The name is legendary and synonymous with rock crawling and off-road vehicle performance. Atlas Transfer Cases have won over the industry for their superior performance, bullet proof design and their ability to get you anywhere you want to go. The Atlas Transfer Case is sure to change the way your vehicle performs off-road. You will benefit greatly by understanding the Atlas characteristics and how to apply them for the ultimate in performance!
Through the analysis of other successful transfer case designs, Advanced Adapters 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 vehicles with centred rear differentials. The solid, one-piece case design is manufactured from 356-T6 heat-treated aluminium 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 customise the transfer case to your vehicle. We offer several upgrades, options, and different configurations for this transfer case.
Choosing a Gear Set:
The 2 speed Atlas transfer case has 6 different low gearing options to suit the needs of your driving habits and your drivetrain components. Along with the these different Atlas 2 speed ratio options, Advance Adapters are now producing a 4 speed Atlas transfer case. The 4 speed Atlas gives you 3 low ranges & 1 high range - a few more choices when it comes to 4-wheeling. You can now have the ultra low gearing for rock crawling, a low range gear for trail use, and mid range for sand and mud. Whether you’re looking at the 2 speed Atlas or the 4 speed Atlas, your ratio options will be diverse.
The wide variety of Atlas gear ratio options have been designed to accommodate any type of drivetrain combination. Please be aware that the lower the final drive ratio gets, the harder it is to stop the vehicle when in gear. Larger brakes will be required to slow the vehicle. Shifting the transmission into neutral on an automatic or depressing the clutch on a manual will be required to bring your vehicle to a complete stop.
