Axle riser kit adds 3-1/2" of clearance for your torsion axle-equipped trailer. Riser channels install between axle and trailer frame to increase deck ride height. Designed for square, 3,500-lb axles only.


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.

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.


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


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.

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


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


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.


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.


These riser worked perfect and easy to install. Very strong and well built.


The parts arrived super-fast!!! All of the parts were included in the package. Thank you!


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.

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 ??


The kit is very well made and coated with a heavy epoxy, should last longer than the trailer! Fits exactly, nuts and bolts washers included... well worth the money, I would highly reccomend for anyone wanting to increase under body clearance and got to a larger wheel size. I went from a 13" to a 14" and could have run a 15" but 14" works the best for my trailer!!


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.


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!

The Etrailer crew was helpfuk, the part fit perfectly and has flawlessly performed. Adding the lift made a tremendous difference for us.


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!


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


Lift kit risers fit perfectly on my 2018 Flagstaff E-PRO 19fbs Camper. it has the Dexter square tube axle,3,500# Un bolted old bolts and bolted on the new risers myself in a couple hours. the extra ground clearance is really nice! Thanks etrailer!!!


A very good kit! My challenge was getting my older Jayco Jay Feather Sport to come apart. Once that was done, the actual installation was smooth sailing. The hardware is good and was up to task at 120 ft lbs of torque.
I don’t have to worry about dragging my black water tank anymore!


We bought a brand new 19ft Geo Pro trailer and we wanted a bit more clearance. This rise kit was perfect. My husband even installed it himself. Would definitely recommend.


The service was excellent! As far as the product is concerned, I won’t know until it’s installed within the next three weeks.


Solid product easy to install. Timely delivery and all needed hardware was included.


Works great, perfect heights.


Received quickly and fits just right on our R-Pod.
