Overview 

The UEM Icon Elite pistons are precision-engineered for high-performance GM LS2, LS3, LSA, and LS9 engines with 6.0L and 6.2L displacements. Featuring a 4.070" bore and 4.000" stroke, these pistons are built from 2618 forged aluminum for superior strength and thermal resistance, making them ideal for demanding street or race applications, including forced induction and nitrous builds. The -8cc dished top design provides a moderate compression ratio suited for power-adder setups. Each piston includes CNC-machined valve reliefs for precise fitment, an anodized crown and top land for added heat protection, and accumulator grooves to reduce ring flutter and enhance sealing. Offset wrist pins reduce piston slap and noise, while the M42 coated skirts minimize friction and wear. Designed to work with 6.125" rods, .927" wrist pins, and a 9.240" deck height, these pistons also feature a 15° valve angle and a 1.115" compression height, ensuring compatibility with a wide range of performance LS builds.
