GMC Safari High Output Alternators

The GMC Safari is a quiet favorite for compact camper builds. It fits in a normal parking spot, yet it holds a bed, a 12 V fridge and a roof fan. Keeping the house battery charged on the drive is the alternator's job. This page lists every GMC Safari high output alternator Mechman offers for 1990-1993 and 1996-2005 4.3L vans.

Charging a House Battery on the Move

A small camper runs loads all night. The fridge cycles, the vent fan runs and phones charge. By morning the house battery needs a real recharge, and a short drive to the trailhead has to do it. A Safari high output alternator puts more current into that battery per mile, so you spend less time idling in a campground.

Which Years This Page Covers

The 4.3L Safari comes in two groups, 1990-1993 and 1996-2005, and each takes a different alternator family, so enter your year in the vehicle finder above. Those are the years we list. If your van falls outside them, ask us before ordering.

How Much Output a Camper Safari Needs

Mechman high output alternators for the Safari come in 170, 240, 250, 320, 370 and 400 Amp.

  • 170 Amp: a weekend setup with a fridge, lights and a fan on one auxiliary battery.
  • 240 or 250 Amp: a larger battery bank and a small inverter for a laptop or coffee maker.
  • 320 or 370 Amp: a full-time travel van with a big inverter and longer stays off grid.
  • 400 Amp: a large house bank you want to refill quickly on short drives.

Lithium house banks accept charge quickly, so many builders pair one with a higher output unit and a suitable charge controller. See our lithium batteries, and use heavy cable from our wiring kits to run charge current back to the bed area. Billet and standard cast housings are both offered. Billet is machined from solid aluminum, with finishes such as Dark Blue, Polished and Red. A Safari high output alternator in a cast case keeps the bay looking original. Running a work van instead?
