Available of 7k Rated DeeMax Disc Rotor Kit for Dexter 7k Axle 2024 Grand Design 3803GK Influence

Updated 10/22/2026 | Published 10/21/2026

Question:

Does this kit fit a Dexter 7K axle part number 11507557 on a 2024 Grand Design 3803GK Influence 5th Wheel? Is a kit available with rotors with thread in grease caps? Maxx Coat calipers?

Hey Mark, yes the DeeMaxx Disc Brakes # DE78YR that you referenced are a confirmed fit for the 7k axles of your 2024 Grand Design 3803GK Influence. Then for a similar version of this that comes with thread in style grease caps we have the part # DE65NR. The calipers are stainless steel and the hub and rotor are maxx coated.

Are you in an area that gets a lot of salt on the roads?

We are in Maryland and it is a concern here. Thanks for the information!

It looks like this kit will not work on my 7K axles as they use 14125A outer brarings and these DeeMax hubs use 02475 outer bearings for an 8K axle?

@MarkT good catch! But the good news is that both of those bearings have the same inner diameter which means it will fit on your spindle the exact same. The outer diameter difference won't make a different.
