Ok I understand now I need helper bags. Need to figure put which ones wpuld be best for my application. 2021 F150 4WD tow package Supercab 2.7 stock vehicle including 18in wheels. Allready purchased Belltech 1054sp lowering kit (3.5/5.5 drop). Will be daily driver and will tow 5000lb car/trailer maybe 10x year and then just motorcycles/sea doo/small boat. Not much will go in bed (maybe 500lbs of cargo at times).
Ive seen may helper bag kits from $300-700. What would be best/most reliable for my setup?

 

I've installed many Firestone ride rite and pacbrake airbag kits and the timbren load cushions in all types of trucks. Since your lowering the truck you may have to get something specific like the ridetech or IHC airbag kit there may also be more kits out there. These kits may require modifications because you're using a different lowering kit but you could email them and ask.
