Wiseco Chevrolet LT1 -.4cc DI Dome 1.3260 X 4.065 - Set of 8

When you're rebuilding a high-performance Chevrolet LT1 engine, you need parts that can handle the stress. This set of eight Wiseco RED Series pistons is built for just that. They start with a dedicated forging from 2618 aluminum, chosen for its strength, and are then precisely machined right here in the USA. The Race Engineered Design (RED) process means these pistons are optimized for strength-to-weight, giving your engine a competitive edge whether it's on the drag strip or the circle track.

Wiseco engineers have included some smart features to help these pistons last. The horizontal slot oiling in the pin bores keeps the wrist pins and small-end of the connecting rods well-lubricated, which is crucial for durability under heavy use. You'll also find an accumulator groove, which helps maintain a consistent seal for the piston rings, ensuring you get every bit of power and a solid seal. Plus, each set comes complete with premium rings, so you don't have to hunt for compatible ones separately.

To further reduce friction and wear, these pistons feature an ArmorGlide skirt coating. This not only helps quiet things down but also cuts down on skirt and cylinder wear, contributing to a longer service life for your engine build. These are a solid option if you're looking for well-built, performance-oriented pistons for your LT1 project.
