Wiseco Chevy SB RED Series Piston Set 4185in Bore 1125in 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. Wiseco's RED Series pistons are built for exactly that kind of demanding use. They're forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial when you're pushing an engine hard, especially with power adders.

These pistons feature a Race Engineered Design, meaning they're specifically shaped for performance. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and the small end of the connecting rod well-lubricated, helping them last longer under high loads. The dedicated forgings allow for an optimized, engine-specific strutted design that balances strength with a manageable weight. Plus, they come with an ArmorGlide skirt coating that works to reduce friction and noise while also cutting down on wear to the piston skirt and cylinder wall. Each set includes premium rings, so you don't have to hunt for compatible ones separately, and an accumulator groove helps maintain consistent ring seal for reliable power delivery.

This set is designed for a 4.185 inch bore with a 1.215 inch compression height and a 0.927 inch pin diameter. Remember, these pistons are manufactured in the USA and are not CARB approved, so they cannot be shipped to California.
