Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.035 - Set of 8

These Wiseco RED Series pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for the demands of performance racing and boosted applications. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge. They are made in the USA, ensuring a high standard of manufacturing.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pins and the small end of the connecting rods properly lubricated. This is crucial for ensuring these high-stress components last a long time. The pistons also feature dedicated forgings with a strutted design, which Wiseco engineers to maximize strength while keeping the weight down. To further reduce friction and wear, each piston is treated with an ArmorGlide skirt coating, which also helps quiet down operation. An accumulator groove is included to help maintain consistent ring seal, which is key for consistent power delivery.

This set includes premium rings, so you won't need to source those separately. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for Chevrolet LS engines with a 4.035 inch bore.
