Description

This JE "Pro Series" piston kit is designed for demanding high-performance applications. It features purpose-built forging designs that reduce overall piston weight without sacrificing strength or durability. Internal and external strut braces reduce stress and improve ring groove flatness for improved ring seal. This version uses a 2-ring design for less friction and more power. It also features a low friction skirt, ultra-lightweight construction, hand de-burred finish, 2618-T6 Forging, and FSR Design. Pin, locks, and JE Pro Seal piston rings are included.
