I was under impression with our 2012 R/T and class IV trailer towing there was a load leveling system . . .

from Dodge:
The Trailer Tow Group IV provides equipment vital for heavy duty towing applications. The package includes:
Class IV receiver hitch
7 and 4 pin wiring harness
Heavy-duty cooling
Rear load leveling suspension
220 amp alternator
Full-size spare tire

I was looking under the Durango today, and did not see anything that looked like compressor lines etc. . . and was concerned that mine did not have this feature. . . I did some searching and it seems that the leveling comes from special shocks that "pump up" while driving to maintain a constant length (ride height). . . Is this true? . Anyone actually experience this effect? (put a heavy load in back, or attach trailer with large tongue weight . . . vehicle starts out setting low in rear, but "pumps up" after the shocks bounce a few times.)?

.

 

Yes it is true. Put it under load, watch is squat, drive in a small circle and look again. Should be leveled out.

^What he said

 

Thanks guys! . . that is so cool, even better than a compressor etc. : )

An interesting note, the shocks have the vehicles VIN # on them, I assume this is for assembly purposes, (to make sure the right shocks get on the right vehicle)

 

Here is more than you probably ever wanted to know about the Nivomat self-leveling shock absorbers:

This is great info. I had asked the same question in another thread not long ago. I'll link it to this thread.

That might be the thread I first saw that explained leveling was built into the shock. . . a link would be good for anyone looking in future.

I was curious if anyone actually experienced it in action.

 

Are they all equipped with those shocks or only the one with the towing package?

Very interesting link . . . THANKS for sharing it!

Did a search on Nivomat, and found another site that expands the description even further.

even more than more than you ever wanted to know.

 

From what I read only comes with tow package.

I'm happy that the system is simple and functional which mean won't break down. But its old tech, I mean look at that 1990 Volvo wagon in the pitcure. lol Since Dodge charges extra for it with the tow package ist disappointing a bit. Could of been standard if you ask me.
