Hey Mark! From what the Grand Design parts site shows your 2023 Momentum 395MS has 7k Lippert axles. The correct replacement is the Trailer Hub and Drum Assembly for Lippert ABS System # LC49PX.

Do you just need the hub/drum assembly or do you need brakes as well? If you want to replace the brakes they are the Electric Trailer Brake Assembly for Lippert ABS Hubs - 12" - Left/Right Hand # LC83PX. These don't come with new sensors so you will need to use the existing sensors with the brake assemblies.
