Hello all

Has anyone upgraded their 3500 rear axle and suspension with that of a 4500 or 5500?

I understand I will have issues if I only try to use the leaf springs out of say, a 5500 because the U-bolts are of a different size. I would also upgrade the rear axle because of the loads I haul.

I thought the 3500 could out tow the 5500. Are you just trying to increase your pin weight?

Yes, actually, with the current axle, I am legally only allowed 9600# weight over that axle and if I were to go by the current tires on the 17" rims, I am allowed 11,340#. I can sometime hit 14,000# fully loaded.
