Description

Diamond Pistons Race Series pistons will withstand some serious horsepower for your high performance engine. These 2618 aluminum pistons are not only significantly lighter than the factory pistons but also superior in strength. The 2618 alloy is specifically for high-horsepower, nitrous, and boosted engines making up to 2,000 hp.

Diamond Pistons Race Series pistons feature:

* 3D milling on piston crowns for "ready to install" finish
* Inside design forging with fully machined underskirts for maximum strength
* Valve pockets designed to work with most aftermarket cylinder heads
* Side gas ports for better ring seal
* Moly skirt coating for friction-loss and skirt-wear protection
* Premium H-13 wrist pins included; chamfered for round wire locks
