SuperSteer Motion Control Units
If you own a motorhome with air spring suspension, you've probably noticed a rocking and rolling sensation when driving into/out of driveways. The SuperSteer Motion Control Unit (MCU) is a simple, effective solution to this problem. The MCU installs in the air spring supply line(s), and contains a baffle that prevents rapid movement of air into and out of the bags. The MCU can be installed on the front and rear, and different baffling ranges are available to achieve the desired ride quality. For plastic airlines only!

- Affordable, reliable, and easy to install!
- For Plastic Airlines Only!

Measure the outer diameter of your airlines for correct fit!
Front and Rear Air Lines might be different!

SuperSteer's MCUs have different weight ratings!
Please make sure you have noted the GVWR of your coach. We offer 2 weight ratings for each of our MCU airline sizes- under 30,000 lbs and over 30,000 lbs. This will effect the ride quality. For plastic airlines only!
We make our MCUs in many sizes to fit most airlines!
- 1/4"

SuperSteer SSE5065 3/8" Motion Control Unit for coaches over 30,000 lbs GVWR
Not sure of GVWR? Here's where to find it!
You can find the GVWR of your coach on the information plate, usually located by the driver's side wall or near the main door. Please note: Do not use GCWR, as this is a combined weight rating that includes towing capacity.

We have an Tiffin super C . It really rolled when turning or going up driveways. I got these you just cut out a small piece it the airline that goes to the airbags and push them on. Haven’t driven a lot since putting them on but really noticed the difference

I installed on my 55,000 pound 45’ Country Coach to hopefully reduce bony roll around turns, both sweeping and tight. I must admit, I was a bit skeptical that these valves could make a change, but wow, was I in for a surprise !!They made the coach handle so much better it really is unbelievable!! I highly recommend them, if you have a tag axle you only need to install them on the front airbags.My coach has two airlines per bag so I needed four total.
