Product Details

The Keith Black KB266-STD hypereutectic piston set is engineered specifically for Harley-Davidson Evolution engines with 80 cubic inch (1340cc) displacement from 1984-1999. These high-performance pistons feature a dome design with -16.5cc volume, providing optimal compression characteristics for improved power and efficiency.

Key Specifications:

  • Displacement: 80 cubic inches (1340cc)
  • Dome Volume: -16.5cc
  • Rod Length: 7.440 inches
  • Application: Harley-Davidson Evolution engines 1984-1999
  • Construction: Hypereutectic aluminum alloy
  • Bore: Standard size

Keith Black hypereutectic pistons are manufactured from a high-silicon aluminum alloy that provides superior wear resistance and thermal stability compared to standard cast pistons. The dome design helps optimize combustion chamber geometry for enhanced performance, while the hypereutectic material allows tighter piston-to-wall clearances for reduced noise and improved ring seal.

Sold as a complete piston set for proper engine balance and performance.

Great prices and quick delivery. Email response on purchase and follow up very good.

Super pricing, fast shipments, good selection they have it all.

So far its been fast and easy. I only hope the box comes undamaged. It looks like a nice box. Arrived with a little cardboard damage from UPS. The toolbox had some minor dents that I successfully pounded out. Was no fault of yours. Thanks.

I had a hard time locating all the correct oxygen sensors for my vehicle (requires 4).
