Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.005 - Set of 8

What you get in this kit are eight Wiseco forged pistons designed for Chevrolet LS engines. These are the RED Series pistons, featuring a flat top design with a -4cc volume and a 4.005-inch bore. They're built from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for demanding performance racing and applications where you're adding significant power.

Wiseco uses dedicated forgings for these pistons, allowing them to optimize the strutted design for maximum strength while keeping the weight down. You'll find horizontal slot oiling in the pin bores, which is a smart detail that ensures the wrist pin and the small end of the connecting rod stay well-lubricated, crucial for a long service life. They also come with an ArmorGlide skirt coating. This coating helps reduce friction and noise during operation, and it also cuts down on wear to both the piston skirt and the cylinder wall. Plus, each set includes premium rings, so you won't need to source those separately. An accumulator groove is also part of the design, helping to maintain consistent ring seal and keep power levels steady.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious LS engine builds, these pistons are a solid choice for their robust construction and thoughtful features aimed at performance and durability.
