LS Series Wiseco 4.000 Stroke Flat Top Pistons (-3cc 4.070 Bore)


Model Number: K464x7

As the leader in LS-1 forged pistons, Wiseco pulled out all the stops when designing the LS Series. These pistons 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.

  • Skirt design allows for as little as .004″ clearance with excellent wear properties.
  • Radiused Valve pockets.
  • 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.
  • Wiseco designed the LS-1 Series to accommodate the reluctor ring on stroker cranks.
  • Includes Wiseco’s GFX piston rings
