2001-2007 Duramax Transfer Case NP263HD & NP263XHD Range Hub (ZTNP43681)

The range hub slides on the main shaft inside your transfer case to switch between high and low gears. When you shift from 2WD/4WD High to 4WD Low, it moves to give you more torque at low speeds. It teams up with the range fork to pick the right gear.
