Electric RV steps depend on an internal gear plate to drive smooth extension and retraction each time the entry door opens and closes. When that gear plate wears out, steps can bind, stick, or stop moving altogether. This Lippert kit is an exact-match gear plate for both single and double electric step assemblies.
It's a straightforward repair for Lippert step assemblies across a range of step model series, without needing to replace the whole step unit.
Reference your step's model number before ordering to confirm it falls within the compatible series.
