Wiseco 60009B110 Quick 16 Pro Series Gas Ported Forged Piston 4.610 Bore Big Block Chevy

The Wiseco 60009B110 is a Professional Series Quick 16 forged piston engineered for high-output Big Block Chevrolet drag race and performance engines. Designed with direct input from leading engine builders and Pro Stock technology, this single replacement piston is purpose-built for big-valve, big cubic inch Sportsman-class engines running stroked combinations with a 9.750 deck height and a 4.610-inch bore.

Forged from 2618 high-strength aluminum alloy and built on a strutted-style forging, the Quick 16 delivers race-ready durability while resisting the cracking commonly associated with slab or full-round forgings. The dome profile is engineered to maintain proper flame travel and support compression ratios up to 14.5:1, making it equally capable on naturally aspirated, nitrous, or exotic fuel combinations.

Key Features:

• Vertical Gas Ports: Pressurized combustion gases feed directly behind the top ring, pressing it firmly against the cylinder wall for superior sealing — more efficient than conventional lateral gas ports
• ArmorGlide Skirt Coating: Anti-friction coating reduces piston-to-bore friction, allows tighter piston-to-wall fitment, minimizes piston rock noise, and improves wear resistance
• 2618 High-Strength Alloy: Premium high-temperature aluminum alloy forging optimized for race use and power adders
• Strutted Skirt Forging: Reduces cracking risk versus slab or full-round designs while keeping piston weight in check
• Anti-Detonation Grooves: 15 Pro Stock-style pressure seal grooves protect against detonation and promote ring seal
• Reinforced Deck: Heavy-duty crown construction supports high compression and forced induction applications
• Tool Steel Wrist Pin Included (S462): 0.180-inch wall thickness limits flex and maximizes power transfer
• Profiled Dome: 50cc dome design fits conventional Big Block Chevy cylinder heads from today's leading manufacturers
• Fits 9.750 Deck Height — ideal for stroked BBC combinations in the 572–633+ cubic inch range
