JE Pistons 502BBC OPEN CHAM DOM Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is designed for an 8-cylinder engine with a 4.610-inch bore, featuring an open chamber dome design. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to offer a solid combination of durability and performance for racing and high-output street use.

The proprietary Forged Side Relief (FSR) forging design is a notable feature, helping to minimize friction and power loss. This is achieved through a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to less ring flutter and a better ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This piston kit is specifically designed for each engine and its intended use, aiming for optimized performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine where strength and reliability are paramount, this set from JE Pistons is a well-built option.
