1. Atlas Transfer Case - 2 Speed Units

Through the analysis of other successful transfer case designs, we have manufactured a rugged, all gear-driven transfer case. Combining the latest in CAD/CAM technology and years of in-house CNC machining capabilities, the Atlas transfer case is sure to bring you the utmost in dependability and performance. 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.

The Atlas transfer case offers you the ability to customize the transfer case to your vehicle. We offer several upgrades, options, and different configurations for this transfer case. Atlas is the ultimate gear driven transfer case. CASE: Material: 356-T6 Heat Treated Aluminum Weight: 110 lbs.
