Kwikee 3747452 Short Term

Kwikee electric RV entry steps provide an effortless, convenient way to enter and exit your RV. The steps are wired to your RV's door and feature an automatic extension, unfolding when the door opens and retracting when it closes. This differentiates the steps from the alternate manual pull-out steps.

Motor, Gearbox, Linkage, and Control Unit

The updated Kwikee steps manufactured since 1999 require the integrated motor, gearbox, and linkage (IMGL) setup to power the steps. The motor provides the power, the gearbox turns the linkage arm, and the linkage pushes the steps out and pulls them back in when rotated by the gearbox.

The motor powers the control unit, which senses when the RV door opens and closes, extending and retracting the steps in tandem.

The included 4-way plug fits into the existing wiring harness on your RV. Most vehicles should having 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 24-1/4" wide and 8-9/16" 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 24-1/2" wide to 36-3/4" 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.

Arrived in good condition, and at expected delivery date. Very happy with the advise and service from you guys 621725

Still working well though Kwikee decided to go with a different polarity for the new step
Bill - 04/12/2020

Good price... delivered promptly...what more can one ask for. Kwikee steps well not so happy with them...I’m on my 3rd one in 3 years... although one was impacted by a large piece of asphalt on the road. Seal the wires going into controller will prevent moisture entering it... one failed due to that. 892119

Plug and go, no problems 880276

- LC3747452

Everything that had to do with my purchase (customer support, delivery, product quality) was perfect. The only reason it did not get five stars is because there is no disclaimer that the motor in the steps have had their polarity reversed. in other words the steps will close when the door is opened, and open when the door is closed. There is a magnetic switch that also needs to be replaced, the new stitches are considered a Normally Open switch, some model motorhomes have Normally Closed switches installed at the factory just inside your screen door. They are simply a magnet that tells the control module wether the door is open or closed. Check before you order, etrailer carry them and are easy to install, just stinks having to pay shipping twice. 819300

Received my Kwikee Motorhome step today. It was replacing my 17 year old step that I had been having intermittent problems with recently. It was a perfect replacement, plug and play, and I expect it will last me another 17 years. Thanks etrailer!! John V 767810

Product works great, but the best part of my experience was the how to video on your site. Watched the installation video with the best tips on installation and the change out was accomplished in less than an hour. Thanks for adding that value to the product. Well done. 749178

This step works great. I was very surprised that it worked for my rv. Thank you. 673420

- LC3747452

The steps arrived as expected. They are identical with the exception of the wire for the outdoor light. I have taken the old ones off but not put the new ones on. The person I spoke with was very helpful with the steps. Installation begins in the morning. I am only giving 4 stars due to the lack of instructions. I am having to find the links online. It could have made suggestions for making the project easier or something even though it appears to be quite simple. 672236

Great, it is easy to hook up and we feel safe towing our jeep.

We replaced a damaged step a year ago. The new one from etrailer has performed great! We really like working with etrailer. 658765

Purchased a replacement step for our 2 year old coach that was inoperative when we bought it slightly used. The original step was poorly maintained by the original owner and very erratic. The replacement was exactly as described, came with good instructions and has performed well this past year. Pricing from trailer was good and customer service excellent. Will shop them again when needed. 658289

  • Recommended Step for 2007 Ford Ranger Truck
    The Lippert Kwikee 28 Series Electric Step # LC3747452 is not designed for use on vehicles like a truck.

If you were to install this on your vehicle you absolutely would need to run a power wire # 10-1-1 from the battery to the switch and run the negative to ground on the vehicle frame. I've...

  • Motor Not Shutting Off on Lippert Kwikee Series 28 Electric RV Step
    I spoke with my contact at Lippert regarding your Kwikee 28 Series Single Electric Step # LC3747452. He stated that the most likely cause for the motor not to shut off on your unit is a faulty gear. The damaged part is simply not able to offer any resistance to shut the motor off. For a Replacement Repair Kit, you will want to use part # LC379769. This is designed for the Series 28 Electric Step and includes the integrated motor, gearbox, linkage and control unit.

  • Recommended Replacement Single Step for a 2001 R-Vision Motorhome
    The Lippert Kwikee 28 Series Electric Step # LC3747452 that you referenced is a great single step option that is extremely popular as an OEM application and does a great job. This step has mounting bracket dimensions of 24-1/4" wide x 5-7/8" tall x 8-9/16" deep so if your current mounting dimensions match up to this then you are good to go!

  • RV Step Recommendation for 2010 Fleetwood Pulse
    I wasn't able to find the original steps that your 2010 Fleetwood Pulse came with but it appears to be a Lippert Kwikee 28 Series like the part # LC3747452 that you referenced. You can verify this by measuring the width of your steps and if they are 23-3/4 inches this step will fit and work well.

  • Could Kwikee 28 Series Step Attach to Golf Cart
    It's probably possible but you'd want to find a local fabricator most likely and see what they think they could come up with. The part # LC3747452 could be welded to the bottom of the golf cart assuming there's access to the frame of it easily.
