Air suspension is designed for comfort, but it has a secret weakness: air moves too fast. When you pull out of a driveway or navigate a sharp curve, the air inside your bags rushes from one side to the other, leading to excessive swaying, body roll, and a "rocking" sensation that can last long after the bump is gone.

What are Motion Control Units (MCUs)?

SuperSteer Motion Control Units are compact, maintenance-free devices that install directly into your air bag supply lines. They contain a specialized internal baffle that regulates the speed at which air moves into and out of the air bags. By slowing down this rapid air transfer, the MCUs act as a "shock absorber" for your air system.

Why Motorhome Owners Love Them

If your coach feels like a boat on high seas, MCUs offer a targeted solution for several common handling issues:

• Reduced Sway: MCUs keep the coach more level during cornering and when exiting steep driveways.
• Eliminate "Porpoising": By controlling the rebound of the air springs, they stop the front-to-back bouncing often felt after hitting bridge abutments.
• Better Braking Stability: They reduce "nose-dive" during sudden stops, keeping your coach stable and controlled.

Simple Selection and Install

SuperSteer MCUs are sized based on your air line diameter (typically 1/4", 3/8", or 1/2") and your vehicle’s GVWR. They are a "fit and forget" upgrade that requires no electronics or adjustments. Once installed, you’ll notice an immediate difference in how planted and secure your motorhome feels on the road.

Note: Always verify your air line size before ordering to ensure a perfect, leak-free fit.
