JE Pistons Chevrolet Small Block 4.125in Bore 1.062in CH -4.50 CC Piston Kit - Set Of 8

This kit includes a complete set of eight forged pistons for your Chevrolet Small Block engine. These pistons feature a 4.125 inch bore and a -4.50cc dome volume, designed to work with specific engine builds for optimized performance and durability. They are made from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines operating under demanding conditions.

JE Pistons brings over 75 years of experience to these domestic application pistons. Each piston is forged and machined entirely in the USA, ensuring a high standard of manufacturing. The proprietary Forged Side Relief (FSR) design is notable for minimizing friction and power loss by using a reduced skirt width and a shorter wrist pin, which also helps save weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

These pistons are specifically designed for each engine and use application, aiming for the best combination of performance and durability. They are proven in various racing environments, from dirt tracks to drag strips. Please note that this kit is not CARB approved and cannot be shipped to California. It is important to consult the manufacturer's installation instructions for proper fitment and assembly details.
