Question:
I currently have an 8k e2 wd hitch. I want to go with a 10 or 12k. Can I just buy the new square bars or do I need to buy a whole new kit? Thank you.

Hey Zach, welcome back! You can indeed swap out the spring bars. The head on the Fastway e2 Weight Distribution Systems, like your 8K item # FA92-00-0800, is the same for the 6,000 lbs - 12,000 lbs rated systems.
To upgrade to 10,000 lbs, you'll need the 1,000 lbs Replacement Trunnion Spring Bars item # FA92-01-1099.
To upgrade to 12,000 lbs, you'll need the 1,200 lbs Replacement Trunnion Spring Bars item # FA92-01-1299.
You'll also want to make sure your hitch ball is rated for the higher weight. We have the 2-5/16" Hitch Ball for Equal-i-zer Weight Distribution Systems item # EQ91-00-6120 that has a 12,000 lbs capacity.
Did you get a new trailer or are you just wanting a high capacity weight distribution hitch?

Hey Zach, how did the upgrade to the higher-rated spring bars on your Fastway e2 hitch turn out? Did the 1,000 or 1,200 lb bars give you the extra support you were looking for? Your update could make it easier for others thinking about the same change.
