Features to know about

Stable, Sure-Footed Entry: 23-5/8" Wide Electric Step with Non-Slip Surface

This Kwikee 28 Series electric step gives you a stable 23-5/8" wide x 10-1/2" deep platform with a 7-1/2" drop/rise, so stepping up feels natural and secure. The tread surface has built-in non-slip texture and reflective strips to help you see it clearly in low light. With a 300 lb weight capacity, it stays firm with no flex when you step on it.

Reliable Operation Every Time: 12V Motor and Manual Switch Control

The included 12V motor extends and retracts the step smoothly when you flip the in-cab switch. The motor and gearbox are built to handle daily use without strain. It’s a straightforward setup—no control module needed—so you can run the step manually exactly when you want it out or stowed.

Built to Last in All Weather: Powder-Coated Steel and Weatherproof Wiring

The step frame is made from sturdy, powder-coated steel that stands up to dirt, moisture, and road spray. Solid steel drive rods and stainless steel bushings keep the mechanism tight and smooth over time. Weatherproof wiring and sealed rivets at pivot points hold up well through seasons of travel and rough conditions.

Smart Safety Design: Automatic Retraction on Obstacle Contact

A built-in safety feature stops and retracts the step if it hits an obstacle while extending. It also pulls the step in automatically when the ignition turns on, preventing it from being left out while driving. These safeguards help avoid damage and add peace of mind whenever you’re on the move.

Fits Existing Mounts: 24-1/4" x 8-5/8" Mounting Plate and Standard Wiring Plug

The mounting plate measures 24-1/4" wide x 8-5/8" deep with a 22" x 6-1/2" bolt pattern, which lines up with standard Kwikee setups. A 4-way plug connects to your existing harness, and a pigtail is included if you need to hardwire. Extended height is 9-5/8", folded height is 6", making it compact yet sturdy for everyday use.

by:

company cannot even afford 4 bolts for mounting. no installation instructions, no warranty card. minimum basic customer service is no existent



by:

Customer service is great! They keep you informed the entire order of your order!
I was expecting the steps, the motor and the controller. After looking at the pictures, I spotted the arm assembly in the gearbox.
I called to verify if that was part of the price. It was! I didn’t have to use the gearbox and the arm assembly from my old steps!
Plug and play! Thanks etraialer

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



by:

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?

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.



by:

I am so glad I came across etrailer.com, 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!



by:

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



by:

Etrailer.com is top shelf. Great products and outstanding service. Their webpage is user friendly. Do Not hesitate to do business with these people. I have conducted several orders with them with 105% satisfaction.



by:

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



by:

Timely delivery.



by:

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.



by:

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.

  • Replacement Motor for Kwikee 28 Series Step Made In 1988
    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 you want to switch to a more cost effective manual pull-out step you can use the Lippert Manual Pull-Out Step part #...

  • Is The Frame Of The Kwikee 38-Series RV Electric Step Available Separately
    Hi Nick, It looks like Lippert doesn't offer just the frame of the 38-Series Kwikee steps by themselves so you would need to either purchase the complete assembly # LC3723383 or the frame, motor, and switch # LC372338 in order to get a replacement frame. Personally, I'd just go with the whole assembly at that point to ensure every part is new and functions correctly rather than find out you need to replace something else after you're already in the middle of the installation. If you...

  • Recommended Step Assembly Replacement For A 2008 Freightliner With Toter Camper Body
    If you're wanting to replace the complete assembly of your 2008 Freightliner's steps then I'll just need to know the entry height (ground to mounting plate) and the width of your mounting plate. For example the Replacement Step, Motor, and Switch for Kwikee RV Electric Steps - 28 Series - 23-5/8" Wide # LC3747451 you linked to would be a fit for an entry height of 15-5/8" - 17-5/8" and mounting bracket width of 24-3/4".

  • Availability Of Kwikee 38 Series 24" Wide Step Without Electronics Of Motor
    Hello Nick, thanks for reaching out. We only offer the 24" wide Kwikee 38 series step as a complete assembly with the motor, gearbox and switch as part # LC3723383. Sadly we do not offer the single step by itself without electronics or motor. You may want to try reaching out to Lippert (they make Kwikee steps) directly to see if they can provide one. Otherwise the only option will be the complete assembly. If you are wanting to replace your 38 series step with a manual fold-down step,...

  • IS The Kwikee 3711363 A Good Replacement For A Kwikee 3711161
    I wasn't able to find a 3711161 but I was able to find the Kwikee # LC3711361, which is a 26 series RV step. 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. That being said, both of these are the same step, but with different equipment included with them. The # LC3711363 is the complete...

  • How to Pick Out Replacement Motor for RV Steps
    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...

  • Replacement Parts for Kwikee Series 28 Electric RV Steps For Complete Setup
    For your Lippert Series 26 step, I recommend the Lippert Components Kwikee Step power switch and door kit # LC369311 and then using controller # LC379146. Then you will also add the Lippert Components Kwikee Step Replacement Light # LC379414. This will work the single step # LC3747451 which comes with gears and motor only. If you are unsure of the current gear box and motor, then you would use the complete kit # LC379769.

    The Replacement Step, Motor, and Switch for Kwikee RV Electric Steps - 28 Series - 23-5/8" Wide # LC3747451 isn't going to include the control unit # LC379146 so as long as your current one is operational you can just reuse it with this new step. If not then you can order the Kwikee Electric RV Step Complete Assembly - Single - 28 Series - 23-5/8" Wide # LC3747453 which will come with everything you need.

This motor will work with Kwikee steps manufactured from 1999-2006, and also includes the mounting plate, 2-wire plug, and installation hardware.

  • Comparing Kwikee Lippert # LC3474453 VS # LC3747451
    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.

  • Recommendations for Adding Step for Easier Access on 2005 GMC Envoy
    I have a really great option for adding a step to allow for easier access into your 2005 GMC Envoy, however I don't think the Kwikee Electric RV Step # LC3747451 that you referenced is going to work well. It's going to require an awful lot of modification to the Envoy, with the addition of having to wire it up to the battery for power. I don't think there's going to be enough mounting space under the vehicle for the brackets, either. A much better option is going to be with a simple but...
