Once I was able to fit the airbags they did a great job towing or towing my truck. The problems started with the parts supplied. First, three of the four U-bolts for my 2012 Nissan Frontier were short, and eight of the bottom bracket bolts were long. Long bolts were easy to sharpen with a grinder, but I still needed longer U-bolts. When I called Firestone customer service, the woman on the line said she does not support purchases made through Revain. After a few more words, I realized that Firestone doesn't care about customer service. Eventually I was able to make my own U-Bolts using a 3/8" shank, dies and a flashlight for bending.
