Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.075 - Set of 8

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This RED Series piston set is built specifically for Chevrolet LS engines, offering the kind of durability and precision you need when you're pushing your engine hard, whether that's on the drag strip or the circle track. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them the tensile strength required for high-performance racing and boosted applications.

What sets these pistons apart is their Race Engineered Design, or RED, which means they're optimized for strength and weight. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is crucial for a long service life. They also feature an accumulator groove to help maintain a consistent ring seal and keep power levels steady. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirts and cylinder walls.

This set comes complete with premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding a performance LS engine, these pistons are a solid option designed to handle the demands of serious power.
