Thanks,
So a new 4,000 lb axle with 32 degree start down angle should provide a safe ride and keep our 40+ year old trailer from getting beat up...makes sense.
Great axle thread, ya'll.

The single axle 23 foot model started out with a 4000 pound axle rating, then changed to 4500 pounds and finally to 5000 pounds, depending on the year.

I will post those years once I get back to my office.

I did some repairs on a 2002 CCD Airstream and it came from the factory with Dexter axles and no shocks. Were the engineers asleep for that model?

Dexter engineers pushed for the "no" shock deal.

Finally, Airstream won the battle.

But, Dexter still refuses to put shock brackets on replacement axles.

That's why we have them made to the original specs.

There is some work in the mill, within Dexter, that we are aware of, to get that changed, even though at the moment it's in a very slow pace.

Andy, do you have pictures of the brackets that you have made to convert the Dexter axles to use shocks?

Photo's of shock brackets that we have made, for the Dexter axles.

They are the same as used by Henschen.

The steel plate is 1/4 inch thick.

The edge to be welded to the torsion arm, is 4 inches long.

The studs are from the Airstream supplier.

Andy, thanks for the picture. It appears that when welded on it is perpendicular to the torsion arm so that it rotates toward to front (when the torsion arm moves upward) so that it can use a horizontal shock.

For those axles that don't have a shock mount, it seems that one could be fabricated to attach to the four backing plate bolts, so that no weld would be required on the torsion arm. Having it attached to the torsion arm would be better, but I would be concerned about any warping caused from the weld. It is such a massive piece of steel that I don't think it would be much, but I wouldn't want a warranty voided, or any issues with such an important piece.

Reasonable welding will not hurt the rubber rods.

Henschen installed the shock brackets after the axles were assebled for years.

Never caused an issue.

As Andy points out the axles got heavier with experience which is he logical progression and follows the way many things are done in several fields. I was in small arms engineering and the weapons testing and evaluation field and the M16 has had over 500 "improvements" added to it 45 years and testing is underway at this time for a dozen more.

I suspect as someone pointed out they were pulled with passenger cars and weight was the enemy. Now with most folks using light trucks/SUVs with more capacity they were changed to make the interface.

The single axles at 5000 lbs is very interesting indeed.

Dexter will install shock brackets on axles built in Indiana, but not in Oklahoma.

I have a 1991 34' Limited with 2,800 pound factory axles that are pretty shot. Who could I talk to at Dexter about getting the proper replacement axle. I'd like to raise the height because I'm going to 16" wheels and my tow vehicle is a 3/4 ton 2000 Yukon XL. I've looked at http://dexteraxle.com/i/u/6149609/f/600-8K_Cat_1-12/2300-3500_Lbs_1-12.pdf and I don't see anything mentioned about shock mounts or axles other than the 22.5 degree down as the tallest-standing variety.

Steve,
As has been mentioned previously, Dexter's largest retail handler is Redneck Trailer Supplies. There is a Redneck location in Wichita. There are other retail handlers of Dexter axles, however. The Dexter option for shock brackets on a #10 axle is E 1501. It is not something that normal retail outlets know about. I would call Dexter support at 260-495-6000 and ask for Denise to make sure it is possible to get that option spec'd on your axle order. Dexter axles are not the only rubber torsion axles that will work for you.

You can get Al-Ko/Axis axles From Colin Hyde Trailer Restorations that can be spec'd with Henschen type mounting brackets and shock mounts already welded on.

You may also get Rockwell American Axles from Quality Trailer. Made in Texas. They have a bracket that is similar to the original Henschen bracket. Drilling is not typically required. They do offer 35 degree down starting angle and many other options like extra long shielded brake wires. They do not have a shock bracket option.

Having seen your thread and the skills you have, I would suggest cutting the old shock brackets off of the old axle and welding them on the new axles.

I'm attaching a few Dexter drawings of their Airstream shock mount.
