Product Details

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for the 350 Small Block Chevrolet (SBC) engine, featuring a 4.035-inch bore and a flat-top design with a -4.0 cc dish. The 1.250-inch compression distance and 0.927-inch pin diameter are key dimensions for proper engine assembly and valve clearance. This kit includes eight pistons, ensuring you have everything needed for a complete engine rebuild.

JE Pistons brings over 75 years of experience to their forged piston designs, and these ULTRA LT GP pistons are no exception. They incorporate a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also contributes to weight savings, especially when paired with the shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which can improve ring flutter and enhance ring seal for more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

Every component in this set is engineered, forged, and machined 100% in the USA, ensuring a high level of quality control and supporting domestic manufacturing. This commitment to domestic production, combined with the advanced design features, makes these pistons a solid choice for builders seeking durability and performance. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
