The Lippert 379160 "A" Linkage Gearbox is the direct replacement gearbox for Kwikee electric entry steps on a wide range of RV models. When your steps stop extending or retracting reliably, the gearbox is one of the first components to inspect -- this heavy-duty, zinc-plated steel unit restores full operation and is built to handle years of road vibration and weather exposure.
Kwikee electric steps are found on a large percentage of Class A, Class C, fifth wheels, and travel trailers. Over time, the linkage gearbox -- the mechanical heart that translates motor rotation into step extension and retraction -- can wear, strip, or suffer corrosion damage. This Lippert-branded replacement (part 379160) is specifically engineered for the Kwikee "A" linkage system and drops in without modification on all compatible step series.
The gearbox is fully enclosed, protecting the internal gear set from road grime, moisture, and salt spray. The zinc-plated steel housing resists corrosion in the harsh under-coach environment. Each unit ships with two installation washers so you have everything needed to complete the swap.
Fully sealed gearbox keeps dirt, water, and road debris away from internal gear components, extending service life in under-coach mounting locations.
Heavy-duty steel construction with corrosion-resistant zinc plating handles the vibration, moisture, and road salt exposure typical of RV entry step installations.
Fits Kwikee electric step series 22, 23, 28A, 30, 32, 33, 34, 35, 36, 38, and 40 -- covering a large share of OEM and aftermarket Kwikee installations.
Manufactured domestically to Lippert quality standards. Includes two washers for installation -- no additional hardware required for most applications.
This gearbox is designed exclusively for the Kwikee "A" linkage arm configuration. Before ordering, confirm your existing step series number -- it is typically stamped or labeled on the step motor housing or mounting bracket. Compatible step series are listed below.
This unit is a direct replacement for Kwikee cross-reference part number 1101425. It is also sold under the AM Equipment part number 110-1030. All three part numbers (Lippert 379160, Kwikee 1101425, AM Equipment 110-1030) refer to the same gearbox assembly.
The gearbox mounts to the step motor and linkage arm. When replacing, ensure the old gearbox is fully removed from the motor shaft before installing the new unit. The two included washers seat between the gearbox mounting face and the step frame in most applications. Verify linkage arm orientation matches your existing setup before final tightening.
After installation, apply a light coating of white lithium grease to the linkage pivot points and gearbox output shaft. This reduces wear and helps prevent the corrosion that typically causes gearbox failure in the first place. Inspect the linkage arms for cracks or bends while the gearbox is out -- bent arms can overload a new gearbox quickly.
This gearbox fits the "A" linkage configuration only. Kwikee also produces "B" and other linkage variants for different step series. If your series number is not listed above, or if your existing gearbox has a different arm geometry, verify the linkage type before purchasing to ensure correct fitment.
