SMI Manufacturing

Makers of Intelligent
Towed-Vehicle Braking

SMI's™ Braking Systems make towing a vehicle safer and easier with state-of-the-art braking products. There are many braking systems available today, but as you navigate through our site we are sure you will see the difference SMI makes.

SMI systems have proprietary features that give the user the absolute cutting edge in towed-vehicle braking technology.

Our braking systems are more efficient, easier to install, and cost less than other braking systems. We conduct 100% finished product testing with 300% on critical components. The industry leading 5-year warranty is the true gauge of our quality. Others offer as little as just 1 year!

Number One For A Reason


Air Force One

Air Force One is truly an advance in towed-vehicle braking technology: proportionate, progressive, gentle, user friendly, and fits every towed vehicle with no modifications. Designed for diesel motor homes with air brakes, AFO is the smallest, most effective braking system available.

Stay-IN-Play Duo

Number one choice for rigs with hydraulic brakes. The Stay-IN-Play DUO supplemental-braking system is installed so there is no set up required for towing your vehicle. Simply turn it on... and tow. The DUO energizes the towed vehicles power brakes so it is gentle and consistent.

Delta Force

The Portable-Braking Solution. At 50% the weight and 25% the size of other systems, Delta Force offers proprietary features such as the ball-and-socket actuator, Set-it-Once pedal clamp™, tether hold back, dual-signal proportional braking profile and much more.

Customer Satisfaction

"I want to give a big Thumbs Up! to SMI. I recently purchased (9/16) their Air Force One braking system for my ’03 Holiday Rambler and couldn’t be happier in its performance and their support. Because I was concerned about the system’s installation in my 2017 Ford Fusion, I drove to Newburgh, IN, to have the experts do the work. I was completely satisfied in the service and hospitality while we were there. I decided to add the Wireless dash Coachlink that gives me a positive indicator when I apply the brakes or if a problem occurs. In addition I upgraded my Warranty to SMI’s Total Care Warranty. I already used it when my car was in for maintenance and a worker accidentally broke the breakaway switch. I received my free replacement in two days. Great service!"
