Do I Need Spacers to Install Air Bags on a 2021 Ford F-150 Tremor?

Question:

I have 21 F-150 Tremor looking to get these ultimate 5000s with the cradles, do I need any spacers at all?

Hey Dan! It looks like the lift in the back of the 2021 Ford F-150 Tremor only has a 2" lifting block. You will not need any spacers to install the Air Lift LoadLifter 5000 Ultimate Air Helper Springs item # AL54JQ.

@Dan That changes my answer! You will want the Air Lift Universal Air Spring Spacers for LoadLifter 5000 and 7500XL item # AL52420.

Hey sorry all the questions just to be sure so since I have a 1/2" taller rear blocks I will need those 2" spacers? I just ro have everything before I install so I'm not waiting for stuff appreciate your time. Thanks Dan

@Dan Yes, you do! You can get away with a 1"- 2" but any larger and you would be limiting the range of movement in your suspension.
