Is this what you bought?
And which one did you get?
I also have the tail wagging the dog problem, it gets very tiring driving down the road all tensed up.
I like to keep it between the lines on the road.
This one don't have a problem passing, or being passed by a truck,
cars seen to actually lift the drivers seat up in the air.
Thanks,
Lee

I bought the adjustable, long before the FSD was available, and adjusted them to the stiffest setting. Made for a much safer and smoother drive. The wheels have to be removed for the rears and I did those first, the fronts were easy but 90% of the improvement were from the rears. My new coach came with Bilsteins and I have replaced only the fronts with FSD so far. I cannot wait to do the rears.

Rookie Rver, I just took a look under 2016 XC chassis and noticed the front 1/2 lines go directly to separate air tanks, I may be wrong but as I understand the MCU's work by slowing the bags from pumping air from one to the other, mine are totally separate in the front. The rears are tied together though and 1/4 lines. I like to make one change at a time so that I know just what is effected with each modification. If I were doing this I would buy the rears first and see what that does. Just me.

I installed these right after I bought my 1999 coach to get rid of it's "drunken sailor sway" while driving around town and on the highway. They made a huge difference even with the original worn out 1999 factory Bill Stein shocks on the chassis!! I replaced those a couple months later with Koni FSD shocks and now it rides level AND smooth!

Is this all there is to them? And where do you buy them?

Lee,
The price for a set of these Super Steer Motion Control Units (MCU's) depends on the airbag airline diameters on your coach. Bigger diameter airlines are priced higher. I bought mine from RVUpgrades.com as they had the lowest price and free shipping when I ordered mine. ( Both front and rear airline OD for my '99 XC coach were 1/2").

As Kwoods pointed out a few posts back, his 2016 XC chassis already had his left and right rear airbags isolated from one another from the factory, but his front left and right air bags were still connected with a 1/4" airline so before ordering anything it will be wise to give Super Steer a call to validate the appropriate MCU's for your coach.

That should be fronts 1/2" to separate tanks, rears 1/4" tied together. Just became motivated to buy rear MCU's, $175 on Amazon direct from Super Steer. I guess I will wait on the Koni's until my next service.

Sorry about the rear / front mix up thanks for the correction
