When Advance Adapters released its newest creation, the four-speed Atlas 4SP transfer case, we just had to get a look behind the scenes at what went into it. Our curiosity took us to Advance Adapters' home base in Paso Robles, California. The facility was awesome, full of eye candy that any hard-core wheeler could appreciate, with everything from custom company-owned project rigs to a machine shop containing $100,000 CNC machines, gear cutting equipment, and enough raw aluminum material to make a soda can for Paul Bunyan. Needless to say, we were impressed by our tour. Coincidentally, while we were there, a few of the 40 Advance Adapters staff were assembling the new Atlas transfer cases. So we asked if we could tag along and document the process. Check out what we learned. Advance Adapters receives approximately 100 castings with each shipment. The process begins with castings. These come from Advance Adapters' Southern California foundry in approximately 100-piece lots. These castings are first inspected and then prepped for finish machining.Advance Adapters receives approximately 100 castings with each shipment.

A batch like this Prior to assembly, each case receives a 140-degree solvent bath to remove any loose shavings and/or foreign materials. The heat also aids with the assembly process because the aluminum actually expands slightly. Our assembly technician Jordan Lester also told us the heat makes the cases nice to work with during the colder winter months.Prior to assembly, each case receives a 140-degree solvent bath to remove any loose shavin Each assembly technician has a personalized work station with plenty of space to lay out, organize, and put together each of the three subassemblies that are required for each case.
