Found it thanks. Mine way down underneath the high side..

My 2020 GMC Sierra 2500hd tires rub the sway bar. 37x12.50r20. I just bought the truck and they came on it. What size spacer do I need or do I need to go with a smaller or narrow tire. I like the look of the 37. What is the biggest tire I can put on without a spacer?

I have a 2020 GMC Duramx. I see the high side port, but can't find the low side port. Where is the low side port located?
