What Are The Legal Axle Weights On An Isuzu NPS 75-155 Dual Cab?

What are the legal axle weights for an Isuzu NPS 75-155?


I’m thinking of buying an Isuzu NPS 75-155 dual cab like yours. I can’t find any information on the maximum allowable weights over the front and back axles. Do you know what the legal weights are? And do you know what your truck’s axle weights are when it’s loaded?


You can find the maximum allowable weights by checking the manufacturer’s specification sheets. For example, the Isuzu NPS 75-155 Specifications list them under the “Axles” heading.

The front axle capacity is 3,100kg and the rear is 6,600kg. GVM is of course 7,500kg.

It doesn’t matter whether you buy a single cab or a dual cab. Axle capacities are the same for both.

Our weights when fully loaded including fuel, water and passengers are:

  • Front axle = 2,780kg
  • Rear axle 3,800kg
  • Total = 6,580kg

Dual cabs are generally pretty heavy over the front axle, for obvious reasons. We’ve pretty happy with how the weight is distributed in our truck. Its slight “nose up” appearance in the photo above isn’t due to the load being too far back.

Rather, we had new heavier parabolic springs fitted at the front. So these tend to lift the front up more than usual.

Hope this helps!
