Every modernized classic car and truck built by Velocity is meant to be driven, so we only source the best parts for our builds. When it comes to the rugged 4x4 versions of the Velocity classic truck restomods, each is equipped with the Atlas two-speed transfer case—one of the most respected and sought-after upgrades for custom, off-road builds.
Here’s a closer look at why it’s the only transfer case used on the Velocity 4x4 trucks; these include the vintage Ford Bronco, Ford F-250, classic Chevy K5 Blazer, and International Scout.
Atlas & Velocity Classic Truck Restomods
At Velocity, the goal is to transform classic American vehicles into modern driving machines without losing their vintage appeal. This process involves upgrading the drivetrain, suspension, and other critical components to handle the rigors of both off-road and on-road driving. That’s the case with Velocity 4x4 builds since they all use modernized engine/transmission setups and most feature upgraded Roadster Shop chassis.

There are two different versions of the Atlas transfer case, but Velocity 4x4s are fitted with the two-speed unit with dual stick controls for front and rear output control. This is ideal for Velocity’s high-end classic truck restomods, which are expected to deliver peak performance and reliability without sacrificing the off-road capability that made these trucks so popular in the first place.

Take, for example, the vintage Ford Bronco and classic Chevy K5 Blazer. Each of these vehicles has a legacy rooted in off-road enthusiasm, and this choice of transfer case ensures our 4x4s can tackle rugged terrain without breaking a sweat. Whether rock crawling, sand dunes, or muddy trails, the Atlas two-speed transfer case gives the driver the control and power needed to handle any challenge.
The durability of the Atlas two-speed transfer case starts with its gear-driven design. This provides for a more compact size that better matches a modern transmission and delivers increased strength and reliability compared to the chain-driven transfer cases found on most modern 4x4s.
How To Use The Atlas Two-Speed Transfer Case
At its core, the Atlas two-speed transfer case is a highly engineered component that allows drivers to switch between high-range and low-range gears, providing the flexibility needed to tackle a variety of terrains with ease. This flexibility makes it a top choice for serious off-roaders and custom 4x4 builders alike. Here’s a helpful video from Advance Adapters showing how to operate the Atlas transfer case:
The part-time 4WD system means that the driver must engage the transfer case when desired, and while the dual sticks might look overwhelming, they are easy to use. As shown in the video above and the image below (taken from the Velocity Ford Bronco owner’s manual), the two sticks each have three positions. In addition to the transfer case operation, Velocity 4x4s also feature Warn manually locking front hubs, which also must be engaged for the four-wheel drive to function.

The transfer case is the defining component in the drivetrain of a 4x4 truck, responsible for distributing power from the engine to both the front and rear axles. It is the connection between the transmission and the differentials, ensuring that all four wheels receive power when needed. This is essential for off-road driving or when navigating challenging terrains like snow, mud, or steep inclines, where maximum traction is required.
In a typical rear-wheel-drive vehicle, only the rear wheels receive power from the engine via a single driveshaft, but 4x4s use a transfer case that splits power between the front and rear axles. Transfer cases also allow for variable speeds depending on the level of traction required: 4-High is for moderately loose or slick terrain, while 4-Low changes the gearing to get out of more challenging situations.
Whether you’re looking at a vintage Ford Bronco, rugged Chevy K5 Blazer, or any other Velocity 4x4 classic truck restomods, the Atlas transfer case provides the control, durability, and versatility needed to tackle any adventure. It’s the ultimate choice for those who want the best in both performance and reliability, making it a perfect match for the high standards of Velocity.
