JE Pistons 3.820 BUICK V6 8.75 Set of 6 Pistons

Starting with pistons forged from 2618 aluminum, JE Pistons builds these sets specifically for high-demand performance applications like your 1984-1987 Buick Regal. This material choice is key because it offers the high tensile strength needed when you're pushing an engine hard, whether that's on the drag strip or just for spirited street driving. These aren't just generic pistons; JE Pistons applies over 75 years of experience to engineer and machine each set right here in the USA, ensuring they're optimized for your specific engine and use.

You'll find JE Pistons' proprietary Forged Side Relief (FSR) design here, which helps reduce friction and save weight by using a narrower skirt and a shorter wrist pin. Depending on the exact application, you might also find an accumulator groove, which helps manage combustion gas pressure to improve ring seal and maintain consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation. This attention to detail means you're getting a well-built set of pistons designed for both durability and performance.

This set includes six pistons, each with a 3.820-inch bore, an inverted dome/dish design, and a 1.850-inch compression distance. They are designed to fit your Buick Regal directly. Please note that these pistons are not CARB approved and cannot be shipped to California.
