JE Pistons 400SBC ALLPRO/GB2000 Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this set of 8 pistons for 400 SBC engines. These aren't just off-the-shelf parts; they're engineered specifically for your engine and its intended use, aiming for the best balance of durability and performance. You'll find JE Pistons proving their worth in competition time and time again, from dirt tracks to drag strips.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand performance applications. They feature JE's proprietary Forged Side Relief (FSR) design. This design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve ring seal for consistent power. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise.

This set includes 8 pistons, each designed for a 4.140-inch bore with a 1.100-inch compression distance and a 0.927-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For installation, it's always best to refer to the manufacturer's detailed instructions to ensure proper fitment and performance.
