As the premium line of cranks offered by Lunati, Signature Series Crankshafts are the strongest you will find for your engine. The specialized non-twist 4340 forged steel construction comes completely profiled and detailed to our racing specs. Many design features such as gun-drilled mains, lightened rod journals, micropolished journals and a windage reducing contoured wing counterweight profile make the Signature Series the best choice for serious racers.
  • All rod journals have drilled lightening holes to reduce the inertia weight of the crankshaft
  • All journal radiuses are ground to .125"; roundness of each journal is .0001" or less
  • Pulsed plasma nitride heat treated for increased strength and durability
  • Micropolished journals
NOTE: All Lunati crankshafts MUST use narrow or chamfered main and rod bearings.
