As the quality of these airbags you can tell as soon as you open the box, they are well made, the instructions are simple and very well explained, I fitted mine on a 2012 Dodge Ram DRW. 1 ton dually to carry a 14,000lb fifth wheel which I haven't had a chance to test yet. The only problem I had was installing them, no one said a word about all the pipes, wiring, brake lines, exhaust guards etc making installation difficult. I have to say I didn't remove the wheels, that might help. In total it took me about three hours to install it on my truck. These guys say they installed it in an hour and a half. Spring . I think they either had a 3/4 ton or 1/2 ton TPO truck that didn't have everything they needed or they sat in a waiting room in the garage for an hour or an hour and a half. I took an empty test ride just to make sure they didn't rattle or wobble, which they really didn't. I just hope they work as they say when I'm towing this heavy RV and they should, from what I've read on the forums. and reviews.
