We sell a few of the Kwikee steps with just the frame and not with the motor that you already have, but not in the single step variation so the only option we'd have is to replace the entire unit with another Kwikee 28 like what you sent in a picture of like part # LC3747453. view full answer...
The Lippert Components Kwikee 42 Series Double Tread Electric Step # LC372779 is the entire assembly including motor, wiring, and controller. I confirmed this with my contact at Lippert to make sure you wouldn't be missing anything.
If you have all the components and just need the motor table, then you will want # LC372749.
If you need anything else let me know. view full answer...
