Wiseco RED Series Chevy Small Block 400 4.135in Bore 1.550in CH -15.00 CC Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chevrolet Small Block 400 engines. Each piston features a 4.135-inch bore, a 1.550-inch compression height, and a -15.00cc dish volume. These pistons are part of Wiseco's RED (Race Engineered Design) series, built to handle the demands of performance racing and engines with power adders.

Crafted from 2618 aluminum in the USA, these pistons offer the tensile strength needed for competitive performance. They incorporate horizontal slot oiling in the pin bores to ensure optimal lubrication for the wrist pin and small end of the connecting rod, which is crucial for a long service life. The dedicated forgings allow for an engine-specific strutted design, maximizing the strength-to-weight ratio. Additionally, each set comes complete with premium rings, eliminating the need for separate sourcing, and features an accumulator groove to help maintain consistent ring seal and power output. The ArmorGlide skirt coating is applied to reduce operating friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

These pistons are intended for performance applications and are not CARB approved, meaning they cannot be shipped to California. For installation, it is recommended to consult the manufacturer's detailed specifications and torque requirements to ensure proper fitment and performance.
