KB Performance 120 in. Big Bore Super Duty Forged Piston Kit - KB542LCA.020
  • 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
  • Skirt coating eliminates piston rock for the best possible ring seal with no piston slap noise
  • Flat top 1.2cc design with oversized valve pockets to accept 1mm larger valves
  • Hard anodized crown to aid in heat deflection and to reduce corrosion from alcohol fuels
  • 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
  • Includes pistons, Hastings rings, pins and clips
  • Made in the U.S.A.
