What is the bore size and pin diameter for these pistons?

These pistons have a 4.125 inch bore. The wrist pin diameter is 0.927 inches, and the compression distance is 1.065 inches.

Are these pistons suitable for all LS7 engine builds?

These pistons are designed specifically for LS7 engines and high-demand performance applications. While they are built for durability and performance, always consult your engine builder or refer to JE Pistons' specific application notes to ensure they are the right fit for your particular build.

What are the benefits of the Forged Side Relief (FSR) design?

The FSR design helps minimize friction and power loss by reducing skirt width. It also saves weight by using a shorter wrist pin, contributing to overall engine efficiency and performance.

Product Details

What you get in this kit is a set of eight JE Pistons STROKER DOME pistons, designed specifically for LS7 engines. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons brings over 75 years of experience to the table, focusing on creating pistons that balance durability with performance, proven on tracks from dirt to drag.

JE Pistons uses a proprietary Forged Side Relief (FSR) design. This helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, which also shaves off extra weight. Depending on your specific application, these pistons might also feature an accumulator groove. This groove helps manage combustion gas pressure, reducing ring flutter and improving the seal for more consistent power delivery. Some applications also include a skirt coating, which works to reduce friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life.

These pistons are built for high-demand performance applications, and they are designed specifically for the LS7 engine and its intended use. This means you're getting optimized performance and durability tailored to your setup. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for details on proper fitment and assembly.
