JE Pistons 317230R Forged Piston Kit 90.00mm Bore 10.0:1 Compression UTV Powersports

JE Pistons 317230R is a premium forged piston kit engineered for high-performance UTV and powersports engines. Featuring a 90.00mm bore and 10.0:1 compression ratio, this kit delivers the strength and precision demanded by today's high-output side-by-side and off-road applications.

Forged in the USA from 2618 aluminum alloy, the 317230R provides the high tensile strength required for demanding performance environments — including forced induction, nitrous, and high-revving naturally aspirated builds. JE's proprietary Forged Side Relief (FSR) forging design reduces skirt width to minimize friction and power loss, while a shorter wrist pin saves rotational weight for improved throttle response.

Key Features:
