Hell wig sells two different rear sway bar kits. One is a 7/8 inch bar with bushings and the other which is of my interest is a kit p/n 7883 for ram 1500 with 2-4 inches of lift. My question is some sources say the bar is 7/8 inches and others say 1 and 1/4 inch. Think I may have seen one say 1 and 1/2 inch diameter. Anyone know the real truth?
