IMy experience has been that shocks are not necessary with any kind of torsion axles. I ran my new install with and without shocks for many miles to determine this.
I am not sure what AS was after when they decided to put shocks on a rubber torsion axle, but it definitely wasn't ride quality.

Some of our local trailer companies stock them since they are becoming very popular on horse trailers and many new highline 5er's are coming standard with them. Of course everyone of my trailer breakdowns have occured after business hours on a Saturday so it doesn't matter if they are piled high behind the "Closed" sign

I agree on regular maintance of the brakes but a deciding against a no maintance hub for that purpose akin to designing a trailer that will suffer from rear end seperation just so the toilet seal will be replaced on a regular basis

I installed a set of Dexter's last year on my 78'. I have the #11 axle with the disc brakes and I know for a fact that the original Alcoa rims will not fit with the #11 axle and disc brakes. It is close, but not close enough. I can not say for a fact, but I would guess that if you purchased a #10 axle with disc brakes, they may fit. The new rotors that I have were larger than the original rotors that Airstream installed. My decision came down to cost. For $200 more (delivered) than the cost of the standard electric brakes made by Henschen, I got 2 alxes with disc brakes and a E/H acutator. I will admit that I did have to drill (4) extra holes in the mounting bracket., and enlarge the opening a little. One set of the bolt holes lines up perfectly. If you are going to tackle a job like putting new alxes on your rig, you probably can drill some holes. You could also save a bunch of money if you don't mind electric brakes. I also made the mistake with the rims. I had to purchase 4 new rims becasue the originals did not fit over the larger Dexters discs. I was able to sell my (4) old rims for the same price as I had to pay for (4) new rims that fit. If you want to keep your old Alcoa rims, you may do some research on the #10 axle, or fork over the big $ for the Henschens.

yeah erock, that was the info i had too.

given the o.p. has a 34 ft trailer going with the smaller diameter isn't a great idea.

there is clearly a used market for the 5 spoke alcoas, i've got 9 of them!

cheers

I talked to Dexter about this. They say they downsize the general hardware throughout the axle when then produce a lighter rated axle. Since the TorqueFlex axles do not have any type of equalization between the axles they are afraid that if the trailer load was placed on one axle, going over a bump, that the axle would bend.

Having just resently installed Henschen axles and having had serious brake problems with their Chinese components if I were to do it again I would order Henschen axles without brakes and hubs and install Dexters brakes.

I assume if you could ever get beyound the Customer Service people at dexter they would make a system up using heavier axles and just insert the correct rated rubber rods in the tubes.

Sorry, I wasn't thinking of the new style rims. My Overlander's weel did fit, and so did the wheels of all the 70's trailers, both steel and alloy.
Good to know that the spoke wheels don't fit.
Are there other known wheel styles that do not fit over Dexter's big brakes?

Unfortunately, the #10 axle doesn't come with the 6-bolt HD hubs any longer. Dexter is telling us that a #11 axle is required to get the 6-bolt hub with the 5-bolt brake flange.
This could be a problem for smaller vintage units in the future, like a 70's double axle Safari for instance. The smaller units like Safaris, TradeWinds, and Overlanders require 2600lb to 3200lb axles, while the #11 axle has a minimum capacity of 3400lbs. It might be best to order the Henschen axle set for these, as that manufacturer makes the light duty axle with the heavy duty hubs. It simply is a better fit for these types of trailers.

well that's an interesting turn of events. I thought that the axle's rating was simply a function of the length of the rubber rods, and that they could be de-rated simply by cutting the rods down to a shorter length. Seems odd that they would have these sorts of restrictions, when each one is made to order. (?)

I know. Weird. For a while, we could order the Dexter #10 axles in just about any weight rating with never lube hubs only. Now, they no longer offer that.
I have a message in to Dexter engineering, hoping to get first hand info on the subject.
btw. we installed a set of Dexter disc brake axles just this afternoon, and it went really well, as usual.
The #11 axle requires the axle plate cutout to be enlarged slightly, and one of the holes( the front one in our case) has to be re-drilled. Installation took about 30min per axle, preparations beforehand about 1.5 hours, with coffee breaks.

Nice work Uwe!

Any idea which Dexter axle came on our AS? I believe they are rated at 3800#.

I imagine that new discs will be in our future....as soon as the drum brakes are gone, will be running the Safari to Orange, just a warning.

Thing is, they still make smaller dual axle trailers that aren't much heavier (if at all) than their vintage counterparts. What do they use on those? did they go back to Henschens? I suppose if you call up Dexter and say, "yes, I'd like 1,000 axles, please", they'll do whatever you want.
