Answered by Sara H. Ext 874 from on

Does the locker have the required bearings included?

Asked by km from on

No, this Eaton E-Locker does not include the carrier bearings. The bearings are included in the installation kit, which you can find here []. We understand that this kit includes more than you are asking for, but we recommend replacing all the included bearings, seals, and shims, as it is cheap insurance to make sure that nothing goes wrong in the future. I hope this information is helpful. Thanks!
