  Wiseco Pistons - Chevy
18° & 23° 400 Dome
Included: Pistons, Pins & Spirolox (no rings)

This series is a favorite amongst engine builders. Some have solid domes allowing engine builders to dial in the compression ratio. Gram eights are very light due to the slipper skirt design.

The new 400 Dome Series parts are the best available. Contoured domes and other special features, along with a dedicated forging, ensures more then adequate thickness for the highest horsepower.

All Pistons Feature:
  • Radiused Valve Pockets
  • Skirt design allows for as little as .004" clearance with excellent wear properties.
  • Anti Detonation Grooves with the added benefit of keeping the top ring groove free of carbon
  • Pressure groove for enhanced ring seal.
  • Features Chrome Moly Pins and Spirolox
  • STD Tension Rings: 1/16, 1/16, 3/16
