JE PISTONS Piston Kit 284767

When you're pushing your engine to the limit in competition, stock pistons won't cut it—you need forged aluminum built for extreme loads and sustained high RPM. JE PISTONS' Pro Series 284767 kit delivers the precision machining and internal bracing that separates podium finishes from DNFs. These are purpose-built components engineered by professionals, for professionals.

Every piston in this kit arrives complete with pins, locks, and rings—ready for installation without additional prep work. The 2618-T6 forged aluminum construction handles the thermal cycling and mechanical stress that separates competition engines from street engines, while the smooth-flowing dome geometry and internal struts reduce weight without sacrificing strength.
