Atlas 3.8 Transfer Case (CALL TO ORDER)
The Advance Adapters Atlas gear-driven transfer cases are the ultimate in gearing and strength. With over 10,000 units sold, the Atlas 2 speed is the solution for combining both on and offroadperformance.
The Atlas is available for both left and right hand vehicle applications with centered rear differentials. The solid, one-piece case design is manufactured from 356-T6 heat-treated aluminum alloy. This material is also used for the structural access cover and all other exterior components.
The massive gears are helical cut and synchro-equipped for quiet performance and "shift-on-the-fly" capability. These gears are supported by needle bearing elements, precision matched to strong 8620 shafts. The ruggedly designed output shafts are amply supported by large taper bearing sets. The Atlas also features a unique twin stick design to deliver crisp, quiet operation.
