Wiseco K0450X05 Gen V LT1 Forged Piston Kit 4.070 Bore -2cc Dome 1.299 CH

The Wiseco K0450X05 is a forged performance piston kit engineered specifically for the GM Gen V LT1 6.2-liter engine platform. Featuring a 4.070-inch bore, 3.622-inch stroke compatibility, -2cc dome crown design, and a 1.299-inch compression height, this kit is purpose-built for builders working with stock connecting rods on direct-injected LT1 applications.

Key Specifications:

• Bore Diameter: 4.070 in.
• Stroke: 3.622 in. (stock stroke)
• Compression Height: 1.299 in.
• Crown Volume: -2cc Dome
• Pin Type: .180" wall pins with wire locks
• Rod Compatibility: Designed for use with stock connecting rods

Key Features:

• ArmorGlide Skirt Coating: A proprietary high-tech lubricant applied to the piston skirt that reduces friction, allows tighter piston-to-wall fitment than uncoated pistons, improves ring seal, and minimizes piston rock noise
• Direct Injection Crown Design: Crown geometry is specifically engineered to accommodate the LT1's high-pressure direct fuel injection system, replicating and improving upon the OEM dome profile
• Forged 2618 Aluminum Construction: Machined from high-strength 2618 aluminum alloy for superior tensile strength and durability under high-performance and forced induction conditions
• Dedicated Forgings: Features specially designed valve pockets, optimized skirt profiles, and precision-machined ring grooves tailored to the Gen V LT architecture
• Made in the USA: Engineered, forged, and machined at Wiseco's Mentor, Ohio manufacturing facility

This piston set is sold as a complete kit of 8 pistons and includes .180" wall wrist pins and wire locks. The -2cc dome crown makes this an ideal choice for high-compression naturally aspirated builds or as a foundation for boosted LT1 applications. Wiseco's GNX ring package is included, featuring a gas nitrided top ring, Napier-style second ring, and a stainless steel three-piece oil ring set.
