The goal of Ultimate Adventure is building a street-drivable yet trail-tough 4x4, and that's why we chose Dynatrac's DynaLoc selectable hubs for our front axle. These same hubs survived the abuse of a Cummins engine and 42-inch rubber on our UAJK build a few years back, so they should be fine with 400-plus horsepower and 37s. The unique design is such that if there is an unlikely failure, the hubs will go to the locked position, ensuring that you make it off the trail.
