I just traded my 2020 Trail Boss for another truck, and I purchased the fluids anticipating changing the fluids had I kept the truck. Now I no longer need the items and it’s been 40 days so I can’t return. See pics. $85.00 plus shipping. Check your VIN to make sure this will work. Chevy has 2 different axles. PM if interested. I only have a PayPal account.
