Manley 615000C-4 Forged Pistons for Subaru Bore Compression Distance Dish - 92mm 1.285

The Manley 615000C-4 forged piston set is precision-engineered for high-performance Subaru applications requiring a 92mm bore diameter. These pistons feature a 1.285-inch compression distance (measured from piston pin centerline to deck) and a dish design that helps optimize compression ratios for forced induction setups.

Key Features:

• 92mm bore diameter for stroker and big-bore Subaru builds
• 1.285-inch compression distance for specific deck height configurations
• Dish piston design ideal for turbocharged applications
• Forged construction for superior strength and durability under high boost and power levels
• Precision-machined to exacting tolerances for proper ring seal and reduced friction
• Set of 4 pistons for complete boxer engine rebuild

Manley Performance pistons are manufactured using premium-grade aluminum alloy forgings and advanced CNC machining processes. The dish configuration provides valve relief while maintaining optimal quench characteristics for turbocharged and supercharged engines. These pistons are designed for serious performance builders seeking reliability at elevated power levels.
