Atlas II Manual
Atlas 4 speed
This unit is functionally a Klune-V Goliath bolted to either a
3.8 or 2.0 Atlas. (Klune-V /
Atlas Combo - Article) There is an advantage to this Advance
Adapters version: By purpose-engineering the combo, Advance
Adapters has done a nice job of integrating the assembly, shortening
the overall combo by 3.5". Another benefit of this system is
that the Atlas 4-Speed as a unit costs less than buying a Klune and buying
an Atlas 2 speed and combining them
If you want to hear the arguments why you want a 4Speed transfer
case system, they are thoroughly covered on our Klune-V
Extreme Underdrive websection.
The Atlas has been installed in both
full and down size vehicles such as Jeeps, Broncos, Explorers,
Dodge, Chevy & Ford Trucks. These units can be found in daily
driven vehicles, all the way up to the extreme rock crawling
vehicles.
