The direct OEM-style replacement gearbox and motor for Kwikee Link Assembly "B" step systems. Purpose-built for triple and quad-step configurations, and compatible with select double-step assemblies including the Kwikee 28-Series, this unit restores full retract and extend force to worn or failed step drives without replacing the entire step assembly.
When your Kwikee electric steps become sluggish, fail to retract fully, or stop moving altogether, the gearbox and motor are usually the first components to wear out. Lippert part 369545 -- also catalogued as AM Equipment 110-1023 and Thor part number 0372438 -- is the correct replacement unit for Link Assembly "B" configurations.
This assembly combines the 5:1 reduction gearbox and high torque 12V motor into a single bolt-in unit, simplifying the repair and eliminating the need to source motor and gearbox separately. The 18 Nm torque rating delivers the mechanical advantage required to move multi-step assemblies reliably even when travel and road grime have increased friction in the linkage.
Multiplies motor torque five-to-one, giving the drive mechanism the force needed to extend and retract heavy multi-step assemblies consistently.
High torque output handles triple and quad-step loads. Adequate for the added weight and linkage friction common in larger coach entry systems.
Motor and gearbox ship as one pre-assembled unit. No separate sourcing or alignment required -- mount it and connect the wiring harness.
Sold under Lippert 369545, AM Equipment 110-1023, and Thor 0372438. Broad OEM and aftermarket compatibility across coach brands.
Kwikee electric steps use two distinct link arm geometries -- Assembly "A" and Assembly "B" -- which determine the mounting orientation and drive attachment point of the gearbox. Assembly "B" is the correct configuration for most triple-step and quad-step Kwikee units, and is also specified for certain double-step models, most notably the Kwikee 28-Series. If you are unsure which assembly your step uses, check the step's label or measure the existing gearbox mount orientation before ordering.
This gearbox assembly is commonly used in the following Kwikee electric step configurations:
Look at the gearbox mounting bracket and the direction the output shaft faces relative to the step frame. Assembly B units have a specific orientation that differs from Assembly A. The step's original part number sticker -- typically found on the motor housing or the step frame rail -- will confirm which assembly is installed from the factory. When in doubt, contact Lippert technical support with your step's serial number.
Replacing the gearbox and motor on a Kwikee step is a straightforward process for anyone comfortable with basic 12V wiring and light mechanical work:
While the gearbox is removed, inspect the link arms, pivot pins, and nylon bushings for wear. These small components are inexpensive and often contribute to step sluggishness. Replacing them at the same time maximizes the life of the new gearbox motor assembly.
Installing a Link Assembly "A" gearbox in an Assembly "B" application (or vice versa) will result in improper step travel geometry and potential mechanical damage. Confirm your step's assembly designation before installation.
