I'am looking at the Dexter axle #9

http://i.b5z.net/i/u/1080235/f/Torfl...ation_4-04.pdf

and they have 3 types of axle brackets-- low profile,high profile and side mount. Whats the advantage of the high profile over the low profile besides making the axle sit higher? (Going to replace my axle on my 13' Scamp)

As I understand the choices, the side mount hanger isn't really a different bracket welded to the axle, it's an extra bracket welded to the frame so the axle's bracket can bolt to it. It adds 0.25" to the high so the side mount bracket is presumably 1/4" thick.

The high profile option just extends the bracket higher above the the point where the arm pivots; that would provide a higher ride height (the trailer sits higher on the same axle), and may in some cases be useful if the square axle tube which runs across the trailer needs to clear something under the trailer floor. It would make sense to me to order high profile rather than using a separate spacer or extreme down arm angle, if the height were required, but I would not make the trailer sit any higher than necessary.

If you look at page 3 of the complete catalog segment for 1000-2200 lb axles or the fourth page (labeled as page 13) of the Torflex information document, you'll see the three choices.
  • In the low profile, the top of the bracket is folded right down on top of the axle tube.
  • The high-profile bracket extends higher, is folded to go across under the frame, and then bends down again to meet the axle tube for support
  • Either bracket can be bolted to the side mount hanger, which is in turn welded to the frame of the trailer; without the side mount hanger, the axle's brackets are welded or top-bolted directly to the frame.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

I now understand the photo better as I look at it. I also think that the high profile bracket would be much stronger than the low profile.

I had noticed earlier that the low profile bracket is "one-sided" - it's just an inverted "L" shape. The high-profile (and the similar AL-KO product) connects the horizontal part of the bracket to the axle tube on both edges, in an inverted "U" shape. The "U" is necessary in the high-profile or the bracket will bend under the vertical load of the axle, but it looks to me like the low-profile is probably fine, because the horizontal part is right down on the axle tube, so only the torque due to the arm length is a concern - the same torque that is tearing apart improperly installed AL-KO axles in some Scamps, by the way.

Brian, I've lost track - has ALKO or Scamp acknowledged a problem and/or offered a fix on the axle failures? Guess they are only happening on the 19' (5vr) unit, right?

As far as I know, the 5vr is the only one having the problem, but it might be a wakeup call for all Scamp owners to check the welds on the axles...no matter what year. I consider it to be one of those "maintenance" issues.... something to check.

Hello, I just purchased an axle from redneck trailer supply for my 1980 13' and it looks great. It is a 2,000 lb. 4 on 4 bolt pattern with a 22.5 down angle. It has a 63" hub face with high profile brackets and 49 1/2" outside of the bracket measurements. also, the brackets on mine are turned around so that the longer flat face of the bracket faces out. I think I paid something around 160.00 with out shipping. I hope this helps!

I have a 84 13' I need to put a axle in.
Original scamp axle is leading arm, scamp recommends trailing arm now and so does Dexter . Did you put a trailing arm axle in? If you put a trailing arm axle in I would like to see some pictures of your install. Also I just plan on cutting of the axle arms on the outside of the frame rails and leave the inside part. Because a have to relocate the axle foreward on the frame to a trailing arm axle to be correct.------- see photo

Whoops- - -don't cut there! You are going to have to remove the complete old axle. If you cut there you will find out how the old axle was made!!! ( plus, a danger of fire, not even mentioning the stink of burning rubber!!!) Pull up the Dexter website and take a look how the axles are built. Larry

I thought I would use a sawsall, should go very quick. I don't care if it gets ruined ---It's Shot anyway. Just need to cut off the ends. Leaving the center part on the trailer. New axle will be farther forward.

you could retire trying to cut through the axle stub with a sawzal. I just changed out my axle on the trillium. mine was so froze up it bent the frame instead of flexing...

As I understand the discussion to date, this was a Scamp installation error, which they are resolving with individual customers. There is no indication that there is anything defective about the AL-KO axles.

Well, I still have not installed it because I'm undecided as to how high I want the trailer to sit. Mine is also a leading arm setup and to turn it around to be a trailing arm system, I would have to "fill" in the spot where the current axle sits with small sections of rectangle tube so that the axle brackets had something to sit on ( I think ). Right now my axle is drooping so low that the axle spindle is probably at a 30 degree up angle and of course I ordered it with a 22-1/2 down which would create a "big" lift as it is. So I may just go back with the original setup which of course would be much easier, less work and not too much lift. But being as I would like to take the trailer off highway, I may just need to lift it anyway. We'll see.

I'm sorry, I don't think any additional tubing would be necessary since the brackets would be toward the front now.
