Wiseco Chevy SB RED Series Piston Set 4020in Bore 1425in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevy Small Block engines. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge, whether you're on the drag strip or the circle track. This set is designed for a 4.020-inch bore, with a 1.425-inch compression height and a 0.927-inch wrist pin diameter.

Wiseco incorporates several thoughtful features to ensure longevity and performance. Horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end well-lubricated, which is crucial for extended service life under stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove designed to help maintain consistent ring seal and power delivery. Plus, each set comes complete with premium rings, so you don't have to hunt for compatible parts separately.

To further reduce friction and noise, these pistons feature an ArmorGlide skirt coating. This not only helps the engine run smoother but also reduces wear on the piston skirt and cylinder walls over time. This set includes eight pistons, ready to be installed in your performance build.
