Description

Diamond Pistons Sport Compact Series pistons are ideal for either the street or the drag strip. These forged aluminum pistons are significantly stronger than the factory pistons allowing your engine to handle that extra horsepower.

Diamond Pistons Sport Compact Series pistons feature:

* 3D milling on piston crowns for "ready to install" finish
* Side gas ports for better ring seal
* Moly skirt coating for friction-loss and skirt-wear protection
* Oversized valve pockets for "larger than stock" valve sizes
* Forged 2618 or 4032 aluminum alloy (where specified)
* Premium 8620 or H-13 steel wrist pins (where specified)
