Towing RV Trailer Vacuum Braking SMI Smartbox G-force Controller II ^Sale

An "SMI Smartbox G-force Controller II" is a device used when towing an RV trailer, which utilizes a G-force sensor to automatically apply the trailer brakes proportionally to the braking force applied to the towing vehicle, essentially providing vacuum-assisted braking on the trailer through a pneumatic system, ensuring smoother and safer towing, especially during sudden stops. 

 

It senses the G-forces acting on the towing vehicle during braking and uses this information to activate the trailer brakes at the appropriate level, providing better control and stability. 

 

This system uses a vacuum pump to apply the trailer brakes, ensuring consistent and reliable braking power. 

 

The key component is a G-force sensor that detects the deceleration of the towing vehicle, triggering the brake application on the trailer. 

Improved towing safety by preventing trailer sway and jackknifing 

 

Smoother braking experience for both the towing vehicle and trailer 

 

Reduced wear and tear on trailer brakes due to proportional braking
