I heard about this conversion for front springs to make it ride better. I have a set of springs, but do not know which they are. According to some forums I have read, there are 2 types of front springs, a "X" code and a "V" code. I don't have the code from the truck, but the part number on the end of the spring is 2C34 ADB R 100 3. If anyone can check their truck or knows which this is, please tell me.
