JE Pistons 400SBC ALLPRO/GB2000 Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for serious performance applications. This set is specifically designed for the 400 SBC engine, featuring a 4.135-inch bore and a dome piston design. The 2618 aluminum alloy offers high tensile strength, which is crucial for handling the stresses of high-demand engines where durability and consistent power are paramount.

JE Pistons incorporates several advanced features to maximize performance and longevity. The proprietary Forged Side Relief (FSR) design reduces skirt width, minimizing friction and power loss while also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the cylinder walls, contributing to quieter operation and extended piston life. Every set is forged and machined in the USA, ensuring a high level of manufacturing quality.

This set includes eight pistons, each designed for a 4.135-inch bore with a 1.100-inch compression distance and a 0.927-inch pin diameter. These specifications are critical for proper engine assembly and performance tuning. Please note that this part is not CARB approved and cannot be shipped to California.
