Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.075in Bore - Set of 8

What you get in this kit are eight forged pistons designed for Chevrolet LS engines. These aren't just any pistons; they're part of Wiseco's RED (Race Engineered Design) series, built to handle the demands of high-performance racing and engines with power adders. They're made from 2618 aluminum, which is known for its tensile strength, crucial when you're pushing an engine hard, whether that's on the drag strip or the circle track.

Wiseco machines these pistons in the USA, and they've included some smart features to help them perform and last. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pins and the small end of the connecting rods well-lubricated – that's key for a long service life. The dedicated forgings mean they're shaped specifically for LS engines, balancing strength with a manageable weight. Plus, each set comes with premium rings, so you won't have to hunt for those separately. They also feature an accumulator groove to help maintain a consistent ring seal, which means consistent power delivery.

To further reduce friction and noise, these pistons have an ArmorGlide skirt coating. This not only helps things run smoother but also cuts down on wear to the piston skirts and the cylinder walls. It's a well-built set designed to give you a competitive edge when you need your engine to perform at its best.
