Difference Between Air Lift 57552 and 57550 LoadLifter 7500 XL Air Helper Spring Kits

Question:

What is the difference between the AL55FJ and the AL86KV kit? I would be installing on a 2020 F350 short bed, single wheel FX4, 4x4. thanks

The application for each air helper spring kit is the difference.

The difference between the two is that the Air Lift 57552 which we carry as part # AL55FJ is for single rear wheel models while the 57550 which we offer as # AL86KV is for dual rear wheel model 2020 F-350 trucks. For your SRW model, you'd want to use # AL55FJ.

You might also be interested in an on-board compressor kit, part # AL25856 that would allow you to adjust the pressure in the system from the truck cab with the push of a button. This isn't necessity, but if the loads you carry in the truck vary, being able to have that ability to fine tune the support offered by the air helper springs is a very convenient feature.

I've linked to some product videos that you might find helpful.
