Video Transcript for Review of Lippert Trailer Leaf Spring Suspension - Axle Risers Single Square Torsion Axle - LC382741

Hi, everybody. Andy here with Let's take a brief look at this Axle Riser Kit for your Single Square Torsion Axle. This lift kit is going to raise your trailer frame to provide three and a half inches of additional clearance between your trailer frame and axle. Now, this kit is designed for use on trailers with a single square torsion axle with a 3,500 pound capacity. And this is compatible with side mounted torsion axle mounting brackets.

And this kit includes everything that you see here on the table before me. You're going to receive two axle riser channels, and all the mounting hardware that you need for a successful install. Let me go ahead and just give you some overall measurements to give you the further confidence that this is going to work for you. So looking at our mounting holes, measuring center to center, as you can see, we are sitting right at seven and seven eights inches on center. And there's your three and a half inches.

And the overall length, in case you are wondering, we're sitting right at 11 inches. Well, that's going to wrap up our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

We purchased the 3 1/2" chassis lift kit to improve durability of a highly modified/upgraded A-liner Scout Lite. It was a smooth install. Heeded some earlier advice about leaving the toungue attached to the truck. Good safety tip. The lift is impressive. We went from 14" wheels and tires to 15" wheels and Falken AT3's. Ground clearance is 12" now. This is our third or fourth purchase from etrailer. All items and upgrades to vehicles and trailers were easy with their videos. You won't be disappointed.


The blocks are awesome. Solid. Install was easy.

Only dropped one star because the mounting hardware was incomplete. Missing several bolts and washers. A trip to the hardware store remedied that, but was inconvenient.


The trailer lift kit worked perfect..
modifications whatsoever and quick service


Fit well, I did have to use a step up reamer to increase the hole diameter on my trailer frame to accomodate the supplied bolts. Otherwise it fit up well and increased the axle to frame clearance. Next step, increase rim and rubber for road clearance.



Lift blocks have been solid! The increase in trailer ride height make pulling the popup in and out of the garage easier. Less issues with tilt and scraping for sure. Happy to have the addition


Kit fit perfect.It took about 1 hour to install.Anybody should be able to do it yourself with a few basic tools and a floor jack.Also the price was lower than anybody else.Shipping was very fast.Will use etrailer for all my trailer parts.


Worked just like I hoped it would and allowing us to go from 235 75 15 tires and wheels up to 245 75 17 tires and wheels to match are Jeep.


This kit fit perfect and installation was straightforward and simple. Really added the extra height to my pop-up camper!


The 3.5 inch lift get lifted my trailer up and levelled it out for better towing . was fairly easy to install and was done in less than a hr . one bolt on each side was a little difficult to tighten as the spindle swing arm on the axel was in the way.
Very satisfied. 3.5 inches was plenty of lift


Fit up was perfect for my R-Pod 177 and provided the additional ground clearance that I needed.


The product came as promised. It is very good quality and support on the company website is very good. I do wish it had shipped with recommended torque settings for instalation.


The lift kit came and I installed it by myself. I’m 73 years old and I thought it was very easy. The hardest part was removing the old bolts but with a little penetrating fluid they came right off. They fit perfectly and lifted my trailer 3.5 in. I am very pleased with your product as I take my trailer off road and this will give me the clearance to do this without damage


It looked like it is well put together. It installed just as it was supposed to. I left the camper connected to my tow vehicle for added support and I only did one side at a time for added safety. It took a little longer but I felt safer. Thank you for a great product.



3800km trip over some not so nice roads without an issue.


Perfect fit for a 2020 nobo by forest river I diamond style single axle east to installation Would highly recommend if you’re having problems with clearance or you have a bigger truck I have a 2018 Dodge Cummins on 37 and it looks A lot better behind it an it has a lot better clearance ??


Fantastic assembly. Didn't take long to arrive and easy installation.. first time ever doing anything like this and it went better then I expected.


I've had these lift blocks for over a year now and have been very satisfied with them. Product looks well built, was easy to instal, and came with nice grade 8 hardware. The added lift allowed me to put larger wheels and tires on my trailer. So far I've towed my Aliner Ranger 12, with these lift blocks installed, over 5k miles through all kinds of weather and off road and have had no reason to be concerned about them at all. My only complaint is that it took a while to receive them after ordering. I think Etrailer was waiting for a new shipment of them at the time.

Perfectly. I dont worry about it or even think about it. It just does what its supposed to do. Thats exactly what I wanted.


Quick delivery - excellent customer service, now we can take our trailer off-road


Worked great, had to drill new holes because I had an older axle, which I knew going in, but it worked great


Did exactly what I wanted


Ordered for 2018 R-Pod. The bracket did not fit. I had to modify the brackets to get them to fit our camper.

You mentioned that you needed to modify the brackets to make it fit and I wanted to see if you could explain in more detail what you meant.


So glad I bought this! I have a 1999 Starcraft pop up camper that I needed to lift. I did need to match drill the holes for the generous bolts provided. This was accomplished with very little effort with a stepped drill bit. 3 1/2” of lift in less than a half hour (Note: I do have a lift).



Fantastic so far. I actually forgot I did it. I used it all last summer.


Gave the perfect lift to my cargo trailer conversion. It was an easy installation, and I feel good about it being done the right way.



Perfect solution!


It's a little bit unfair to the kit for me to be reviewing it. I ordered it knowing it was not designed exactly for my setup, but figured it would be faster than fabbing my own.

I have an Al-Ko axle on a popup tent trailer. I knew the bolt holes from this kit would probably not line up perfectly but I hoped I could use the kit with slight modifications. I was unable to find a kit specifically for the Al-Ko axle.

The bolt holes on the purchased kit are about 9-inches on center. The bolt holes for the Al-Ko axle and trailer frame, for my setup, are about 6-1/4 inches on center. Otherwise the arrangement of the axle relative to the trailer frame is identical (simple rectangular abutment). It took me a few tries to get everything perfectly aligned, but it seems to be working now. I should have pulled out my micrometer to take exact measurements.

The included bolts are too big for the frame and axle holes, so I used some grade 8 that I already had on hand.

The kit itself is simple and relatively difficult to get wrong. The welds were clean. The cuts were clean, and the protective paint job was adequate.


I’ve had this on my trailer for about a year now and have zero complaints.
Install was very easy and there was no change in axel alignment.
Installing this lift made a big difference when pulling my trailer loaded and a huge difference when pulling empty.
The factory paint seemed alright but I went ahead and added a few more layers of paint just for added protection from the salt.


These lift blocks for this trailer are great! It raised my trailer to a nice height and it was and easy install! Best method would be lift trailer and place on jack stands on all four corners. Two people makes it a 30-45 min swap!


Easy to install and looks great. Needed more axle clearance to install load range D tires and these worked perfect.
