Diamond Pistons Competition Series Pistons

5.0 out of 5 stars 1 Customer Reviews

Diamond Pistons Competition Series pistons are for those looking to take their engine to a whole new level of power. These forged aluminum pistons are superior in strength and provide extra protection during the high-stresses of high-compression, forced induction, or nitrous.

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)
