Product Details

The Wiseco 6497B6 is a Professional Series forged racing piston built for serious engine builders demanding no-compromise performance. Part of Wiseco's race-proven Quick 8 Series, this individual/replacement piston is forged from 2618 aluminum alloy for superior tensile strength and thermal stability under extreme load. It features an 18-degree solid dome (+15.6cc) engineered for optimal flame travel and compression ratio consistency across a wide range of big-block builds. The piston is compatible with naturally aspirated and nitrous applications and is designed to fit a 9.750-inch deck height.

Key Features:

  • 2618 Alloy Forging: High-strength aluminum alloy provides improved tensile strength, heat resistance, and durability compared to 4032 alloy, making it ideal for high-boost and high-RPM race engines
  • Gas Ported Crown: Vertical gas ports allow pressurized combustion gases to reach behind the top ring, pressing it firmly against the cylinder wall for superior ring seal and reduced blow-by
  • 18-Degree Solid Dome: Universally engineered dome profile promotes proper flame travel and works with a broad range of popular 18-degree big-block cylinder head configurations
  • Strutted Skirt Forging: Internal strut design prevents the skirt cracking common with slab or full-round forgings under severe race conditions
  • ArmorGlide® Skirt Coating: Wiseco's proprietary anti-friction coating reduces piston-to-wall friction, allows tighter bore clearances, minimizes piston rock noise, and improves wear resistance
  • Precision Ring Grooves: Machined to exact tolerances with calculated groove root diameters and axial widths for maximum ring seal, minimal blow-by, and reduced oil consumption
  • Engineered Valve Pockets: Deep, precisely machined valve pockets accommodate oversized valves and high-lift camshafts while promoting maximum intake charge flow
  • Includes Wrist Pin: Ships with Wiseco pin S462 — rings sold separately
  • Recommended Ring Set: W77008-4560-5

Wiseco's Professional Series pistons are engineered, forged, and machined in the USA at their facility in Mentor, Ohio, using ISO-certified processes and advanced grain-flow forging technology. Built for heavy to severe-duty race applications, the 6497B6 delivers custom-level performance straight from the shelf — sold individually as a replacement piston.
