Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.045 - Set of 8

Starting with a 2618 aluminum forging, these Wiseco pistons are built for the demands of high-performance Chevrolet LS engines. The RED? series, or Race Engineered Design, means they're crafted with precision features to give you an edge, whether you're on the drag strip or the circle track. They're forged and machined right here in the USA, ensuring you get the strength needed for serious racing and power adder applications.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pins and small-end of the connecting rods properly lubricated. This is crucial for making sure these parts last under heavy use. Wiseco also uses dedicated forgings for each specific engine, allowing them to create a strutted design that maximizes strength while keeping the weight down. Plus, each set comes with premium rings already included, so you don't have to hunt for those separately. There's also an accumulator groove designed to help maintain consistent ring seal, which is key for keeping power where it belongs.

These pistons also feature an ArmorGlide? skirt coating. This isn't just for show; it's there to reduce friction and noise during operation, and it also helps cut down on wear on the piston skirts and cylinder walls. This combination of advanced materials and thoughtful design makes them a solid choice for anyone rebuilding or upgrading their LS engine for performance use.
