How do I improve the towing capacity of my Nissan Navara?

I have a Nissan Navara and I want to be able to tow heavier loads. What modifications or adjustments can I make to increase the towing capacity of my truck?

First, you need to consider the weight of your current load and what you want to tow. Look into upgrading your suspension, adding a stronger rear axle, and reinforcing the frame.
