Description
These Diamond 21544-RS-8 LS2K 15 Dish Series pistons are are for most of our boosted 427ci LS builds (4.00″ stroke, 4.125″ bore, 6.125″ rod length).
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
We build a broad range of LS engines ranging from naturally aspirated 6.0L street builds to all-out methanol fed race engines with Diamond pistons. If these aren’t what the ones you need, give us a call at 815-725-2727 and we’ll order them for you.
