Every factory hitch from DC I've seen is technically a Class 3 Hitch they are rated at 500/5000 weight carrying and 1,000/10,000 weight distribution... DC stamps them as Class 5
I sold mine for $75
The Titan on my truck is:
1,200/12,000 weight carrying and 1,400/14,000 weight distribution it uses the factory mounting holes so the change out took all of 20min with air tools.
