JE Pistons 4.030 350 SBC 9.5 Set of 8 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their domestic engine components. This set of eight pistons is specifically made for a 350 Small Block Chevy (SBC) with a 4.030 inch bore and a 9.5:1 compression ratio. These aren't just off-the-shelf parts; they're engineered and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that demand a lot of performance and durability.

What sets these pistons apart is their advanced design features. The proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by using a reduced skirt width, and it saves additional weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce pressure from combustion gases. This reduces ring fluttering and improves ring seal, leading to more consistent power output. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise. These pistons are designed specifically for the 350 SBC engine and its intended use, aiming for optimized performance and durability.

This piston kit includes everything you need for an 8-cylinder engine, with a 4.030 inch bore, a -14.5 cc dish volume, and a 1.550 inch compression distance. 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 350 SBC, these pistons are a solid option backed by JE Pistons' proven track record in racing.
