Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.040 - Set of 8

If you're building a high-performance Chevrolet LS engine for racing, whether it's for drag strips or circle tracks, you need components that can handle serious stress. Wiseco's RED Series forged pistons are designed specifically for these demanding applications. They are constructed from 2618 aluminum, a material chosen for its high tensile strength, which is essential when you're pushing an engine hard, especially with power adders like turbos or superchargers.

These pistons feature a Race Engineered Design (RED) that optimizes their structure for strength and weight. You'll find horizontal slot oiling in the pin bores, a detail that ensures your wrist pins and connecting rod small ends stay well-lubricated, which is critical for longevity in a race engine. Wiseco also includes an accumulator groove to help maintain a consistent ring seal, keeping combustion pressures where they belong and maximizing power output. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you don't have to source them separately.

This set is for an 8-cylinder engine with a 4.040-inch bore and a -4cc flat top dish. Remember, these pistons are not CARB approved and cannot be shipped to California. They are manufactured in the USA.
