The Eagle forged 4140 crankshaft for Chevrolet LS engines is a competition-grade crank with a 3.622" stroke and an integrated 24-tooth reluctor. Its non-twist forging and .125" fillet radii increase strength, while nitrided and micropolished journals improve surface durability. Intended for competition use, the crank requires chamfered or narrowed bearings and includes the 24-tooth reluctor for LS ignition timing.
