Wiseco RED Series Chevy LS 4.005in Bore 1.294in CH -15.00 CC Piston Set

This is a set of eight Wiseco RED Series forged pistons designed for Chevrolet LS engines. You get the pistons themselves, complete with premium rings already included, so you don't need to source those separately. These pistons are built using Wiseco's Race Engineered Design (RED) process, which means they're forged and machined in the USA from 2618 aluminum. This material choice is crucial for the high tensile strength needed in demanding performance racing and power adder applications.

Wiseco has incorporated several features to ensure these pistons perform well and last. The horizontal slot oiling in the pin bores keeps the wrist pin and the connecting rod's small end well-lubricated, which is vital for longevity under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. Additionally, an accumulator groove is included to help maintain consistent ring seal and power output. The pistons also feature an ArmorGlide skirt coating, which works to reduce friction and noise during operation, while also minimizing wear on the piston skirt and cylinder wall.

This set is specifically engineered for the Chevrolet LS platform, a cornerstone for performance builds from drag racing to circle track. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
