    Yes, for the SuperSteer MCU, a pair is installed at the front and a pair at the rear. Selection is based off of the air bag suspension feed line diameter and gross vehicle weight of the motorhome. This unit is for an air line with an outer diameter of 1/4" and gross vehicle weight over 30,000 lbs. Sizes available include air line OD 3/8", 1/2", and 3/4" for GVW under and over 30,000 lbs.
