Engine building essentials: Summit Racing™ Pro LS Forged Pistons Run boost or nitrous with confi dence! Our Pro LS forged 2618 aluminum alloy pistons are made with profi led and coated skirts, generous valve reliefs that work with both cathedral port and rectangle port heads, and maximized ring lands. The 21⁄4" chromium steel pins clear the reluctor ring in stroker applications. Rings sold separately (see below). Hundreds of applications available for 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L in a variety of bore sizes and compression ratios—for complete details and Made in the USA status visit SummitRacing.com, or call us. Summit Racing Pro LS forged pistons, set of 8 .....................................from $609.99 Summit Racing Pro LS Piston Rings Our premium pistons are designed to work best with premium piston rings…like these! The plasma moly-faced steel top rings withstand boost and nitrous, while the martensitic ductile Napier-hook secondary rings add strength and oil control. Sets also include 3mm oil rings, and all rings are fi le fi t for maximum sealing. Summit Racing Pro LS piston rings, set of 8 .........................................from $140.99 Keith Black Hyper Series Pistons Crafted from a high-silicon, heat- treated hypereutectic aluminum alloy, Hyper Series pistons from Keith Black are light enough to improve throttle response, and strong enough to withstand the pressures and temperatures of competition. They feature fully machined crowns and valve reliefs, accumulator grooves, proprietary diamond-fi nished skirts, drilled oil returns, and CNC-machined pin bores. This all adds up to a tighter fi t that increases ring seal, reduces blow-by, improves oil control, and eliminates cold startup knock. Pistons come with triple spiral locks and work with press fi t or fl oating pins. Sets available for 4- to 8-cylinder engines in standard or oversize bores, in a variety of fl at top, dish, and dome styles. Pins and piston rings sold separately.

Hyper Series pistons, set ........................................................................from $382.99 Summit Racing™ Coated Hypereutectic Pistons Our Summit coated hypereutectic aluminum alloy pistons expand less than cast pistons for tighter piston-to-wall clearances and reduced blowby. Each piston receives a T5 heat treatment for greater strength, plus a special skirt coating to reduce scuffing, seizing, and thermal wear. All pistons have diamond-finished skirts and use 5/64" top, 5/64" secondary, and 3/16" oil control rings (sold separately). Pins included. Available for standard 4.000" bores, as well as .030", .040", and .060" oversizes. Compression ratios listed are calculated with a .040" head gasket.
