Hello Dennis,

You can use your current Chinese races, and just get the bearings from the Timken Bearing Kit, 14125A/25580 Bearings, 14276/25520 Races, GS-2125DL Seal # TMK32VR.

You will want:

- Inner bearing: Timken Replacement Trailer Wheel Bearing - 25580 # TMK44FR

- Outer bearing: Timken Replacement Trailer Wheel Bearing - 14125A # TMK54FR

Also, don't forget some grease seals if you do not already have some on hand.

- Timken: Timken Grease and Oil Seal - Double Lip - I.D. 2.125" / O.D. 3.376" - 440972 # TMK38ZR

- Chinese seal: Grease Seal - Double Lip - 2.125" ID - 3.376" OD - GS-2125DL # GS-2125DL

One last thing, if you don't have some grease on hand either, make sure you grab some LubriMatic Prime Guard High Temperature Wheel Bearing Grease - Red - 16-oz Can # L11380.

What kind of trailer are you working on? Getting things geared up and ready for a trip? If so, where are you headed?
