Wiseco RED Series Chevrolet Big Block 4.560in Bore 1.155in CH 15.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine, Wiseco's RED Series pistons are a solid option. These pistons are forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for demanding racing applications and engines with power adders. The Race Engineered Design (RED) philosophy behind these pistons means they're precision-machined to give you a competitive edge, whether you're on the drag strip or the circle track.

Wiseco has incorporated several features to ensure durability and performance. Horizontal slot oiling in the pin bores helps keep the wrist pins and small-end connecting rods properly lubricated, which is crucial for a long service life under stress. The dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. This set includes premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal for reliable power delivery.

This set is designed for a 4.560-inch bore with a 1.155-inch compression height and a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
