Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.135 - Set of 8

These Wiseco pistons start with a -4cc flat top dish, a specific design choice that helps manage compression ratios in your Chevrolet LS engine build. They're forged from 2618 aluminum right here in the USA, a material chosen for its high tensile strength, which is exactly what you need when you're pushing the limits with performance racing or adding power adders like turbos or superchargers.

Wiseco's Race Engineered Design (RED) series means these pistons are built for serious performance. You'll find horizontal slot oiling in the pin bores, a detail that ensures your wrist pins and the small end of the connecting rods get consistent lubrication, which is crucial for keeping things running smoothly over the long haul. The dedicated forgings allow for an engine-specific strutted design, meaning they've optimized the strength-to-weight ratio for LS engines. Plus, the ArmorGlide skirt coating is there to cut down on friction and noise, while also reducing wear on the piston skirts and cylinder walls. This set comes complete with premium rings, so you won't have to hunt for those separately.

An accumulator groove is also included, which helps maintain a consistent seal for the piston rings, contributing to steady power delivery. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications where durability and precise machining are key.
