JE Pistons LS Series Flat Top Pistons
JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for domestic applications, and they have been performance-proven in victory lane time and time again with the ultimate combination of durability and performance. JE Pistons LS Series flat top pistons are single replacements. Available in different bore sizes for right or left, the pistons are specifically engineered for extreme applications up to, and including, professional competition. In such environments, the higher compression ratios and boost necessitate the high-tensile strength of forged 2618 aluminum construction. The skirts feature a proprietary Forged Side Relief (FSR) forging design that minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin. High-quality, case hardened 5115 low carbon steel wrist pins and retainers are included. Equip your engine with the best in forged pistons—JE Pistons.

JE Pistons LS Series 15-Degree Dome Pistons
One of the best forged pistons for your high performance LS engine, JE Pistons 15-degree domed pistons. They feature JE's FSR (forged side relief) engineered for today's high-power normally aspirated and forced induction LS engines. The exclusive asymmetrical skirt maintains a larger skirt area on the heavily stressed major thrust side, while reducing friction with a smaller skirt on the minor thrust side. The result is high-strength, lightweight pistons that outperform the competition. Select the LS Series pistons needed for your performance setup. Features: * Designed with 15-degree valve pockets * Accumulator grooves * Double pin oilers * Offset wrist pin * Includes round wire locks * Designed for 1.2/1.5/3mm and 1.5/1.5/3mm rings
