part no. 19559-010*
*This Eaton limited slip differential requires special bearings. For axles with small bearing bores (race O.D. of 2.89"), usually found on vehicles prior to 1999, bearing LM-102949 and race LM-102911 are required. For axles with large bearing bores (race O.D. of 3.06"), usually found on vehicles from 1999 to present, bearing LM-603049 and race LM-603012 are required.

 

Thanks for the replies everyone.

 

No special bearings are required when used in a NBS truck, just so you know. Just use the stock bearing number.
Also, try Randy's, National Drivetrain, Nationwide Diff.

Edit- NM I didnt realize that Eaton actually updated their site. People were actually buying the bearings and were very angry after they would get the pressed on without checking them first.
