Question:

2021 GMC Sierra 1500 4 x 4. Looking to purchase and install your AL88288 air lift suspension kit. My question is will it work with the 2 lift kit I already installed? Thanks

Hello Jason, thanks for reaching out. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88288 are correct for your 2021 GMC Sierra 1500 4x4. They can work with the 2" lift; all you will need is the 2" spacers part # AL52420.

Please note if you have a 5th wheel or gooseneck hitch in your bed, the air bag kit will be compatible, but some drilling will be required.

Do you have a hitch in the bed? What kind of trailer are you pulling? Replying on this page is the fastest way to get ahold of me.

Hey Jason, did you have a chance to install the air lift suspension kit with the spacers for your Sierra? I'm curious to know if it worked well with your lift kit, as it could help others with similar setups.
