Track Smart™ 4340 American Crankshafts

1-Track-Smart™-4340-American-Crankshafts-HRC 353557TS2No inferior imports here! Only the finest quality premium grade 4340 aerospace chrome moly material American forgings are used. After close inspection, they are machined on the most advanced CNC machines in the industry. They are then nitrided and all surface journals are micro-polished to five microns or better. Number 1 and 4 rod throws have lightening holes. Large .125” radii on all journals (chamfered bearings required).

Track Smart™ 3 4340 Crankshafts

2-Track-Smart™-3-4340--Crankshafts-HRC H353756012TAll new computer designed premium 4340 steel forgings. Properly placed counterweights that not only improve balance but reduce bearing loads. The forgings are rough machined in a process that includes double stress relief operations that make these crankshafts dimensionally stable. Hardened with a deep nitride for superior wear resistance, ideal for abusive track environments. All rod journals are drilled and counterweights are profiled for piston clearance. Large .125” radii on all journals (chamfered bearings required). Consistent grind and polish, along with precise stroke and index. The new standard in performance crankshafts.

ProMax 4340 Crankshafts

3-ProMax-4340-Crankshafts-HRC 403860-6100% American Made! Starting with the finest high purity 4340 aircraft quality high nickel alloy. Many manufacturers state they use 4340, but very few use the same quality. There is a difference! Forged by the experts in American crankshaft forgings, Louisville forge in Kentucky (again, only a few can state this). These forgings have high quantities of nickel and chromium, which insures strength and long service life. These forgings are shipped to the leader in high performance crankshaft machining, Callies Performance Products. They are machined to the highest specifications, with roundness within 60 millionths and taper being held to within .0003” on all rod and main dimensions. All journals have .125” Tru-Form radii. 1” Angalite lightening holes in all rod throws. Callies ”Deep Case” hardening produces a wear layer that remains intact even if reground .010” 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 best hardening. Which crank will you run? Requires chamfered bearings.
