Ok, our 5th day special is for Vintage Air Products! Sale is good through Dec. 19th.

Purchase any Gen IV Sure Fit Kit and Receive a free upgrade to a Trinary switch. It is normally $39 extra! If you are not running electric fans and don't need the switch, we can work it out!


Purchase any Front Runner system and get a NO COST upgrade from Black to Polished or an additional discount on Black finish!


WHAT IS A TRINARY SWITCH AND DO YOU NEED IT?
The Trinary Switch protects your AC compressor from running when the refrigerant pressure is either too low or too high.

Even better, the Trinary Switch does something else that is very smart - I have never seen this in OEM wiring: The Trinary Switch does not run the cooling fan when the refrigerant pressure is below 220 psi.

Why is that important? Electric cooling fans use power, and your alternator has to produce that power. Fans and alternators have a limited life. When you are cruising at highway speeds, chances are the refrigerant in your system is getting enough cooling and running the fan is not needed. The Trinary Switch is saving your fan and alternator from unnecessary running, which saves wear and tear and a little fuel.

On a really hot day at cruising speed your refrigerant can go past 220 psi and your fan will run, so the Trinary Switch is very smart and automatically handles this.

Both OEM and aftermarket fan controls run the cooling fan(s) when the compressor clutch kicks in, and have no way to read the refrigerant pressure.

AC systems usually employ separate high and low pressure limit switches to save your compressor from destruction. Vintage Air has accomplished this in one switch and added in a 220 psi fan control.

Thank you all for your support, this has been a great year for us at MCB and this is just one of our ways to give back during the holidays!
