Firestone Airbag Lift Spacers

Firestone Airbag lift Spacers Project

After installing heavier springs on the rear axle, the Firestone Air Bags no longer sat on the spring, but had about an inch and a quarter space between them. I fabricated 2 inch square tubing with 1/4" thick walls. I also had to make bottom plates to make the bolted connection to the spring pack. I needed 7" bolts but the hardware store only had grade 5 bolts in stock so I went with those. The air bags now make proper contact with the springs and lift and level the TC better. I also like that the air bags provide a third center support on the frame along with the front and rear shackle. I also installed new U-Joints. Next up will be shock absorbers.

  • did you still need the airbags at that point?  to me the best suspension is one you build good enough you don't need air bags, and yes I did use them on my 98 f150 with my old pull behind trailer.  changed to timberins threw the airbags in a corner of the garage and never looked back.  I should dig them out and put them on the buy and sell one of these days.
