Hey Thomas.
Thank you for providing all that information, helps tremendously.
For brakes you will need the etrailer Electric Trailer Brakes - 8K # AKEBRK-8. Includes left and right, so you will need two sets. I recommend verifying you have the 4-bolt mounting flange spaced 3-5/8" horizontally and 3-7/16" vertically, center to center. If you need/want new mounting hardware then # BRKH122508 will work, one set per axle.
For your bearings and seals, you will need # LC85ZP. This kit contains the bearings, seals, and races for one hub. You will need 4 kits. This kit supports the factory specs for your LCI80 axle.
If you are looking for new hubs and drums as well then you can scrap the # LC85ZP and go with 4 # AKHD-865-8-EZ-K which come with your hub and drum assembly, along with your bearings, races and seals. I've attached a photo of the measurements of these parts below so you can match and verify before moving forward.
Do you have any trips planned with your Momentum once the brake work is finished?
