Question:
Hello. I am looking at an expert article that was recommended to me. I have a couple questions. I know I am going to need bearings and seals. I was considering trying wet hubs. But do not know the pros and cons. Can you recommend the bearings and seals for this kit and also advise on the wet hubs vs conventional grease

Hey Eric, thanks for reaching out!
The Kodiak Disc Brake Kit # K2HR526D you're looking at is the best setup when combined with the Hydrastar Electric-Hydraulic Actuator w/ Line Kit # CAR-HBA16-2 in that answer page you referenced.
If you were to switch to an oil bath setup you'd need the kit # 8-219-9UC3-A you'll have to switch your wheels to an 8 on 6-1/2" bolt pattern as well, and it isn't really worth it. Oil bath setups typically run cooler than a grease setup, but they are much more likely to fail as well so grease is the most reliable and is why I recommend sticking with that route.
