The Eagle cast crankshaft for Jeep/AMC 4.0L and 4.2L inline-six features a 4.060" stroke and .092" fillet radiuses to increase strength over OE units while remaining compatible with stock replacement bearings. Cast construction makes it a cost-conscious upgrade for pump‑gas, naturally aspirated road cars seeking reliable rotating assembly components.
