I have the spring towers fitted with the Superior Strengthener Kit and also have the towers tied together and bolted thru the floorpan - nothin' is going to move. I have the firestone in-coil airbags fitted and they improve the ride, but was still concerned about the direct stress into the coil tower mount, so have added a set of BOSS 3 rung external airbags. These work between the top of the diff housing and directly into the chassis rail, so no bending moment in play to start bending stuff. I use these in preference to the in-coil units now, however the ride is a bit of a 'wallow' if you put too much air into them to get an extended lift. Just a thought as these take the whole spring mount issue out of play provided the airbags are actually taking the majority of the load. The Superior kit is welded in, and this was the only downside as it was difficult to install on the garage floor situation. I like the idea ofthe bolt in kit especially with comments about them bein g able to pull a slightly bent mount back into position.
