Description

Piston Kit - 4.125" +0.020" - 11.0:1 CR - 114"/117" Bored to 120" - M8

Features

  • New skirt coating technology is applied to the entire thickness of the piston-to-wall clearance for a zero install clearance; coating then abrades in on start-up to hone for the perfect fit per cylinder
  • Hard anodized top ring groove eliminates micro welding of the ring to the groove; this maintains a flat and smooth surface for the best ring seal and top ring groove
  • Teflon based skirt coating eliminates piston rock for the best possible ring seal with no piston slap noise
  • Hard anodized crown to aid in heat deflection and to reduce corrosion from alcohol fuels
  • Flat Top 1.2 cc design with oversized valve pockets to accept 1.00 mm larger valves
  • Includes pistons, rings, pins and clips
  • Made in the USA
