New from Summit Racing – the Pro LS Forged Pistons. These pistons are built to handle whatever you throw at them and are available in a wide variety of options. See more details below.
No matter what type of LS engine combination you’re building, there is a Summit Racing Pro LS Forged Piston for it. They’re available for popular crank strokes, connecting-rod lengths, and bore sizes, with compression ratios starting in the mid-9:1 range for boosted engines and up to 11.5:1 for naturally aspirated or nitrous-fed motors. Summit Racing Pro LS pistons are forged from 2618 alloy aluminum and feature chromium steel wrist pins, a piston skirt design with the cam and taper required to ride perfectly in the bore, thick ring lands, and more.
