Features to know about

Smooth, Safe Entry Every Time: Electric Motor Extends Steps on Command

These Kwikee 40 Series electric steps automatically extend and retract through the included switch kit, giving you steady access at the press of a button. The 12V motor works with a gearbox for smooth, reliable motion and retracts safely if it strikes an obstacle. Each of the two steps measures 24" wide x 11-1/8" deep with an 8-1/4" rise, giving you a comfortable, stair-like feel as you step in and out.

Confident Footing Day or Night: Non-Slip Tread with Amber Light

When you’re climbing in after dark or in wet weather, the non-slip tread and reflective strips make every step easy to see and secure. The amber incandescent light shines directly on the step surface, so you can clearly spot your footing and avoid missteps.

Built to Handle the Elements: Powder-Coated Steel and Weatherproof Wiring

Made from sturdy, powder-coated steel with solid steel drive rods and stainless steel bushings, this step assembly resists rust and flex. The weatherproof wiring and air-pressed rivets at the pivot points keep the mechanism strong and reliable through years of outdoor use.

Ready for Everyday Use: 300 lb Capacity with Compact Fold-Up

When retracted, the steps fold to a 6-3/4" height under the doorway, staying clear of road debris. Fully extended, they provide a stable 17-1/4" height and can hold up to 300 lbs without wobbling. It’s a simple, solid solution for anyone who wants dependable steps that move with a switch instead of manual lifting.

Straightforward Replacement Fit: 24-1/4" Mounting Plate and 20-1/2" Bolt Pattern

This assembly includes the steps, motor, and switch kit, designed to replace original Kwikee 40 Series units. The mounting plate measures 24-1/4" wide x 14-5/8" deep with a 20-1/2" by 12-7/8" bolt pattern, ready to line up with existing holes for a clean installation and a factory-fit finish.

Etrailer was easy to shop online, great price and fast shipping I ordered my kwikee step on Sunday and it was at my house on Tuesday. The installation was easy remove and replace using a small jack to hold the step in position. I did have an issue with the wire going to the motor, the retainer clip somehow was broken on arrival and would not hold the connector to the motor but a zip tie took care of that problem. The steps did not come with new magnetic switch so will have to order one separately the one on my rv was not working. Overall great shopping experience. Will shop here in the future.

The steps have worked perfectly and the installation was straight forward.The steps arrived fast and in like new condition. I look forward to doing business with your company in the future.

by: Rodney 06/21/2020

Bolt-on replacement. Some splicing required, mostly because whoever installed the last one added some unnecessary lights.

A challenge to lift into place, but I used a hydraulic auto jack to assist.

Only problem, the high current shutoff feature (when current increases, the control system shuts off the motor because increased current should mean the step reached the end of its travel) stops the steps prematurely. I'm hoping that as the steps wear in, this will stop happening. Until then, I need to provide a slight force upward when the steps retract to get them all the way up.

As a follow-up, no change. Step works but still stops prematurely.

Perfectly! Still taking feet, one or two at a time.

by: Robert 05/26/2023

These steps will be a perfect match to the original and will be installing them soon. Looking to to replacing the bent up, unrepairable and unsafe steps. Thank you ETRAILER for your expertise.

The steps have been working flawlessly and we love the automatic stow feature when going into gear. Great product!

by: Daniel 09/14/2022

After injury and age, getting in and out of a leveled RV is one high step. Having these steps reliably and sturdily come out each and very time needed is a big deal. I installed this on an older RV and for folks that have older RV's please note; the micro-switches in the the door frame are opposite of what are needed for today's control logic. As a result, I added a "Reversing relay" to create the proper signal from the door to have the steps operate as designed.

Fantastic! Still works well. As I get older with weaker knees and hips, makes it possible to get in and out of the RV easier.

I ordered electric steps in Feb and it was April 5th when I opened the box only to find that it was broken during shipping . I called that day and sent pics of the damage . etrailer said they would send replacement and it arrived today . I've never had such quick response. I want to thank you guys for handling this for me and I'll recommend yall to everyone that I can . Thanks again

When we finally got around to getting someone to install the steps, they were not the right ones to fit even though we were led to believe they were. All new holes had to be drilled & after they were installed we can hardly get up & down the top step. It is much too far from that step to the motor home. We had to devise a piece of wood to secure to the top step when we’re out so we don’t have to climb so far! Also the steps do not go in flush with the motor home as they should. It had been so long since they were purchased & we figured there was nothing we could do once installed but they are not right & may cause a problem when we go to sell the unit.

by: Allan 09/17/2019

Good product, it was sometime before I had time to install it but all went well. It is such a relief knowing it is safe to step up or down. Thanks

After one year it has performed perfectly. I installed it myself as a complete unit

by: Lawrence 09/30/2022

Easy to find and order. Received in a very timely manner. Very happy with the product.

by: David 05/20/2023

I am 78 years old and removed the old step and installed the new one in about 4 hours. I have a 93 Safari that is in great shape and this makes it better.

How to Determine the Correct Replacement Steps for 2017 Winnebago Winnie
In order to determine which double steps to use with your 2017 Winnebago Winnie you will need to know the mounting bolt pattern of your current steps.

If you let me know what your mounting bolt pattern is I would be happy to make a recommendation for you; I've added a...

Troubleshooting Powered Steps on a 2008 Holiday Rambler that will Not Fully Extend or Retract
We don't carry the SCS/Frigette brand of steps so it's a little hard for me to troubleshoot the problem you are experiencing, but it sounds like the gears of the steps are jamming up which is preventing the steps from moving more than just a little bit. What I would recommend you do is get underneath it and inspect the gear assemblies to be sure there isn't anything stuck in the gears or that the gears themselves have been damaged. You might also check the condition of the wiring. A bad...

Recommended Heavy Duty Replacement for Kwikee Series Steps
If weight capacity is the primary concern then you will want to take a look at the SolidStep Manual Fold-Down Steps as there is not a heavy duty version of the Kwikee Series Steps. The Kwikee Series are almost all rated at 300 lbs whereas the SolidStep is rated at 400 lbs. This will be the best replacement for your Kwikee Series as they install in an odd fashion that most other manufacturers do not make replacements for. The SolidStep install in the doorway so the odd mounting of the Kwikee...
