Wiseco K0434B135 Chevy LSx Stroker Forged Piston Kit Max Dome +0.135 Over

The Wiseco K0434B135 is a forged performance piston kit designed for Chevy LSx stroker engine builds. Engineered for high-compression, high-horsepower applications, this Max Dome kit delivers the strength and precision tolerances demanded by serious street and competition builds. Each piston is CNC-machined from aircraft-grade 2618 alloy forgings, providing superior strength and thermal resistance over cast or hypereutectic alternatives.

Key Features:

• Max Dome design — optimized dome profile for elevated compression ratios ideal for naturally aspirated performance builds
• +0.135" overbore — precision-sized for use with bored and honed LSx cylinder blocks
• 2618 forged aluminum alloy construction — exceptional strength-to-weight ratio with excellent fatigue resistance
• CNC-machined to tight tolerances — ensures consistent ring seal and proper piston-to-wall clearance
• Full floating wrist pin design — reduces side loading on piston pin bore for improved longevity
• Gas-ported ring lands (where applicable) — improves ring seal and reduces blowby under high cylinder pressure
• Includes pistons, wrist pins, locks, and rings — complete kit for easy assembly

Wiseco's LSx stroker piston kits are a trusted choice among professional engine builders seeking reliable power gains. The K0434B135 is built to handle the demands of forced induction, nitrous, or high-revving naturally aspirated LSx applications, making it an ideal foundation for any serious stroker project.
