Expert Reply:
The Timbren Springs # T28MR has an overall height of 5-11/16". With your 2021 GMC AT4 having the factory lift you will want to measure the distance from inside the cup on your current jounce bumper to the pad on the axle. We do have a 1" Spacer # A25723-90AH00 and 1/2" Spacer # TA25722-90P00 which can be added to the jounce spring to give you the recommended 1" of air gap between the jounce spring and axle pad. You will likely need to source a longer M10 - 1.50 bolt locally to account for the added height of the spacers.
