Description

JE Pistons FSR tour series GP pistons are a lightweight design specifically made for naturally aspirated Circle Track or drag race applications up to 650 hp. Their ring package has been raised for maximum efficiency. These pistons are an aggressive, competition-only design, not intended for street or nitrous use. Their ring grooves are precision-machined for .043, .043, 3.0mm rings and their valve reliefs will accommodate angle-milled aftermarket cylinder heads.
