What specific engine dimensions do these pistons fit?

These JE Pistons are designed for a 4.130 inch bore. They feature a flat top design with a -2.00 cc volume, a 1.115 inch compression distance, and use a 0.927 inch wrist pin.

Are these pistons suitable for all LS7 engine builds?

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

What does the 'FT' in the product name stand for?

The 'FT' in JE Pistons' part naming typically indicates a 'Flat Top' piston design. This refers to the shape of the piston crown, which is flat and commonly used in naturally aspirated or forced induction engines where specific compression ratios are desired.

Product Details

This is a set of eight JE Pistons, specifically designed for LS7 engines. You get the pistons themselves, ready to be installed in your build. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, which gives them the high tensile strength needed for serious performance applications. If you're rebuilding a high-demand LS7 engine, these pistons are built to handle the stress and deliver consistent power.

JE Pistons uses their proprietary Forged Side Relief (FSR) forging design, which helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons might also include an accumulator groove. This groove helps manage combustion gas pressure, reducing ring flutter and improving the seal for more reliable power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

Because these pistons are designed specifically for the LS7 engine and its intended use, they offer an optimized combination of performance and durability. They are made 100% in the USA, from the forging process to the final machining. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-performance LS7 build, these JE Pistons are a solid choice for durability and proven performance.
