This aftermarket modification significantly alters the gear ratio within a specific transfer case, the New Process 205 (NP205). It replaces the stock gearing with a set that provides a 4:1 low-range ratio. As an example, for every four rotations of the engine, the output shaft turns once when in low range, drastically increasing torque multiplication.
The installation of this component provides substantial advantages in off-road applications. Its increased torque output at low speeds allows vehicles to navigate challenging terrain with greater control and reduced wheel spin. Historically, enthusiasts seeking enhanced off-road performance have often turned to modifications of this nature to improve their vehicle’s capabilities.
