Airbag on F150
These Firestone airbags were fairly easy to install and took about 2.5 hours total with no drilling required. I have a 4 inch lift in my truck and due to having suspension blocks in the back did not need the spacer kit to accommodate the lift. The bags are high quality and several of my friends run these on their rigs as well. The ride was immediately smoother.
If you are looking for the best, buy Bilsrein
I have owned my 1993 LS400 for many years. I converted from electronic controlled shocks years ago due to the price of maintenance and repairs on them. I tried several combinations of shocks and springs bur even the top brands left the car feeling mushy. These Bilstein Sport shocks have transformed the cars handling. It feels firm and corners flat without being harsh. They are worth every penny.
