Features

  • Updates stock 107", 114” or 117” motor to 124” or 128” when using 4.250” big bore cylinders
  • Valve pockets are designed to accept up to +4.00 mm oversized intake and exhaust valves
  • Type 3 hard-anodized crown offers corrosion resistance for alcohol-added fuels
  • Type 3 hard-anodized top ring groove eliminates micro-welding of ring to the groove and gives a hard-flat surface for ring to rotate on
  • OE-style round wire locks are easily installed
  • Heavy-duty wrist pins with true .9270” diameter to fit rods correctly
  • Line2Line AST skirt coating starts out with a near-zero wall clearance and through the break-in period hones the cylinders to produce the correct oil wedge, keeping the piston square to the cylinder for best ring seal and quiet operation
  • Kit includes pistons, rings, pins and locks
