Two Generations, Two Alternator Families

The 5.4L and 3.5L Expeditions use different alternator series, so start with the vehicle finder above the products and enter your year and engine. The 2006-2010 5.4L uses a V-mount series offered at 240 and 370 amps. The 2015-2021 3.5L uses a later series with 320 and 370 amp options. One of these Mechman high output alternators is billet, and finishes include black and natural.

Towing and Overland Loads

An electric trailer brake controller, trailer lights and a charge line to the camper battery all draw from the SUV while you tow. Add a 12V fridge, auxiliary lighting, rear-seat screens and stronger audio, and the demand stacks up on long grades at low speed. A Ford Expedition high output alternator keeps the trailer battery charging and the cabin powered. On the 5.4L, choose 240 amps for towing and family electronics or 370 amps for a full overland build; on the 3.5L, 320 amps covers a fridge and camp setup while 370 amps adds more room.

Shoppers comparing the luxury twin can see the Lincoln Navigator alternators, which list the same units. Heavy loads call for our amp wiring kits, and every Ford fitment is on the Ford alternators page.
