Question:
Looking for the Deemaxx Disc Brake Kit W/ Actuator For Tandem Axle Trailer 2019 Grand Design Solitude 373FB. Your web search when filling out your vehicle is showing the install kit with tri axles. All Solitude are tandem Axle, and I would like to remove the drum brakes and install disks.

Hey David! The DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers item # DE46AR will work so long as you have idler hubs with a 8 on 6-1/2 lug nut pattern like item # DE46VR. These are slip on rotors so you're definitely going to need some idler hubs too. They are sold individually.
It looks like your 2019 Grand Design Solitude 373FB has 7k axles with inner bearing item # 25580 and outer bearing item # 14125A. The DeeMaxx Trailer Idler Hub for 7,000-lb Axles - 8 on 6-1/2 item # DE46VR would definitely fit these but I recommend confirming before ordering.
You can send me a picture of the axle tag to the email address you receive this response from or pull one of the hubs and check the part numbers stamped into the sides of the bearings.

Jarred, wouldn't the de66ar? Other than that comes with half inch wheel bolts instead of 9/16.
