Atlas Input Shafts

Atlas transfer cases are engineered and constructed to withstand more punishment than typical drivetrain components. Over time, though, a transfer case input shaft can suffer damage or wear out, causing issues like slow engagement, fluid leaks and slipping. The seals are even more prone to damage since they are more affected by impacts, extreme temperature changes and other factors. You may also need a replacement shaft input because you've switched to a transmission that requires a different spline count. Whatever the reason you need to replace these components, Advance Adapters is here to assist you.
