Note: This step assembly includes the steps, motor, and switch kit only. The steps will operate manually through the switch kit.

If you want the complete step assembly that allows the steps to automatically extend and retract with the RV door, you will need a control unit. The switch kit included with this assembly will still work, but if you want to be able to override the automatic retraction, so the steps stay out whether the door is open or closed, you will need a different switch kit. The complete assembly with steps, motor, control unit, and switch kit is available under part number LC3747453.

The included 4-way plug fits into the existing wiring harness on your RV. Most vehicles should have this wiring already set up. In the event that your RV is missing the wiring, a 4-way pigtail is included to help you hardwire the unit to your RV.

Safety Features

The Kwikee steps include several safety features in an effort to prevent injury to you or your passengers and damage to the RV steps. If an obstruction is detected while extending, the steps will halt and retract back into the stowed position. The steps will also retract when you turn on the vehicles ignition, even if the automatic retraction override has been activated, in case you forget to stow them before driving away.

Will Kwikee Electric Steps Work for You?

Electric steps are typically installed on RVs and some travel trailers. The electric steps from Kwikee install and fold up underneath the camper for simple storage. To ensure you choose the correct size for your application, there are a few measurements you will need to take.

Kwikee In and Out

The Kwikee electric steps attach to the underside of the camper chassis, directly beneath the doorway. To decide which size you'll need, locate the space available underneath your camper that lines up with the doorframe, and measure the width and depth. You will need a mounting space that is at least 24-3/4" wide and 8-5/8" deep.

If it turns out you have more or less space beneath your doorway, there are other step assemblies available with bracket sizes ranging from 24-3/4" wide to 37-1/4" wide. A full list of the available steps is below.

Outriggers for RV Steps

Outriggers - metal brackets that act as an extension (LC301704 - sold separately) - may be needed for installation depending on the model of your original stairs. These provide extra length if the old steps are longer or wider than the new.

Once you know where the mounting bracket will go and what size mounting bracket you need, that spot will be used as the "mounting point" to determine how many steps you will need.

How Many Steps Do You Need?

Kwikee Entry Height

To decide on how many steps you'll need, measure from the mounting point to the ground. This is called the entry height. The entry height should roughly match the height of the steps when they're fully extended, plus 6" to 8" to account for the drop from the bottom step to the ground. This measurement will also tell you how many steps you need.

The chart below displays mounting bracket widths in the first column and entry height measurements in the second column. The third column shows the corresponding part numbers. Use the mounting bracket width and entry height measurements you took to determine which part number will fit your RV. Choose the bracket size that is closest to your measurements without going over.

Average Customer Rating:  4.7 out of 5 stars   (154 Customer Reviews)

Replaces the electric step, motor, and switch kit for your Kwikee 28 series RV steps. Motor extends and retracts the step when it receives the signal from the switch kit. Wiring pigtail hardwires to your RV's power.


Upon opening the box, I bench tested the 28 series steps and they worked perfectly. Once the older steps were removed, the installation went easily. I used a floor jack to lift and hold the 28 series steps in place thus allowing me to Mount them alone.


The steps itself work great as far as the delivery when I received them the box was torn and part of the frame was bent.Iwad able to straighten it what I would recommend is better packaging or a different carrier.


The part sent was incorrect, so here we go in other week with an ambulance down. I’ll recap they sent the incorrect step we used it anyway because we wanted something to assist people to enter the ambulance, the switch with the unit they sent was defective it took a half hour on the phone from the service person to understand that, they sent the wrong switch so I spent a half an hour on hold then spoke with the person for 20 minutes, they were supposed to get back to me letting me know they figured out the correct switch and they have not. We’ll see what tomorrow brings?

I think I was misled by the vedio I was expecting a automatic switch and amber step lite like in vedio

To add the automatic open and close feature when the doors open on the RV you would need part # LC379146. For the light kit to be added you would need # LC379414.


The steps were easy to install. They fit perfect. Holes for bolts ligned up perfect. They still work after a year. Would recommend to anyone. ThankYou, etrailer


Because of a unique application, my installation was significantly more involved than standard.E- trailers assistance in resolving the issues was very helpful and professional. Thank you. Darrel

I am so glad I came across, They have what I need in stock, and show you how to use and or install the product.
They have great prices and fast shipping, What else could you ask for!


Great step .... motor seems to run now but step will not come out..
Need some advise on this problem


It works exactly like the original


Sherry S.


Product still works perfect. It’s also a lot quieter than the one we replaced.








The Keikee Electric RV step from was a perfect fit for our Thor ACE motorhome. I would recommend for rv parts and automotive parts replacents.


Everything is great! Except.. the paint was flaking off on the edges. It seems if it was powder coated this wouldn’t have. At least I haven’t seen it before. Other than that.


Direct replacement. Perfect fit!


exactly what i needed to replaced a road damaged unit... this has a slightly smaller profile (6" vs 7")... easy to install... unit showed up in 4 days!



It came very quickly.The box was damaged,but all appears ok. Going to install this weekend,if the weather permits.The one I'm changing out is a exact replacement. Thanks!


The bolt holes should be taped or threaded to 8 // 32
You should sell a bolt kit with all the bolts. And all the bolts to hold up the light and controller
Worked great and was easy to install.


Item was the exact replacement for my 2020 Thor Hurricane. So greatful.


Well built. Would recommend keeping them lubricated at the pivot points with an aerosol grease. Obviously exposed to the road elements and it gets squeaky quick.

    There's a few ways to do it. If you can get the number off of the motor on the step that can help identify what it is. If you can determine what series step it is that helps too. Pictures of the motor and step will help a lot. There are several styles of steps and some have different generations so the key is determining what step you have, what version of it you have and then selecting the replacement motor based on that. So the step you referenced is the Lippert Kwikee 28 Series part...

    In comparing Kwikee Lippert # LC3474453 VS # LC3747451 electric steps (28 Series), I find that the 451 is a basic electric step that goes in or out based on an in-cab switch only. The 453 model additionally includes a control unit, and magnetic door switches that automate extending and retracting the steps. As you mentioned, the 453 has a step light as well.

    The issue you are having with your Kwikee 28 Series Step is a bad motor. I do have an option for you but the cutoff date for replacement parts on Kwikee Steps is 1999. Therefore, they do not make a replacement motor that will work with your Kwikee Step due to its age. The only option you have is a full replacement, the Kwikee 28 Series Electric Step part # LC3747451.

If this is what you have then any other 26 series step would have the same mounting dimensions (20-1/2" wide x 7-1/2" deep) and overall width (25-1/4") so you'd be able to use the Kwikee Electric RV Step Complete Assembly # LC3711363 as a replacement.
