Step on and off your RV with confidence. The Kwikee 28 Series single electric step automatically extends the moment you open your door and retracts the moment you close it -- no buttons, no manual pulling, no forgetting to stow before you drive. At 24 inches wide and rated to 750 lbs, it handles everything from a quick grocery run to a muddy campsite exit in full gear.
The Kwikee 3747453 is a direct-fit, single-step replacement assembly designed for RVs originally equipped with Kwikee 28 Series electric step systems. It ships as a complete kit -- step with motor, logic control unit, and door switch kit -- so you have everything needed to get back on the road without sourcing individual components separately.
The 12V DC motor drives solid 3/4-inch steel drive rods through stainless steel bushings, giving this step the mechanical durability to handle thousands of open-and-close cycles without loosening or binding. Air-pressed rivet fasteners at every joint eliminate the slop that develops in welded or bolt-joined competitors over time.
Step deploys when the door opens and retracts when the door closes. Fully automatic -- no manual operation required.
Motor stops immediately if the step encounters resistance during travel, protecting the mechanism and anyone nearby.
Built-in amber light illuminates the step tread in low-light conditions -- useful at night or in dimly lit campsite areas.
Textured non-skid surface and a reflective yellow safety strip improve footing and visibility in wet or dark conditions.
The step frame and tread are built from heavy-gauge steel with a black powder-coat finish that resists rust and road corrosion over years of outdoor exposure. Drive rods are solid 3/4-inch steel -- not hollow tube -- and the pivot points use stainless steel bushings that resist galling and corrosion even when exposed to road spray and moisture.
Wiring and connectors are weatherproof-sealed, preventing shorts and corrosion in the system -- a common failure point on older or budget electric steps.
This assembly is designed as a direct replacement for RVs originally equipped with Kwikee 28 Series single electric step systems. It is also known and catalogued under part number 902809025. If your existing step bracket and wiring harness are sized for the 28 Series, this unit installs without modification to the coach structure.
The 28 Series is a widely used Kwikee step platform found on travel trailers, fifth wheels, and Class A/C motorhomes from multiple manufacturers including Coachmen, Forest River, Keystone, and others. Confirm your existing step width and series number before ordering.
The step mounts to the coach's existing step bracket. Electrical connection is made through the included door switch kit and logic control unit, which tie into the coach's 12V DC system. The door switch triggers automatic deployment; the logic control unit manages motor timing, obstacle detection, and shutoff logic.
