What is included in this piston set?

This set includes eight JE Pistons BBC INV DOME pistons. It is designed for a 4.500 inch bore and comes with 0.990 inch wrist pins. Other components like rings are typically sold separately.

What makes the Forged Side Relief (FSR) design beneficial?

The FSR design minimizes friction and power loss by reducing the piston skirt width and using a shorter wrist pin. This also helps to save weight on the rotating assembly.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is a set of eight JE Pistons BBC INV DOME pistons, designed for a 4.500 inch bore. You get the pistons themselves, ready to be installed in your big block Chevrolet engine. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of demand and high performance use.

JE Pistons has been making performance pistons for over 75 years, and they've put that experience into this set. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons might also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power. Some applications also come with a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

These pistons are made 100% in the USA and are specifically designed for each engine and use application to give you the best combination of performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
