Wiseco K444X65 Chevy LS Professional Series Forged Piston Set -11cc Reverse Dome 4.065 in. Bore

The Wiseco K444X65 is a Professional Series forged piston set designed for Chevrolet LS engines, featuring a 4.065-inch bore, 1.300-inch compression height, 0.927-inch pin diameter, and a -11cc reverse dome (R/dome) head design.

Key Features:

• Forged from 2618 aluminum — engineered, forged, and machined in the USA for superior tensile strength and thermal resilience under heavy-duty race conditions
• -11cc reverse dome crown — optimized combustion chamber geometry for targeted compression tuning in LS platform builds
• 4.065 in. bore with a 1.300 in. compression height and 0.927 in. pin diameter
• ArmorGlide® skirt coating — reduces friction, improves wear resistance, and allows tighter bore fitment compared to uncoated pistons for maximum power transfer
• Gas nitrided premium rings included — enhances ring durability and sealing performance in high-horsepower applications
• Reluctor ring clearance — accommodates the reluctor ring on stroker cranks without requiring notching of the pin bosses
• Compatible with Chevrolet LS series engine blocks

Wiseco's Professional Series represents a no-compromise approach to piston technology, delivering custom-level performance and durability features straight out of the box. The K444X65 is engineered for heavy to severe-duty race builds where reliability at the limit is non-negotiable.
