Product Details

The Speedmaster PCE305.1123 forged piston set is engineered for Chevy LS2 engines with a 4.000" bore diameter. These high-performance flat top pistons feature a 1.065" compression height and .927" wrist pin diameter, designed to deliver reliable power in naturally aspirated and moderate nitrous applications.

Key Features:

  • Constructed from premium 4032 aluminum alloy for superior strength and durability
  • Flat top design optimizes combustion efficiency and compression ratio
  • Up to 20% lighter than traditional forged pistons, reducing reciprocating mass
  • Advanced forging process eliminates stress concentrations for enhanced reliability
  • Tighter piston-to-wall clearance for quieter operation and reduced blow-by
  • 4.000" bore diameter compatible with LS2 engine blocks
  • 1.065" compression height and .927" wrist pin diameter

These forged pistons provide an excellent balance of strength, weight savings, and thermal characteristics, making them ideal for street performance and racing applications. The 4032 alloy composition offers excellent wear resistance while maintaining tighter tolerances than hypereutectic pistons.
