Review on Firestone W237604174 Coil Rite Kit by Marvin Short

I have a 2011 Toyota Rav4 with a V6 engine and a trailer pack. I'm towing a 2200-pound retractable camper, and when the Rav4 is loaded with camping gear and the pop-up is pinned, the Rav4 sags a little, not by much but enough to bother me. I bought these airbags and tried to install them myself but gave up after 30 minutes. Had to take them to my local shop and they did it in about 1.5 hours, they had to remove the wheels and some suspension parts to allow the springs to expand enough to accommodate the airbags. Rav4 showed up this weekend and they worked great. No more sagging. I set them to 25 pounds of compression and they weren't springy at all. When I'm not towing I keep them at 10 pounds and you don't even feel them there. They make a small noise when the springs rub against the airbag rubber, but only when you drive very slowly, with the windows open and on a bumpy road.
