They look great on an rti ramp and look pretty impressive flexing but its unstable as all hell.
Agreed, I ran them for about a month and they suck on the trail. They would work well if you used them in conjunction with a trac-bar, but other than that they are crap.
Just put the chevy's in the rear moving your front hanger 11" forward eye to eye and your shackle hanger back 4-5 inches, put the rears up front, buy/build a 1" drop hanger and use a 5.5" eye to eye shackle for the front springs.
