Wiseco RED Series Chevy LS 4.000in Bore 1.294in CH -15.00 CC Piston Set

If you're building a performance Chevy LS engine, this Wiseco RED Series piston set is a solid choice. These pistons are specifically made for the LS platform, featuring a 4.000-inch bore and a 1.294-inch compression height with a -15.00 CC dish. They're designed to handle the demands of racing and power adder applications, offering the strength and durability you need for serious performance.

Wiseco crafts these pistons from 2618 aluminum, a material known for its tensile strength, making them well-built for high-stress environments. They incorporate Race Engineered Design (RED) principles, which means they're optimized for specific engines to maximize strength while keeping weight down. You'll find horizontal slot oiling in the pin bores to ensure the wrist pin and connecting rod small end stay properly lubricated, which is crucial for long service life. Plus, each set comes complete with premium rings, so you don't have to source them separately.

To further reduce friction and wear, these pistons feature an ArmorGlide skirt coating. This coating not only helps quiet down operation but also minimizes skirt and cylinder wear. An accumulator groove is also included to help maintain consistent ring seal and power output. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
