Diamond Pistons Competition Series features:

* 3D milling on piston crowns for "ready-to-install" finish
* Generous valve pockets designed to work with stock or oversized valves and various cylinder heads
* Constructed from forged 4032 or 2618 aluminum alloy (where specified)
* Premium 8620 or H-13 steel wrist pins (where specified)
