Replacement Bearings, Races, and Seals for Kodiak Disc Brake Kit K2HR79E

Question

Question:

I want to replace the wheel bearings on all 4 wheels of my tandem axle HitchHiker 36foot 5th wheel that we converted to Kodiak Disc brakes. I would like to get one of your kits that has the inner/outer bearing/races along with the cotter pin and flange washer since one axle uses a pin and the other axle which was replaced a year ago by Lippert and has different keepers, The part number from Kodiak is inner bearing=25580, outer= 02475, inner race=25520, outer race=02420. It would be nice to have the seals and both keepers along with it if you have a kit that would include those items. I want the best quality possible, Timken or whoever you recommend. Thanks,

We have everything you would need, but just not in a kit at this time. For bearings you would need # 02475 and # 25580. Race # 02420 and # 25520.

Then for a grease seal part # GS-2250DL.

Based on all of these part numbers it looks like you have Kodiak kit part # K2HR79E on your trailer.
