Wiseco Chevy SB RED Series Piston Set 4010in Bore 1250in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing, like drag or circle track, you need pistons that can handle the stress. This Wiseco RED Series piston set is built for those demanding applications. They're forged from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard or adding power adders.

Wiseco machines these pistons in the USA, using dedicated forgings that allow for an optimized, engine-specific strutted design. This approach maximizes strength while keeping the weight down. You'll also find horizontal slot oiling in the pin bores, which helps keep the wrist pin and small-end of the connecting rod properly lubricated for a longer service life. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, and it also cuts down on wear on both the piston skirt and the cylinder wall. This set comes complete with premium rings, so you don't have to source them separately, and an accumulator groove helps maintain consistent ring seal for reliable power.

This set is designed for a 4.010 inch bore, with a 1.250 inch compression height and a 0.927 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
