For the pistons, you get SRP Pro forged 4032 aluminum pistons with an inverted dome design, creating a -10cc volume to achieve a specific compression ratio when paired with the correct cylinder heads and deck height. These pistons are designed for plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. To ensure smooth operation and durability, the kit includes King XP rod and main bearings.
