Description

Upgrade your Chevrolet LS engine with the JE Pistons Chevrolet LS Gen 3/4 3.898 inch bore forged piston set. Crafted from high-strength 2618 aluminum and manufactured entirely in the USA, these pistons are engineered for demanding performance applications. Designed specifically for each engine model, they offer an optimal balance of durability and power for racing, street performance, or high-performance builds. The set includes eight pistons, each featuring proprietary forged side relief (FSR) design, which minimizes friction and reduces power loss by decreasing skirt width and incorporating a shorter wrist pin for weight savings. This innovative design enhances efficiency and responsiveness during high-stress engine operation. The pistons are equipped with accumulator grooves, which help reduce pressure from combustion gases, thereby decreasing ring flutter and improving ring seal for consistent power output. Depending on your specific application, some pistons include skirt coatings that further reduce friction and wear on both the piston skirts and cylinder walls, contributing to longer engine life and quieter operation. These JE Pistons are a proven choice for enthusiasts seeking reliable performance, whether on the dirt track or drag strip, as their performance has been tested and validated in victory lane many times. Fully forged for strength and precision, the pistons are compatible with high-demand engine builds that require a 3.898 inch bore, making them ideal for custom engine projects aiming for maximum horsepower and longevity. With a focus on quality and performance, JE Pistons ensures that every piston set is made with care and expertise, providing you with a product that meets the highest standards for racing and performance engines.
