Features to know about

Automatic Entry Made Easy: Step Extends and Retracts with the Door

The Kwikee Electric RV Step Complete Assembly - 33 Series takes all the effort out of stepping in and out. The 12V motor and control unit automatically extend the 28-1/8" wide by 10-3/4" deep step when the door opens and retract it when the door closes. A built-in switch kit lets you keep the step locked out when parked, so it stays ready even if the door is shut.

Safe to Use Day or Night: Reflective, Non-Slip Step Surface with Light

A bright amber incandescent light illuminates the step, while reflective strips make it easy to see in low light. The non-slip tread gives you solid footing in rain or dust. With an 8" drop/rise and sturdy, powder-coated steel construction rated for 300 lbs, it feels just as stable as fixed stairs.

Built for Real-World Abuse: Steel Frame with Durable Drive Components

These steps are proven tough—built from powder-coated steel with solid steel drive rods, stainless steel bushings, and air-pressed rivets at every pivot point. The 33 Series design holds up to daily use, which is why people install them on heavy-duty service rigs and emergency vehicles that take constant wear.

Smart Safety Features for Everyday Protection

The integrated safety system automatically retracts the step if it strikes an obstacle, and an ignition override pulls it in when the engine starts so you never drive off with it extended. Weatherproof wiring and a sealed design keep the motor and control unit protected from the elements for long-term reliability.

Complete Assembly for Direct Replacement

This package includes everything you need to replace an existing Series 33 setup—motor, control unit, switch kit, light, 4-way plug, and 4-way pigtail. The mounting plate measures 26-7/8" wide x 9-1/4" deep with a 23-5/8" x 6" bolt pattern, so it lines up with existing holes for straightforward installation.

Metal outriggers for RV step installation, providing extension brackets for mounting Kwikee electric steps to various RV chassis widths.

We use this on our ambulance and it has performed tremendously. The only reason we had to replace it was that is was damaged during a call.

Great product and fast shipping.

We have used this exact step before, we have installed at least a dozen or so in the past. It is a good product; it does take the abuse we see them put thru. We install them on emergency vehicles all the time.

I have a 2003 Chinook Concourse and the 33 Series Step fits perfectly.
I am very happy with this purchase.

  • Replacement For Kwikee 33 Series Steps
    So we can get you a replacement for your Kwikee 33 Series steps, though I verified with Lippert (who manufactures the Kwikee steps) that the assembly (frame) by itself is not available as a replacement, as you can see by the cut out I added below.
