StacyRacing Posted February 9, 2013 Report Share Posted February 9, 2013 Here are some weights on the cranks questioned, the Stock crank is 54lbs, the SCAT 9000 Series Cast Crank is approximately 53lbs & the SCAT 4340 is 48-49lbs. The 4340 is not legal because it is too light. The stock crank is preferred. The SCAT 9000 Series Cast Crank is designed as a stock replacement and weighs real close to stock and will be accepted as legal. Make sure if you order the SCAT 9000 crank, it is the cast crank designed for stock replacement. Only factory balancing and casting marks allowed.
