JE Pistons 350SBC ULTRA LT GP Set of 8 Pistons

When you're building a serious performance engine, especially one that's going to see boost or nitrous, you need pistons that can handle the pressure. This JE Pistons Ultra Series set gives you eight forged pistons designed for the demands of high-horsepower builds. You get the pistons themselves, ready to be installed, along with high-strength wrist pins from Trend Performance to connect them to your connecting rods.

What sets these Ultra Series pistons apart is JE's proprietary Aligned Grain Flow forging process. This isn't just about making a strong piston; it's about directing the grain flow within the metal to maximize tensile strength where it's needed most, helping them withstand extreme cylinder pressures. On top of that, they come with custom-level features you'd normally only find in a fully custom setup. The thermal barrier crown coating reflects heat back into the combustion chamber, which helps keep piston temperatures down and can improve how efficiently the exhaust gases are scavenged. The skirt coating is there to reduce friction and noise, especially when the engine is cold, and the lateral gas ports help maintain a solid ring seal even under high RPM and boost conditions. These are built for serious power and made 100% in the USA.

This set is designed for a 4.035-inch bore with a flat-top design, and includes 0.927-inch pins. Keep in mind these are not CARB approved and cannot be shipped to California. For the best results, always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
