I would assume so. I do not have the TB, just an LT Z71. Can you provide me the exact part numbers you used? I am having trouble locating them, maybe I am looking for the wrong part number.
Seeing your reaction made me call to try to find the 5100s for my 2020 Silverado 1500 with the Duramax. When/if I can find them I am going adjustable in the front to level it out.
