GMC Savana High Output Alternators

Camper conversions on the Savana chassis live on stored power: a lithium house bank, a compressor fridge, a roof fan, lights and often an inverter for cooking. When you are moving between campsites, the alternator is the fastest way to refill that bank. Below, find each Mechman alternator offered for 1996-2016 GMC Savana gas vans. Check your plug, then choose a Savana high output alternator sized to the build.

Charging a House Battery on the Move

Solar helps, but cloudy weeks and short winter days happen. Most van builders rely on driving to recharge, through a DC-DC charger or isolator between the starting battery and the house bank. The bigger the bank and the charger, the more the alternator has to supply while still running the van. A Savana high output alternator lets you run a larger charger without leaving the charging system working at its limit on long highway days or at idle in camp.

2-Pin or 4-Pin: Matching Your Savana

Enter your year and engine in the finder above to see 1996-2016 gas Savana fitment, which divides into two groups by plug style. A 2-pin plug points to one series, and a 4-pin plug to another. Check the connector on your existing alternator before choosing. Our harness and regulator collection covers wiring changes.

Sizing for the conversion

  • 170 Amp: a weekend camper with a small fridge and lights.
  • 240 or 250 Amp: a mid-size lithium bank with a modest DC-DC charger.
  • 320 or 370 Amp: a larger bank, a bigger charger and an inverter.
  • 400 Amp: full-time builds with induction cooking or air conditioning on battery power.

Match the Savana high output alternator to the charger you plan to run, and leave room for the van's own lights, fans and wipers.

Housing Choice and Battery Pairing

For the housing, billet versions are milled from a solid aluminum block and offered in gold, purple, natural and dark blue, among other finishes. Standard housings look like stock. For the house bank, our lithium batteries suit deep daily cycling, and heavy cable from our wiring kits reduces voltage drop on long runs to the rear. Work van owners will find the twin Chevrolet Express page useful, and trail fans can see the Hummer H2 collection. The complete GM and GMC alternator lineup covers more. All are Mechman high output alternators.
