MAHLE 930202530 Forged Racing Piston Bore Compression Pistons - 4.030 10.5 1

The MAHLE 930202530 is a high-performance forged racing piston designed for 358 cubic inch small block Ford applications. Constructed from MAHLE's premium 4032 aluminum alloy, this piston delivers exceptional strength and thermal stability for demanding race conditions.

Key Specifications:

• Bore: 4.030 inches
• Stroke: 3.500 inches
• Compression Height: 1.550 inches
• Pin Diameter: 0.927 inches
• Connecting Rod Length: 5.700 inches
• Compression Ratio: 10.5:1
• Dome Volume: -4cc (dish)
• Weight: 405 grams
• Material: 4032 aluminum alloy

MAHLE's 4032 alloy provides superior wear resistance and reduced thermal expansion compared to standard hypereutectic pistons, making it ideal for high-RPM racing applications and forced induction builds. The precisely machined -4cc dish allows for accurate compression ratio tuning when paired with the appropriate cylinder head combustion chamber volume.

This forged piston is engineered to withstand extreme cylinder pressures while maintaining critical tolerances. The 0.927-inch wrist pin diameter ensures adequate strength for high-load conditions, while the optimized 405-gram weight helps reduce reciprocating mass for improved engine response.
