Eagle Jeep I6 4.0L/4.2L 4.060in Stroke Cast Crankshaft

Eagle is well-known for making strong internal engine components, and this cast crankshaft is a solid choice for your Jeep's 4.0L or 4.2L straight-six engine. It's a great alternative and an upgrade over the original equipment crankshaft, offering improved strength for your build. This crankshaft features a 4.060-inch stroke, giving you a bit more displacement and potential for power.

What really sets this crankshaft apart is its .092-inch fillet radii. This design detail significantly increases the strength of the crankshaft where it matters most, helping it withstand the stresses of regular driving. Even with these improved radii, you can still use standard OE replacement bearings, which simplifies the rebuild process. Eagle has designed this crankshaft for use in pump-gas, naturally-aspirated road cars that aren't intended for competition, making it a reliable choice for daily drivers and weekend cruisers looking for a well-built replacement.

When you're rebuilding the heart of your Jeep, choosing a well-built crankshaft is crucial. This Eagle cast crankshaft offers a practical upgrade with added strength and the convenience of using readily available bearings. It's a smart move for anyone looking to ensure the longevity and performance of their Jeep's engine.
