Product Description

The Wiseco K444X7 is a professional-series forged piston kit designed for GM LS V8 engines (Gen III/IV). With a 4.070" bore and a -11 cc dish crown, these pistons provide an optimized compression ratio suitable for naturally aspirated, boosted, or nitrous applications.

Constructed from 2618 forged aluminum with ArmorGlide® coating, these pistons offer excellent durability, reduced friction, and strong ring sealing. The strutted skirts and offset wrist pins provide stability and compatibility with stroker cranks without requiring pin boss modifications.

Included with the kit are floating wrist pins secured by Spirolox retainers and a full set of GFX rings (1.2 / 1.2 / 3.0 mm). Recommended for high-performance LS builds, these pistons deliver reliability, strength, and precision for engines producing up to extreme horsepower levels when paired with optional wrist pin upgrades.
