    Less Rotating Weight for More Horsepower!
    These crankshafts use the same space-age material as Scat's 9000 Series Stock Replacements yet are modified to be lighter. Pro Comp Lightweight Crankshafts utilize lightening holes and aero-wing counterweights to reduce weight and windage. They're an ideal, affordable option for increasing the cubic inches and horsepower of mild to moderate street or race engines.

    Features
  • 9000 cast steel construction
  • Straight shot oil holes
  • Stress-relieved and shot-peened
  • Precision ground, micropolished journals
  • Lightening holes in all rod throws to reduce mass
  • Aero-wing counterweights increase horsepower by decreasing windage



    Scat has been manufacturing and distributing crankshafts, connecting rods, and engine components for more than fifty years. The tradition continues to this day with a 42,000 sq/ft facility in Redondo Beach, California. Quality is the first step in all Scat products... skilled craftsmen, superior materials, innovation, and dedication create the absolute best parts for you.

  • 934020 is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Good luck getting a good crank If you’re looking for a low end cost crank, quality is a slight bit better than stock. Expect to spend double to get balanced. The first crank needed 240/40 heavy metal to balance! The add states, “May” need Mallory. Get a Molnar rotating Assembly if your looking for serious (400+) HP. Cheap parts need more machining than quality parts to hit spec.
