This got me thinking. If all of the parts on a 3/4 ton truck is identical to a 1 ton besides the rear suspension. What would be the difference between swapping the 3/4 ton suspension for the 1 ton suspension increasing effective capacity -or- adding air bags/Timbrens/Sumosprings to the 3/4 ton suspension that effectively increases it to the same carrying capacity?
I know you will never be able to change ratings because that would cost a lot of money to send it to a final builder, however, you can increase the actual carrying ability by either swapping the suspension to a 1 ton or adding suspensions aides that allow it to carry the same weight.
What would be the difference in what these two options can safely and reliably tow/haul if they both increase the carrying ability the same amount?
