Wiseco K0452XS Professional Series Forged Piston Set Chevy LT1 Gen V -15cc Dish 1.105 CH

The Wiseco K0452XS is a Professional Series forged piston set engineered specifically for the GM Gen V LT1 6.2L direct-injected engine. Featuring a -15cc dish crown and 1.105-inch compression height, this set is purpose-built for forced induction builds requiring a lower compression ratio, delivering the strength and precision demanded by serious racers and engine builders.

Key Features:

• 4.125 in. bore diameter with 1.105 in. compression height and 0.927 in. pin diameter
• -15cc dish crown engineered for the LT1's direct injection bowl geometry — maintains factory DI injector spray angle and fuel vaporization characteristics
• Forged 2618 aluminum alloy construction for superior tensile strength under high-boost and high-heat conditions
• ArmorGlide® skirt coating provides seizure resistance, reduced friction, and quieter piston operation
• ArmorPlating™ thermal barrier on the crown for added heat protection in forced induction applications
• 0.200-inch wall wrist pin with Spirolox® retainers included
• Anti-detonation and pressure seal grooves for enhanced ring seal integrity
• Premium GFX ring set included — 1.2mm top, 1.2mm second, 3.0mm oil control rings
• Strutted piston design for optimal strength-to-weight balance

Wiseco's Gen V LT1 piston forgings use a dedicated design that preserves the factory DI bowl shape and LT-specific valve reliefs, leveraging GM's original engineering investment while adding race-grade materials and coatings. The K0452XS is ideally suited for supercharged or turbocharged LT1 builds where a reduced compression ratio is critical for reliability and power output.
