There are two model number as one is a supposedly 1.5" drop and one is a 2.0" drop. The links are slightly adjustable so you can pretty well match them up to the drop in the front or you can keep the ass end a bit lower. Not sure why it isn't an even drop all the way around but every car I have ever worked on in the past has this same set up, higher front than rear. Probably due to the weight of the motor?
