The Kwikee 375632 is a complete 27-Series automatic step assembly that extends the moment you open your RV door and retracts the moment you close it -- no manual effort, no forgetting to retract before you drive away. Built from heavy-gauge powder-coated steel with solid steel drive rods and stainless steel bushings, this step is engineered for long-term durability in demanding outdoor conditions.
The 27-Series is one of Kwikee's most widely installed single-step electric entry systems, found as OEM equipment on a broad range of Class A, Class C, and fifth-wheel RVs. Part number 375632 ships as a complete step assembly -- including the logic control unit, motor, and switch kit -- so you have everything needed for a direct replacement installation.
The integrated logic control unit manages the open-and-close cycle automatically via door switch signal, and the built-in obstacle-detection circuit stops and reverses the step if it contacts resistance mid-travel. A hidden amber courtesy light illuminates the step tread in low-light conditions, adding a meaningful safety margin when boarding at night.
Step deploys on door open, retracts on door close -- fully automatic via the included logic control unit and door switch wiring.
Motor automatically stops if the step encounters resistance mid-travel, protecting the mechanism and preventing damage to objects or ground obstacles.
Hidden amber LED (or incandescent, depending on build revision) illuminates the tread area to guide users safely onto the step in darkness.
Sealed connectors and weatherproof harness protect against moisture intrusion, corrosion, and shorts -- critical for year-round outdoor use.
The step frame and tread are fabricated from heavy-gauge steel with a black powder-coat finish that resists chipping, rust, and UV degradation better than painted finishes. Drive rods are solid steel for rigidity under load, and the pivot points use stainless steel bushings to resist corrosion and reduce wear over thousands of cycles. This is the same robust construction used in Kwikee OEM applications across major RV manufacturers.
The logic control unit (LCU) is the brain of the 27-Series system. It receives a signal from your RV's door switch when the door opens, commands the motor to extend the step, then reverses the motor when the door closes. The LCU also manages the obstacle-stop feature: if motor current spikes (indicating the step has hit something), it cuts and reverses drive before mechanical damage occurs.
The LCU connects to the RV's 12V DC power supply, a ground, and the door switch wire. Most RVs originally equipped with Kwikee steps will have compatible wiring already in place, making this a straightforward swap for experienced DIY installers.
Part number 375632 is a common replacement for worn, bent, or motor-failed 27-Series steps on a wide range of RVs that left the factory with Kwikee single-step systems installed. Manufacturers that have used Kwikee 27-Series steps as OEM equipment include Forest River, Coachmen, Fleetwood, Thor, and others. Cross-reference your existing step's series label or part number to confirm a direct fit.
