Included: Pistons, Pins & Spirolox, Skirt Coatings
Rings: 1/16, 1/16, 3mm rings

NOTES - Please Read:

As the leader in LS-1 forged pistons, Wiseco pulled out all the stops when designing this series. They are designed to accommodate the reluctor ring on stroker cranks without having to notch the pin bosses. Offset pins like o.e. and skirt shapes specifically designed for street applications make these the best available. They have been tested successfully in the highest horsepower applications.

All Pistons Feature:
  • NEW Coated skirts for LS Series Pistons. Much higher adherence factor then other moly coatings.
  • 2618 Alloy: Will not shatter like hypereutectic, or cast pistons.
  • Strutted skirt design is the strongest and specially designed to run at as little as .004" clearance, with excellent skirt wear and minimal noise or rock.
  • Radius valve pockets for detonation resistance and increased flow around valves.
  • Anti Detonation Grooves with the added benefit of keeping the top ring groove free of carbon
  • 3mm oil rings for better oil control and reduced friction for more horsepower
  • Pressure groove for enhanced ring seal
  • Features Chrome Moly pins and spiralox, tool steel pins optional
  • Race Ready domes don't require deburring by the engine builder

*K392, K393,K394,K395,K396,K397,K398, and K399 parts have been upgraded to the 3mm oil ring, LS combo pockets, and Race Ready dome
preparation. Vol. changes have occurred on Flat tops. Some piston weights have changed.
