Description

Designed with input from leading engine builders and Pro Stock technology, Wiseco introduces its Quick 16 Series pistons for drag racing. They meet the demands of today's big valve, big cubic inch Sportsman series engines. Loaded with features, the pistons include anti-detonation grooves, 15 Pro Stock pressure seal grooves, vertical gas ports, ArmorGlide skirt coating, reinforced decks, and profiled domes for nitrous use.

Wiseco built these pistons on a new generation dedicated forging designed to perform and last round after round, from weekly brackets to Super 16 Shootouts. And since Wiseco produces all their forgings in-house, the pistons are lightweight with extreme durability. The dome configuration is engineered to maintain proper flame travel and desired compression ratios needed for extreme horsepower engines and exotic fuels. It's designed to fit conventional heads from leading manufacturers. Quick 16 pistons have all the features expected for modern day race engines. They're available in compression heights and ring packages for today's most popular combinations and power adders. Pistons and kits come complete with pistons, pins, and Spirolox.
