SuperSteer Motion Control Unit 1/4″ – Over 30,000 lb. GVW

The SuperSteer Motion Control Unit SSE4055 is a simple, effective and inexpensive way to control body rocking and rolling in air bag equipped vehicles. Easy installation! Comes in a pair.



The SuperSteer motion control unit SSE4055 is a simple, effective and very inexpensive solution to the excessive sway, body roll, bounce and rocking common in air bag-equipped vehicles.

The MCU installs in the air bag supply line(s) and contains a baffle that prevents rapid movement of air into and out of the air bags. The result is significantly improved compression, reduced sway, increased stability and stronger rebound characteristics; which means a smoother ride.

The MCU can be installed on the front and rear air bags, and different baffling ranges are available to achieve the desired ride quality and air suspension sway control.

The Supersteer motion control unit SSE4055 has 1/4” air line OD and is suitable for vehicles with over 30,000 GVW.
