Said it would fit my 2022 Chevy 3500 but it has the wrong connector and won’t fit so I don’t know about performance. Looks like a good product though

Heater cord was a very loose fit to heating element. Had to re-do install and zip tie it in place due to loose fit, after only a few miles of driving.

My factory cord had just deteriorated over the years. As mentioned by some other buyers, this does not come with any heat shield. I was able to purchase some aluminized heat sheathing for wiring that worked great for me. Now I can heat-up my truck again during the winter to have it at it's optimum temp when I am ready to take off.

Needed a replacement heater cord for my LB7. This worked well, except it does not include the heat shield sleeve the factory one had, so you will need to supply this on your own. Would be nice if that was included since a broken factory cord doesn't likely have reusable heat shield sleeves.
