Wiseco K0433B1 Chevy LSX Stroker Max Dome Forged Piston Kit

The Wiseco K0433B1 is a Professional Series Chevy LSX Stroker Max Dome forged piston kit engineered for high-compression, stroker-style engine builds. Designed specifically for the GM LS/LSX platform, this kit delivers the precision and durability required for heavy to severe duty race applications where off-the-shelf pistons simply won't hold up.

Wiseco's Professional Series pistons are manufactured entirely in the USA from 2618 forged aluminum alloy, a material renowned for its superior tensile strength and thermal resilience under extreme racing conditions. The max dome crown profile is purpose-built for stroker configurations demanding elevated compression ratios.

Key Features:

• 2618 forged aluminum construction — superior tensile strength and fatigue resistance versus cast pistons
• ArmorGlide skirt coating — reduces friction, resists seizure, and enables quieter operation
• Fully machined crown with max dome profile optimized for LSX stroker builds
• Precision ring grooves with anti-detonation groove and enhanced ring seal geometry
• Forced pin oiling for improved wrist pin and small-end bearing lubrication
• 1.110 in. compression height — engineered for stroker crankshaft applications
• Engineered, forged, and machined in Mentor, Ohio, USA
• Includes premium piston rings, wrist pins, and circlips

Wiseco's Professional Series sets the benchmark for no-compromise racing pistons. Whether building a naturally aspirated high-compression LSX or a forced-induction stroker, the K0433B1 delivers the precision, strength, and consistency that championship-winning engine builders demand.
