Mechman high output alternators · Authorized dealer
Full-size Titan owners tend to stack electrical gear: an aftermarket stereo, bed and rock lighting, a winch or a second battery. This page gathers the Mechman 400 amp billet units for 2004-2015 and 2017-2019 trucks with the 5.6L V8, so you can match a Nissan Titan high output alternator to the exact model year in your driveway.
The 5.6L Titan uses two different alternator designs depending on year. Trucks from 2004-2006 take one unit, while 2007-2015 trucks and the 2017-2019 generation take another. The 2007 model year is the transition point: some 2007 trucks are listed under a separate 5.6L engine entry and use the earlier alternator. If you own a 2007, pay close attention to the engine choices and confirm the match in the vehicle finder above before ordering.
Both listings are 400 amp billet Nissan Titan high output alternators. That output suits trucks running a competition audio system, a full set of off-road lights, or a camper and trailer setup that pulls current for hours.
Mechman high output alternators pair well with upgraded charge and ground wire, so see our amp wiring kits and batteries while you plan. The same two alternators appear on the Nissan Armada and Infiniti QX56 pages, which share this V8 platform, and the Nissan alternator collection covers every other model.
