Hello James,

We definitely have the parts you need, but I do not have a database that supplies me with what is put on what trailer. Life would be a little sweeter if such a list existed.

Based on my research the axle capacity on the 2016 Keystone Alpine can vary on what floor plan you have. The 7K axles are the most common, so that is what I am going with (you will want to check your axle tag to confirm that is what they are rated for).

For brakes you will want (2) sets of our etrailer Electric Trailer Brakes - Self-Adjusting - 12" - Left/Right Hand - 5.2K to 7K # AKEBRK-7-SA.

For 7K hubs the most common hub is the Easy Grease Trailer Hub and Drum Assembly for 5.2K - 7K Axles - 12" - 8 on 6.5 - Pre-Greased # AKHD-865-7-2-EZ-K with inner bearing 25580 (1.75" inner diameter), and outer bearing 14125A (1.25" inner diameter). You will want to pull one of your hubs off and get the bearings out to confirm the numbers, or measure the spindle (please refer to image I attached) to see if the bearing measurements are the same. Also, this hub has a 8 on 6 1/2" bolt pattern. You will need to order (4) of the hubs.

If you check your axle tag, and bearings and they are not what I suggested, please let me know what you do come up with so I can get you the correct part numbers. I am sorry I do not have more definite answers for you.

Getting things geared up for your next adventure? If so, where are you headed?
