Mechman high output alternators · Authorized dealer
Trail-built Xterras collect accessories fast: light bars, a 12-volt fridge, an air compressor, maybe a winch. The Nissan Xterra high output alternator listed here is a 400 amp Mechman billet unit for 2005-2015 models with the 4.0L V6, sized to keep the battery topped up at idle on the trail and between camp stops.
The second-generation Xterra became a favorite base for overland and off-road builds because it is compact, simple and easy to modify. Those builds rarely stay light on electrical load. Auxiliary lighting, a dual battery setup, radios, a dash cam and a fridge running all night add up, and a long winch pull can drain a battery in minutes. Mechman high output alternators are made to restore that charge quickly, even at the low engine speeds common on slow technical trails.
This page lists one unit: a 400 amp billet Nissan Xterra high output alternator for the 2005-2015 4.0L. Use the vehicle finder above to confirm your year and engine before ordering.
A 400 amp alternator needs a charge wire and grounds to match, so plan on a big three upgrade with an amp wiring kit, and consider a deep cycle unit from our battery collection for camp loads. The same alternator is also listed for the Suzuki Equator and the Nissan Titan XD. For every other Nissan fitment, visit the Nissan alternator page.
