Mechman high output alternators · Authorized dealer
Seating for seven or eight, a strong V8 and serious towing capacity make the Armada a go-to for families who pull boats and campers. This page carries the Mechman 400 amp billet units for 2005-2015 and 2017-2021 models with the 5.6L, so each Nissan Armada high output alternator lines up with a specific generation.
Every Armada on this page uses the 5.6L V8, but the alternator changes by year. The 2005-2006 models take one design, while 2007-2015 models and the redesigned 2017-2021 generation share a second. There is no 2016 entry in this listing. Select your year and engine in the vehicle finder above and the grid will show the right unit.
A loaded Armada can be running a trailer brake controller, charging a camper battery through the seven-pin, powering rear entertainment screens and keeping a cooler or fridge cold, all at once. Add aftermarket lighting or a sound system and the original alternator has little to spare. Mechman high output alternators are built for that kind of steady draw, and each Nissan Armada high output alternator here is a 400 amp billet unit.
Round out the upgrade with an amp wiring kit. The same alternators are listed for the related Nissan Titan and Infiniti QX56, and our Nissan alternators page covers the rest.
