Why Forged Pistons Matter:

• 100% forged in-house construction for superior strength and durability
• Condensed grain structure aligned to part features for maximum mechanical properties
• Enhanced resistance to impact and fatigue compared to cast pistons
• Optimized strength-to-weight ratio for maximum performance
• Will not fail catastrophically like brittle cast pistons when material limits are exceeded

• Forged piston with 67.00mm bore diameter
• Piston rings
• Wrist pin
• Circlips
• Top-end gasket set
