What specific engine dimensions do these pistons fit?

These pistons are designed for a 4.625-inch bore. They feature a 1.270-inch compression distance and a 0.990-inch pin diameter, with a -3.0 cc volume for the flat top.

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

The FSR design is intended to minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are any special coatings or grooves included with these pistons?

Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure and improve ring seal. A skirt coating may also be present to reduce friction and wear on the piston skirts and cylinder walls, potentially quieting operation.

Product Details

This is a set of eight JE Pistons, specifically designed for 454 BBC (Big Block Chevrolet) engines intended for heavy-duty or blown applications. You get eight forged pistons, each with a flat-top design, ready to be installed in a 4.625-inch bore. These pistons are crafted from 2618 aluminum, a material known for its high tensile strength, which is crucial for handling the intense pressures and heat found in high-performance racing engines.

JE Pistons brings over 75 years of experience to these components, and they are forged, engineered, and machined entirely in the USA. The design includes a proprietary Forged Side Relief (FSR) forging, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving the seal for consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set is engineered for optimized performance and durability in demanding racing environments, from dirt tracks to drag strips. Please note that these pistons are not CARB approved and cannot be shipped to California.
