Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.125 - Set of 8

When you're building a performance Chevrolet LS engine, you need parts that can handle the stress. This set of eight Wiseco RED Series pistons is built for just that. You get the pistons themselves, each with a -4cc flat top dish, designed to work with a 4.125 inch bore. They also include a 1.294 inch compression height and a 0.927 inch pin diameter, fitting many popular LS applications.

Wiseco makes these pistons from 2618 aluminum, a well-known material for its strength in high-performance and racing engines, especially those with power adders like turbos or superchargers. To help them last and perform, they feature horizontal slot oiling in the pin bores for consistent wrist pin lubrication, and an accumulator groove to help maintain a good ring seal. The dedicated forgings allow for a strong yet lightweight design, and the ArmorGlide skirt coating helps reduce friction and noise while also cutting down on wear. Plus, this set comes complete with premium rings, so you won't have to hunt for those separately.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious LS builds, these are a solid option to consider.
