Hello Mark,
We definitely have a hub that’s going to work for you, but I don’t have a database that tells me what parts are installed on which campers (though it would be pretty sweet if I did).
From my research, it looks like you should have 7,000 lb axles. Since the stickers are torn, I’d recommend double-checking to see if you can make out the axle capacity to confirm.
If it is 7K, you’ll need the Dexter Nev-R-Adjust Electric Trailer Brakes – 12" – Left/Right Hand Assemblies – 7K, part # 23-464-465. You could also go with our etrailer Self-Adjusting Electric Trailer Brakes – 12" – Left/Right Hand – 5.2K to 7K, part # AKEBRK-7-SA. Both are self-adjusting, which gives you one less thing to worry about.
If you go to change the brakes and discover you need hubs as well, the Easy Grease Trailer Hub and Drum Assembly for 7K Axles - 12" - 8 on 6-1/2 - Pre-Greased # AKHD-865-7-1-EZ-K should be correct ones. I would double check your bearing numbers: 25580 (1.75" inner diameter), and outer 14125A (1.25" inner diameter). Or if you do not want to pull those greasy things out, you could measure your spindle. I attached an image that shows where to measure the spindle for bearing sizes.
For the spindle nut, you’ll need a 1" nut, part # 165686.
Getting everything geared up for an upcoming trip? If so, where’s your next adventure?

Hey Mark, did you have a chance to check the axle capacity on your Keystone Cougar to confirm if you need the 7K brakes? I'm curious to know how it worked out for you, as it could help others in a similar situation.
