Anyone try one of these full lock diff kits on a 2018+?

Part number: SPE-67FLDK

It prevents the E-locker from disengaging past the default 15-20kmph.

Says it keeps everything factory and doesn't cause codes.

For $50 I'd be interested in trying it out just for burnouts lol

 

Poorly made and overheated wires are the most common reviews I’ve seen.

 

Thanks for the heads up!

 

Ford uses a PWM signal to control the E-locker. This kit is nothing more than a standard relay with a standard wiring harness and some instructions. There is no way the relay can output a PWM signal. They claim that the relay is internally modified. If that is actually true, the modification likely just involves the addition of a simple diode or resistor.
