Dual Transfer Case Kit – Nissan Patrol GQ/GU

Nissan Patrol GQ/GU Dual Transfer Case Kit

A dual transfer case enhances the vehicle’s off-road capabilities, improves towing and handling in difficult conditions, and enhances versatility by offering high- and low-speed driving options. These benefits make it a valuable feature for serious off-roaders, heavy-duty vehicles, and those who frequently drive in challenging terrains.

A dual transfer case (often called a three-speed or four-speed transfer case) is a key component in many four-wheel-drive (4WD) vehicles, particularly those designed for off-roading or heavy-duty applications. It provides several significant benefits, especially when compared to a single-speed transfer case. Here are the primary benefits of a dual transfer case:

Marks 4WD designed and manufactured this kit over 15 years ago. Since then, we have made some minor improvements to the kit and significantly changed the main shaft material, which is now 30% stronger.

1. Improved Off-Road Capability

• Low Range Gear: A dual transfer case typically offers a “low-range” gear, which is ideal for low-speed, high-torque applications like crawling over rocks, steep inclines, deep mud, or sand. This low-range gear provides increased torque, allowing the vehicle to move more slowly and steadily, making it easier to navigate tough terrains without straining the engine or drivetrain.
• High Range Gear: The high-range gear is used for normal highway driving or other conditions that don’t require significant torque multiplication, offering better fuel efficiency and higher speeds.

2. Better Control in Challenging Terrain

• A dual transfer case enables better control over a vehicle’s speed and power, particularly in challenging off-road situations. This is particularly critical when driving in environments where precise throttle and traction control are essential, such as on slippery surfaces or uneven ground.
• The ability to switch between low and high ranges allows drivers to adjust their driving strategy to the terrain, thereby reducing the risk of getting stuck or damaging the vehicle.

3. Enhanced Traction and Stability

• The low-range gearing enables smoother, more controlled braking and acceleration in rugged conditions, thereby reducing the likelihood of wheel spin and loss of stability.

4. Improved Durability and Longevity

• A dual transfer case system is often built to withstand the demands of extreme driving conditions, making it more durable in off-road and heavy-duty applications. Providing extra low-range gears helps avoid over-stressing the engine and drivetrain when driving at low speeds or in tough terrain.
• The ability to shift into high gear for regular driving can help reduce wear and tear on the vehicle’s mechanical components when not off-roading.

5. Greater Control over Speed and Power

• The additional gear options offered by a dual transfer case system allow drivers to adjust the balance between speed and power. When more torque is needed, the low-range setting can provide more power at slower speeds, which is often crucial in off-roading.
