Thanks redneck6....the upper and lower arms are made out of 1 1/4" .125" wall DOM and there is just a slight bend in the rear tube on the lower control arms to allow clearance for the air bags....and the lower balljoint plate is bent roughly 10* up to keep the balljoint from binding when aired fully up....and the rear trailing arms are made out of 2"x3" .125" wall rectangular tubing with a 2 1/2" drop built into them
