Wiseco K452X135 LS Professional Series Piston Kit 4.135" Bore -20cc Dish

The Wiseco K452X135 is a Professional Series forged piston kit designed for high-performance LS engine builds. This complete 8-piston kit features a 4.135-inch bore diameter with a 4.000-inch stroke and a -20cc dish piston crown design optimized for compression control and performance.

Key Features:

• Forged from high-grade 2618 aluminum alloy for superior strength and heat resistance
• ArmorGlide skirt coating reduces friction and promotes bore stability for optimal ring seal
• -20cc dish crown shape designed for optimal quench during compression/combustion cycle
• Precision-machined ring grooves with proper orifice volume for maximum ring seal and minimized blow-by
• Complex piston crown shapes promote maximum intake charge efficiency through cross-flow scavenging
• Engineered for high-performance and forced induction applications up to 1500+ horsepower
• Resistance to detonation and preignition for longer engine life

This Professional Series kit includes forged pistons, piston rings, and wrist pins. The advanced forging process features feature-aligned grain flow technology for exceptional durability under extreme conditions. Ideal for serious LS engine builds, racing applications, and turbocharged or supercharged setups requiring pistons that can handle increased pressures and temperatures.
