Description

JE Pistons asymmetrical FSR (Forged Side Relief) piston line incorporates modern forging design with a larger skirt on the major thrust side and smaller, friction-reducing skirt on the minor thrust side. Combined with precision CNC machining, the result is a high-strength, lightweight piston that is extremely durable. These pistons are for GM LS Asymmetrical FSR Flat Top 4.065 Bore engines, specifically LS3 426. They are machined for 1.2mm, 1.5mm, 3.0mm rings (rings not included).
