Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.070 - Set of 8

If you're building a high-performance Chevrolet LS engine, Wiseco's RED Series forged pistons are a solid choice. These pistons are specifically designed for demanding applications like drag racing and circle track, where strength and durability are paramount. They're made in the USA from 2618 aluminum, a material known for its high tensile strength, which is crucial for handling the stresses of performance engines, especially those with power adders.

Wiseco has put a lot of thought into the details with these pistons. You'll find horizontal slot oiling in the pin bores, which helps keep the wrist pins and connecting rod small ends properly lubricated, contributing to a longer service life. The dedicated forgings allow for an optimized, engine-specific strutted design, meaning they achieve maximum strength while keeping weight down. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you won't have to hunt for those separately.

This particular set features a -4cc dish, a 1.294-inch compression height, and a 4.070-inch bore, making them suitable for many popular LS engine builds. An accumulator groove is also included to help maintain consistent ring seal and power output. Keep in mind these are not CARB approved and cannot be shipped to California.
