Towing Capacity for 4500 & 5500

[Desert Racer]

What is the Max towing capacity (bumper pull & 5th wheel) for the 4500 and 5500?

Actual lbs to pull will depend upon the base wt with people less 26000 lbs, max GCWR of those trucks because of the allison 1000 in the 4500 and the 2100 in the 5500's.

Bumper pull you can go to 15K or so with a few recievers out there, or a pintle hitch frame mounted. 5W will be about the same, as one of those trucks will wiegh in at about 8-12K lbs depending upon the cab, 4wd vs 2wd yadda yadda.

Depending upon how much you need to pull, a GM 6500/7500 or other manufactures class 6/7 rigs would be better for much more than 15k or so, due to better tranny, axle gear, and engine combos.
