Axle blocks for raising trailer

I'm looking at a new 5th wheel that unfortunately only comes with 15' wheels. I converted my current trailer to 16" wheels, but to allow for sufficient wheel well tire clearance, I had to weld a 2" square tube to the frame to raise the trailer.

Not really wanting to go through this process again I ran across a leveling kit using blocks above the axle. The product is made by trailerblocks.com. I would not need to raise more that 1 - 2".

These look like they are made very well and just wondering if any of you have used these.


  • This what I did to raise my E up 2ins also made a cross brace to help to stop sway.
  • You will be way ahead of the game by cutting the hangers off and welding the square tubing to the frame. Then re install the hangers with a 1 1/2” tube welded perpendicular to the frame from hanger to hanger. You accomplish the height issues along with the frame flex you will get when turning sharply.

    If the lower set of hanger holes will give you what you need you can put the X-factor on it also. I believe that all trailers need some kind of crossmembers on it.

    The correct-trac system will raise a couple inches, and may be a better option.

    I'm with you, Jerry. The Correct-Trac would be a =much= better alternative, IMO. Useful, too! :B

    The hangers are pretty flimsy to begin with, and the additional torque side to side might well be an issue. With that said, I did that on my current trailer but had 2" square tubing welded across the trailer from one hanger to the opposite side hanger. Just a lot of cost and trouble.

    the Correct Trac system looks interesting. Wonder if most shops are set up to do an alignment with it?
  • That's a lot of money for simple blocks with a hole and longer u-bolts.
