I have ordered 390RK-R and one of the things that I put on as an option was the 8000 pound axles my question is what all comes in that upgrade? I can't find anything about it on The Grand Design website. so I only have a day or two before I have to cancel it or I'm stuck with it I'd like to know the details of everything I'm getting for my $5,000... if anyone could give me a link or send me a PDF or something to explaining what all is involved in that I would greatly appreciate it

Typically when the axles are changed out the hub has to be changed also. I would call GD customer support at 574-825-9679 and ask the question.2017 Momentum 376, 2019 Ford F450

Good Morning Dhughes. Welcome to the technical forum.
I have moved your thread to "Ask Grand Design" so you can get input directly from the factory representative.

dhughes838 did you ever find out how much weight gets added when upgrading to the 8k axles with disc brakes? Thanks for posting the original question, I was looking for a similar answer! GDRV-Megan I'm considering the upgrade to the 7K Axle w/Disc Brakes but wanted to confirm that this option also comes with the electric over hydraulic Dexter system?

To the rest of the thread, it seems you could order the 8000 axle upgrade, have Morryde install an independent suspension and use the EOH system that GD provided. This would provide an "official" GVWR sticker of 18,000 lbs. I wonder how much the cost of the IS would be if the EOH system came from GD?2017 Ram 3500 Mega Cab diesel dually, OEM 5th wheel option
