The pistons are forged 4032 Mahle units, featuring an 18cc dome and a 4.320-inch bore size, designed to work with the crank and rods for optimal combustion chamber volume and performance. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's specific needs, and King XP rod and main bearings, which offer improved durability and performance for high-stress applications.
