Question:
What is the difference between item number: AL55FJ and AL86KV for the airlift 7500s thank you
asked by: Matthew M
Expert Reply:
The Air Lift LoadLifter 7500 XL Air Helper Springs item # AL86KV are designed to work with dually F-350's only. They will not fit the Tremor models or single rear wheel trucks.
The Air Lift LoadLifter 7500 XL Air Helper Springs item # AL55FJ are designed for single rear wheel F-350's.
Both of these air bag kits are confirmed to fit the 2021 Ford F-350. These systems have a 7,500 lbs weight capacity and are compatible with in bed hitches.
I have linked a couple of installation videos below.
I also recommend adding the Firestone Air Command II item # F2219 to your truck. This dual path onboard compressor will allow you to adjust the PSI in your air bags individually from the comfort of your cab.
