I have the Firestone, and am generally pleased with them. I installed them myself, but had a rough go of it. Wrong set, and incomplete parts (I was missing every nut for the package!). But after I got them installed, they did just what they're supposed to do. I got them to help level the rig some, but also to help with the ride of the 5th wheel. They did make a considerable difference, but did not help the chucking completely. I think after I do some mods to the kingpin of the 5er, it should settle the whole thing down nicely. Oh...if you don't deflate the bags after at rip, man, it will rock your teeth! Trust me on this!

I thought I was wrong once, but I was wrong!
