Yes, a Lippert 4,400LB torsion axle will use the same Bearing Kit # BK2-100 as their standard 4,400lb axle. This kit includes the following components if you only need to replace some of the components and not everything.

Outer bearing # L44649
Inner bearing # L68149
Inner cup # L68111
Outer cup # L44610
Grease seal # 58846
Cotter Pin # 165649
Tang Washer # 5-101

We do have the 7-Piece Installation Set # PTW83020 and Seal Puller # PTW1219 which will aid in the installation and removal of the components.
