Hello Rich, thanks for reaching out. In this case, yes you can. Both the 600 lb Fastway e2 hitch and the 800 lb version use the same head unit part # FA92-02-1255, so the bars are interchangeable. To upgrade to the 800 lb bars you will need the following:
- Replacement Trunnion Spring Bars for Fastway e2 Weight Distribution Systems - Qty 2 - 800 lbs TW # FA92-01-0899
What kind of camper are you using this with?
