Wiseco K445X05 Professional Series Chevy LS Forged Piston Kit -15cc Dish 4.005 in. Bore

The Wiseco K445X05 is a Professional Series forged piston kit designed for Chevrolet LS series engines. This shelf-stock kit features a 4.005 in. bore, -15cc reverse dome dish, 1.110 in. compression height, and 0.927 in. wrist pin diameter, engineered to deliver race-level performance for serious engine builders.

Key Features:

• Forged 2618 aluminum construction — engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility for superior tensile strength in performance and power-adder applications
• ArmorGlide® skirt coating — reduces operating friction and noise while improving wear resistance and allowing tighter piston-to-wall fitment
• Reluctor ring clearance — accommodates the reluctor ring on stroker cranks without requiring pin boss notching
• OE-style offset wrist pins — skirt geometry specifically tuned for smooth, quiet street and performance operation
• Anti-detonation and pressure seal grooves — improves ring seal, reduces piston rock noise, and enhances combustion efficiency
• -15cc reverse dome dish — ideal for tuning compression ratios on LS platform builds

Wiseco Professional Series piston kits are no-expense-spared components built for heavy to severe-duty race and performance builds. The K445X05 has been successfully tested in high-horsepower applications and is a proven choice for LS engine builds ranging from street performance to forced induction.
