Wiseco 6492B110 Quick 8 Series Forged Piston 2618 Alloy Gas Ported Solid Dome Individual

The Wiseco 6492B110 is a Professional Series Quick 8 forged piston engineered for serious Big Block Chevy race builds. Forged from 2618 aluminum alloy using Wiseco's ISO-certified facility, this piston features a next-generation strutted forging design that delivers exceptional strength while keeping weight in check. The solid dome is designed for 12–14 degree cylinder head configurations and fits a 9.750" deck height engine, making it well-suited for high-compression, high-RPM competition applications.

Gas porting is standard on this piston, working in conjunction with a lightweight .043" compression ring package to maximize ring seal on the power stroke while minimizing drag on intake, exhaust, and compression strokes. The 6492B110 is nitrous compatible and features 15 "Pro Stock" pressure seal grooves and reinforced deck construction to withstand extreme cylinder pressures. This is sold as an individual/replacement piston — ideal for replacing a single piston in an existing set.

Key Features:

• 2618 Alloy Forged Construction — Higher tensile strength and superior heat resistance compared to 4032 alloy; absorbs detonation events that would crack cast or lesser forged pistons
• Quick 8 Series Solid Dome — 12–14 degree dome profile with a 0.200" thick deck, allowing custom valve pocket machining or dome milling for flat-top conversion
• Gas Ported Design — Vertical gas ports channel combustion pressure behind the top ring for maximum ring-to-wall seal on the power stroke
• Nitrous Compatible — Profiled dome and reinforced construction engineered to handle nitrous oxide applications
• Strutted Skirt Forging — Lightweight strutted design resists the cracking common in slab or full-round forgings under high load
• ArmorGlide Skirt Coating — Wiseco's proprietary anti-friction coating reduces bore friction, allows tighter piston-to-wall fitment, improves ring seal, and minimizes piston rock noise
• Tool-Steel Wrist Pin Included — Pin S462 included; features 0.180" wall thickness to resist flexing at maximum power
• Precision Ring Grooves — Machined to exacting tolerances for optimum ring seal and minimal blow-by and oil consumption
• Valve Pocket Design — Machined pockets accommodate oversized valves and high-lift camshafts

Recommended Ring Set: W77008-4610-5 (sold separately). Included Wrist Pin: S462. This piston fits a 9.750" deck height block. Rings are sold separately.

Wiseco has built race-winning pistons for the world's most demanding motorsport venues — from Formula 1 and IRL IndyCar to NHRA Pro Stock and AMA Superbike — bringing that same engineering depth to every piston in the Quick 8 lineup.
