HRC Pro Series 4340 Crankshaft
Big Block Chevy 4.000" Stroke, 6.135" Rod

100% American Made! the use of the finest high purity 4340 aircraft quality alloy. Forged by the experts at American crankshaft forgings, These forgings are shipped to the leader in high performance crankshaft machining, Callies Performance Products.. All journals have .125" Tru-Form fillet radii. 1" Angalite lightening holes in all rod throws. Callies Perma-Toughs these cranks to a depth of .080". This produces a wear layer that remains intact even if reground .060" under (other cranks have a hardness depth as little as ,003"). Journals are micro-finished to 5 microns or better. The best forgings, the best machining, and Perma-Tough hardening just what you would expect from a quality part.

NOTE: Requires chamfered bearings.

The Signature Series Crankshaft is created from non-twist 4340 steel, it comes completely profiled and detailed to our racing specs. The Signature Series Crankshaft has proven to withstand applications well over 1500 horsepower. Making it the strongest crankshaft you will find for your engine. Many design features such as micro polished journals, gun frilled mains lightened rod journals, and windage reducing counterweight profile making the Signature Series the best choice fore serious racers.

• All rod journals are frilled with either a 7/8" or 3/4" lightening hole to reduce the inertia weight of the crankshaft

• All journal radii are ground to .140"; roundness of each journal is .0001" or less

• Overall stroke is held to +/- .001"

• Pulsed plasma nitride treated for increased strength and durability

• Micro polished journals

• Proven to withstand over 1500 horsepower applications

Voodoo Series Big Block Chevy Crankshafts

The new line of Voodoo Crankshafts are engineered from 4340 forged non-twist steel that is known for its durability and strength in high heat applications. To add even further durability and consistency all Voodoo Cranks are nitride heat treated with micro polished journals . Furthermore by inserting lightning holes into the hod journals, the crankshaft inertia becomes lighter for faster rotation.

• Created from 4340 forged non-twist steel for durability and strength in high heat applications

• Lightening holes in the hod journals cause the crankshaft inertia to weigh less for faster rotation

• Nitride heat treated with micro polished journals
