For all 1994 to 2001 Ram 1500 4x4 trucks, and 1994 to 2002 Ram 2500/3500 4x4 trucks, stock height and lifted.  We do not recommend short arms for trucks with more than 5" of lift, however you "can" use them up to 7" if you are willing to have a horrible ride.  You will really benefit from long arms if you are above 5" suspension lift.
