At the 2 different Dealers I shopped I could not find a 2020 Trail Boss with 20" tires/wheels that had the features I wanted. They all had 18: tires/wheels.
So I bought a 1500 with the Z71 package in a LTZ and told them to add the Trail boss 2" lift kit.
I am getting added this week about $1725 Parts and labor.
The list of parts you mentioned is what they said they would be replacing.
Thank you New Dude for your comments
