Overview
The UEM Icon Elite pistons are engineered for GM LS2, LS3, LSA, and LS9 engines with 6.0L and 6.2L displacements, delivering high performance and durability for naturally aspirated and boosted applications. With a 4.010" bore and 4.000" stroke, these pistons feature a flat-top design with 4cc valve reliefs, promoting higher compression ratios and improved efficiency. They are constructed from forged 2618 aluminum, offering excellent strength and thermal stability under high-stress conditions. Each piston includes CNC-machined valve reliefs for precise fitment, an anodized crown and top land for added durability, and accumulator grooves to reduce ring flutter and enhance sealing. The offset wrist pins help reduce piston slap and noise, while the M42 skirt coating minimizes friction and wear. Designed to be compatible with 6.125" connecting rods and .927" wrist pins, the pistons have a compression height of 1.115", a 15° valve angle, and are suitable for use with a 9.240" deck height. Weighing approximately 418 grams (not including the 121g wrist pin), these pistons offer a strong, lightweight solution for serious performance builds.
