How to Determine Correct Spacers for Air Lift LoadLifter 5000 Air Helper Springs in 2016 GMC Sierra

Question:

I have a 2016 GMC Sierra with a 4.5” zone lift. I have the air lift 5000 bags and need a spacer. What size spacer do you recommend? The old block insert the leave springs was about and inch and a half and the new one is about 3.5.

To determine the correct spacers in for your GMC Sierra with a 4-1/2" lift and Air Lift 5000 Air Helper Springs such as # AL57338 you wll need to do a bit of measuring.

There is a diagram I added from Air Lift what you will need to measure to ensure the correct spacer kit. You will need to measure the total distance between the mounting surfaces, and subtract that by 5-1/2", which is "A", the air spring design height for these air bags. That will give you the correct lift spacer, which is most likely going to be the Air Lift Lock-N-Lift Spacers for Lifted Vehicles - 4" Lift # AL52440.

I have added a link to our selection of lift spacers for you to check out.
