Description

JE Pistons' asymmetrical FSR (Forged Side Relief) piston line features a larger skirt on the major thrust side and a smaller, friction-reducing skirt on the minor thrust side. This design, combined with CNC machining, results in a high-strength, lightweight, and durable piston. JE Pistons designs, forges, and machines all pistons in-house, offering both off-the-shelf and custom racing pistons. Their 70+ years of racing experience contribute to premium features like full billet construction, EN plating, and purpose-designed coatings.
