Wiseco RED0081X185 Redline Forged Piston -15cc Dish 4.185 Bore Chevrolet

The Wiseco RED0081X185 is a high-performance forged aluminum piston from Wiseco's Redline series, engineered for Chevrolet V8 engine applications. Featuring a -15cc dish design, a 4.185-inch bore diameter, and a 1.294-inch compression height, this piston is purpose-built for high-output street and racing builds demanding superior strength and dimensional precision.

Wiseco forged pistons are manufactured from aerospace-grade aluminum alloy using a high-pressure forging process that produces a denser, stronger grain structure compared to cast pistons. The result is a piston that withstands extreme cylinder pressures, elevated temperatures, and the rigors of forced induction and high-RPM operation.

Key Features:

• -15cc Dish Design — Reduces compression ratio for compatibility with forced induction, high-compression pump gas, or nitrous applications
• 4.185" Bore Diameter — Sized for overbore Chevrolet V8 applications
• 1.294" Compression Height — Precision-machined for accurate deck height and rod/stroke geometry
• Forged Aluminum Construction — High-density forging delivers exceptional strength-to-weight ratio
• Wiseco Redline Series — Designed for domestic V8 performance and race engine builds
• Precision CNC-machined for tight tolerances and consistent ring seal
• Compatible with standard Wiseco wrist pins and ring sets (sold separately)

The Wiseco RED0081X185 is an ideal choice for engine builders constructing high-performance or competition-grade Chevrolet V8 powerplants where reliable, repeatable piston specs are critical to a successful build.
