JE Pistons GM LS3 LS4 Stroker SRP Pro 2618 Pistons - Set of 8

If you're building a high-performance GM LS engine, especially one that's going to see a lot of abuse or boosted applications, you need pistons that can handle the stress. These JE Pistons SRP Pro 2618 pistons are designed for just that. They're forged from 2618 aluminum, a material known for its exceptional strength and durability, making them a solid choice for stroker builds or engines pushing serious horsepower.

JE Pistons has put a lot of thought into the design of these pistons. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by minimizing skirt width. The ring groove placement is proven to maintain a good seal even in high-horsepower, boosted situations, and the top land thickness is stout for added strength. An accumulator groove is included to help manage combustion gas pressure, which can reduce ring flutter and keep your rings sealing consistently for reliable power delivery. Plus, a low-friction skirt coating is applied to reduce wear, quiet down operation, and optimize performance. These pistons are made 100% in the USA, ensuring a well-built product you can trust.

This set includes everything you need to get started: eight pistons, gas-nitrided carbon steel piston rings, wrist pins, and locks. They're designed for a 4.000-inch bore and feature an inverted dome/dish design. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious LS engine builds, these JE Pistons offer a strong foundation.
