Keith Black Pistons 3420H-5MM Hypereutectic Piston Set 3.4L GM V6

The Keith Black Performance Pistons 3420H-5MM is a complete hypereutectic piston set designed specifically for 3.4L GM V6 engines from 1993-1995 model years. This premium piston set delivers enhanced durability and performance over stock cast pistons while maintaining excellent street reliability.

Key Features:

• Hypereutectic aluminum construction for superior strength and reduced thermal expansion
• 5mm oversized bore diameter for rebuilding worn cylinders
• Engineered specifically for 3.4L GM V6 applications (1993-1995)
• Complete piston set included for all cylinders
• Improved heat dissipation compared to standard cast pistons
• Tighter piston-to-wall clearances for reduced oil consumption

Keith Black hypereutectic pistons are manufactured using advanced metallurgy that incorporates higher silicon content, resulting in pistons that are harder, stronger, and more wear-resistant than conventional cast pistons. This makes them an ideal choice for stock replacement or mild performance builds where reliability and longevity are priorities.
