JE Shelf Pistons 86.5mm Bore 8.5:1 CR | Toyota 2JZGE / 2JZGTE (296932)

JE Asymmetrical FSR Pistons for Toyota 2JZGTE / 86.5mm Bore

JE asymmetrical pistons use a forged-side-relief design (FSR) with major and minor thrust skirts, inboard pin bosses and a shorter and stiffer wrist pin. Over the years, the skirt designs were tweaked, sometimes significantly, as designers refined their function according to changing performance requirements. The primary focus of the asymmetrical piston design is weight and friction reduction via the FSRs smaller, lighter skirt on the minor thrust side. FSR (Forged Side Relief) skirts are actually stronger than full round designs, but they require more fine tuning of the skirt profile to match full round wear characteristics.
