These pistons are forged from either 4032 or 2168 aluminum alloy and are precisely CNC-machined to their final configuration. Where appropriate, designs incorporate the strength to deal with nitrous, turbos, or blowers. Piston Rings, chromoly wrist pins and Spirolox retainers are included.

Armor Plating - This high performance coating is applied to the piston crown, ring grooves, and piston pin bore. The coating on the dome helps protect the piston from the damage caused by detonation, and will actually harden over time from the heat caused by combustion. This coating is also applied to the ring groove, and helps eliminate micro-welding of the ring, and improve wear of the ring groove along with improving ring seal. The coating in the piston pin bore improves wear, reduces friction, and eliminates material deformation of the lockring groove.
