efficient sealing. King XP rod and main bearings are also included, offering solid performance for the rotating assembly's critical journals.
