tonka, do you mean 15" rims? that won't actually do much for compensation...
Coraddi, your ranger is completely different than ours, you've got the global ranger, which looks like this... (98-2002)
and this is ours, (98-2002 [same generation is being used currently, but the front end looks different])
i haven't done any major digging as to specs and such, it's fairly difficult to filter out all of the north american data, to get brazil spesific stuff from here, but i believe your load capacity is significantly higher, and your axles are stronger, looking at the pictures above alone, you will notice the global has 6 lug rims, where as the north american ranger has 5... even our 1/2 ton full size trucks don't typically have 6 lug...
