JE PISTONS Piston Kit 177239

When you're pushing your engine to the limit in competition, every component needs to withstand extreme pressure and maintain precision under stress. JE Pistons' 177239 kit delivers the durability and performance you demand with forged 2618-T6 aluminum construction specifically engineered for professional racing applications. This is the piston upgrade serious competitors choose when reliability and peak performance are non-negotiable.

The Pro Series design incorporates internal and external bracing along with specialized internal milling of the struts—weight reduction strategies that translate to faster acceleration and reduced inertial loads on your engine. The smooth dome and dish features require zero deburring, meaning you get precision-finished parts ready for immediate installation. Everything you need comes included: pistons, pins, pin fitment locks, and rings.
