Tag axle shocks question..

Well the shocks I ordered from Mor/Ryde arrived and their just someone's old shocks repainted..end threads are rusty and bunged up..

Am I wrong but aren't shocks supposed to be extended until vehicle weight pushes down on them to compress them ?These shocks extend hard but collapse easily and stay collesped.Just like my 12 year old ones...

My coach is a 1999 F53 w/tag, 37' Fleetwood Pace Arrow Vision..
Thanks, Ted O.

I'm dissapointed that no one on this forum has taken the time to reply to my thread.. Am I the only one that has a tag axle that needs shocks ?

Thanks for the reply. Mor/Ryde called this morning and said the shocks are no longer made and these were sitting in the warehouse for some time, their sending me 2 more that may be better appearing , but they assured me these were never used..

Only gas pressurized shocks will extend with no load. A regular shock will be stiff to move but will stay at whatever length you put it at.

Agree & good luck

Last post is correct on shock extensions.
I took Bilstein gas shocks off and they did want to extend the full length aggressively. The replacement shocks were made by Koni, are oil filled, and did not try to extend although they were very stiff to move. I don't know if Koni makes a replacement shock for you, but they are over and above the average RV shock in performance.

Koni is definitely the best and they would be my first choice is I ever had to replace shocks.

If anyone still has the problem with Mor Ryde tag axle shock availability, I did a trial and error test and came up with the following: Monroe air shocks, their part number MA739 is a direct bolt-in and you can vary the load on the tag axle by the amount of air pressure you apply to them. It appears that 40-45 psi is in my comfort zone in that the tires do not skid during braking and they apply about 300 pounds of lift (150 pounds per shock) to the chassis at that pressure. Should you be carrying extra weight, like a full fuel tank, fresh water, black water, grey water, etc. you can always add 10-20 more psi to the shocks to make up for the extra weight and Rock Auto has them on line, delivered to you for around $75. Pretty good deal I think and an easy fix. After I get back from Quartzsite next February, I will post my results again.

They did the trick for 2 trips, now the original problem is back . I'm pretty sure one shock is shot,, Thanks Big Dan, I'll get a set of them , I like the idea of them being adjustable also.. Ted

On a 2000 37' V-10 National Tropical with tag axle, I removed the original OEM shocks and replace them with Monroe's Gas-Magnum RV shocks. Same Mor Ryde axle I would assume. Anyway, was VERY pleased with their performance and ride. They also were a very reasonable priced alternative to more expensive (and questionable improvement) designer shocks.

Optionally, you can plumb the two shocks individually to adjust side-to-side loading, which in my case was a requirement in that my coach is heavier on the drivers side at all times, regardless of how much liquids I am carrying. Now I can balance it out a little without too much hassle, just adding a little air to the left rear shock. The individual air lines and fittings cost about $15 for the pair. I think that is a good investment if you have an unballanced rig.

No, they are not the same tag axle in that the early ones (1990-1992 or so) require helper springs on the outside of the shocks to pre-load the shocks in order to get the proper balance between the tag axle wheel and the driving wheels, and without these helper springs, the tag axle wheels will skid when you apply the brakes, even on dry asphalt due to not carrying enough load to prevent them from skidding. It also says that the tag axle is not carrying the load it was designed to carry, thus loading the driving wheels with more than they were designed to carry.
