Review on Reliable Alternator Replacement for Ford F Series Truck 4.6L/5.4L (97-02), Expedition - 321-1772, 334-2274, F75U-10300-CA/CB by Michael Bryan

No not OEM but for the price. I can't be wrong! Today, January 5, 2020, it was delivered and installed an hour later. Worked like a charm in an 18 year old truck. Fired up for the first time! Everything you need for DIY: an 8mm socket for disconnecting the negative (-) battery post, as well as the same socket for removing/loosening the hose clamp screws on the intake manifold at both ends (2 pcs). 10mm socket to remove the engine cover (3pcs), one on the passenger side, 2 on the driver side, a positive wire connector on top of the alternator and finally (3pcs) alternator bolts, 1 on top and 2 further down the bottom. 1/2" drive disconnect for loosening belt/tensioner. A small flathead screwdriver for removing connectors if you have big hands like mine. Total 30 minutes from start to finish with cleaning. 2002 Ford F150 4.6L v8. Oh yeah I did used a 1/4" drive kit and a Milwaukee M12 1/4" ratchet to complete the install. Also used a Gearwrench timing belt tool. Worth the money if you do it. a lot, especially for family and friends
