Just finished installing the LCI Solid Step Lift Assist accessory on my 30" Solid Step Quad stair setup. I should have just bought these already installed on my stairs, since I had to replace the top hinged section and the latching assemblies. Installation was not that bad and now my wife can open and close the stairs all by her self. Glad I bought this lift assist setup, but like I said I wish I just bought this way from the start. 666671

Easy install, Well built. I would recommend taking the existing steps off the floor hinge plate first, then remove the existing plate from your RV floor. Install the new hinge plate into door opening with the two positioning screws through the holes while the plate is in the open position, then bolt your steps onto new plate. If you do it like the instructions it will be difficult to get the whole assembly into door opening and it's easier to do yourself this way. The lift assist sure makes raising and lowering the Solidsteps super easy. 696785

The SolidStep fold down step are very well made and I am impressed with the quality. Ordering from etrailer was a breeze and delivery was quick. However, UPS did not handle the carton very well, there were parts that poked through the carton, it was barely holding together and the bags of hardware/screws included had broken open and were scattered in the carton. It was a flimsy carton for shipping an items of that weight and there was one part that was slightly bent which didn't matter as the lift assist replaced it anyway. Installation was not hard and I was able to complete the steps, lift assist, and handrail in a couple of hours. There were a couple of things I was disappointed in, several loose bolts and screws, and the left side rail only had half the necessary holes for mounting the handrail on the left side. I had to drill the rest of the holes to complete the handrail install. We are very happy with the new steps and would definitely buy again. 827691

Really makes it easy to raise and lower quad solid steps. The install was fairly easy. I was missing the hardware mentioned in the instructions, but was able to reuse the hardware from the existing solid steps. I had some screws that were better for mounting the bracket for air arm. Surprised that both air arms were included in my kit. This is really a heavy duty kit that is made to last. My back is really happy with this purchase. 663314

  • Lift Assist Kit for Lippert Solid Step RV Steps
    We have the SolidStep Lift Assist Kit for 26" to 29" Wide RV Door Frames # LC733937 or the SolidStep Lift Assist Kit for 30" to 36" RV Doors # LC733939. This lift is designed to make it easy to lift and lower these steps. We had a training where they showed us you can lift the stairs with a couple of fingers using this lift, so it is a really nice option to add for ease of use. This is a new product, but there is not a waiting list we can put your name on. When you order either of...

  • Installation of SolidStep Lift Assist Kit
    Though the SolidStep Lift Assist Kit # LC733939 does not have individual instructions, it will be the same as installing the strut on SolidSteps that have the Lift Assist. I have attached a cutout of those instructions for you which is the process you will need to follow for this assist kit. I will also copy those directions below as well as send you a link. The SolidStep Lift Assist Kit # LC733939 will work with the SolidStep Manual Fold-Down Steps # LC678028, # LC678031, # LC791573....

  • Determining Compatibility of the SolidStep Lift Assist Kit
    There are two different SolidStep Lift Assist Kits, part # LC733937 and part # LC733939. In order to confirm either of these will work for you, you will need to go though the purchase verification process outlined by Lippert. See Below: The Lift Assist Upgrade Kit will ONLY work with triple and quad SolidStep 3.0 (Fig.1). The Lift Assist will NOT work with double SolidStep 3.0 or with previous versions of SolidStep - including SolidStep Gen 2 (Fig.2). Lift Assist will not work with any...

  • Stuck Gas Struts on Lippert SolidStep Lift Assist
    I have contacted Lippert about stuck gas struts before with their SolidStep Lift Assist Kit for 30" to 36" RV Doors # LC733939 and they have said that there is not a quality issue with their struts. The only thing they have told me is that the majority of the time when the struts are stuck it is because of the installation not being proper, and as such there is some type of interference not allowing the strut to work as it is intended. They have also told me it is possible it could be the...

  • How Much Wall Space Does Lippert LC733939 Solid Step Lift Assist Take
    According to the installation instructions for the # LC7333939, before the installation, the door trim on that side of the door will need to be removed up to a height of 29-1/2 inches. The lift assist bracket is meant to butt up against the outside of the door jamb, and is 2-3/8 inches wide so you'll need at least 2-3/8 inches of free space between the outside edge of the door jamb and the wall you speak of. I've provided a diagram showing this dimension.

  • How Far Does Lift Assist Stick Out Inside Door
    I actually just contacted Lippert about this not long ago, and they told me the SolidStep Lift Assist Kit for 30" to 36" RV Doors # LC733939 will extend approximately 4-1/2" to 5" inside the door. So that's not something I would classify as a shin buster, but definitely something you may want to be cognizant of if there is open space leading up to your door. That said, the small risk of potentially contacting the lift assist is well worth it due to how much easier it is to use your...

  • Troubleshooting Struts on Lift Assist Stuck
    I reached out to Lippert concerning the struts being stuck on your SolidStep Lift Assist Kit # LC733939 and they told me that the first thing they recommend doing is simply ensuring it is installed correctly, as per the linked installation instructions, which I recommend taking a look at. The strut could be bad, but they have seen in the past that an incorrect install can lead to the issue you are having.

  • Does The Door Trim Have to Be Removed To Install SolidStep Lift Assist Kit RV Doors LC733939
    The mounting bracket of the SolidStep Lift Assist Kit for 30" to 36" RV Doors part # LC733939 basically installs 1/4" away from the door jamb on the interior wall. It does need to be flush with the door jamb so if there is a piece of door trim keeping the bracket from being level with the door jamb then it needs to be removed. The 1/4" measurement is from the installation instructions for the lift assist kit itself which I have sent you in a separate email. The 1/4” gap will allow the rotating...

I have added photos from the instructions of these lift assist kits, which includes instructions on how to tell the correct kit if you have a SolidStep 3.0 already installed on your trailer.

  • Recommended Lippert SolidStep for a 2014 Keystone Montana 3402RL
    I am not sure who you spoke with at Lippert but what they told you about using the 26" wide SolidStep # LC791574 was incorrect. When I spoke with my contact he said that whether you have the 29-3/8" or 28-1/4" wide frame you want to use the 30" SolidStep # LC791575 that we referenced in a previous answer. Reason being that there is no SolidStep for a 29" wide door frame so you simply round up. When the SolidStep first came out there was conflicting information regarding fits but I believe...

  • Will SolidStep Lift Assist Kit Fit a 2020 Keystone Passport GT Series Trailer
    I believe you are saying that your 2020 Keystone Passport GT Series has a Lippert SolidStep. If this is the case then the Lift Assist Kit # LC733937 will work if your door frame is 26" to 29" wide. If your door frame is 30" to 36" wide then you need part # LC733939 instead.

  • Do SolidStep Manual Fold-Down Steps Have a Lift Assist
    I can see where the confusion might come in, but the SolidStep Manual Fold-Down Steps # LC678031 actually only weigh about 50 lbs, the 400 lbs you were referencing is actually the weight capacity of the steps. They do not come with a lift assist but one can be added to the steps, the SolidStep Lift Assist Kit for 30" to 36" RV Doors # LC733939 so you can easily lift and lower your steps. In regards to your other question, there is a locking mechanism that will keep the steps in place...

  • Fold Down Steps For a 2013 Forset River Rockwood Signature Ultra Lite 8281WS
    From my research and experience installing steps on fifth wheel campers your 2013 Forest River Rockwood Signature Ultra Lite Fifth Wheel the door opening should be 30" to 36". If I am correct I recommend SolidStep Manual Fold-Down Steps for 30" to 36" Wide RV Door Frames - Quad - Aluminum Item # LC791575. Most fifth wheel campers sit a little higher. Having the fourth step ensures the bottom step is not too far from the ground. The steps have adjustable legs for un-level terrain so you...

  • Recommended Hand Rail for Lippert SolidStep Fold Down RV Steps
    The Lippert SolidStep # LC791575 you referenced will use the Lippert Entry Assist Handrail for SolidStep Manual RV Steps # LC799640. You may also want to consider the SolidStep Lift Assist Kit for 30" to 36" RV Doors # LC733939 to make raising and lowering easier.

  • Correct SolidStep Manual Fold-Down Steps for a 2012 CrossRoads Cruiser
    For your 2012 CrossRoads Cruiser, the correct SolidStep Manual Fold-Down Step is going to be part # LC678044. According to Lippert, once you measure your doorway width you then need to round up to the next even number which in your case is 30. The threshold of this step is then 27" - 36" which is perfect for your 32" doorway height. The SolidStep Manual Fold-Down Steps are a very popular upgrade for the conventional pull out steps so I am sure you will be happy with them. They have adjustable...
