It does NOT matter which end of the spring....most put it on top.....4 wd has the nuts on it, the 2WD only sits there,.. the reason that your spacer or puck did not raise it like you wanted it too, is most of the sellers have NO clue how to tell how much it will raise it, the weight of an engine from v6 to v8 makes some difference ,but mostly its the manufacturer,( POINT ). a friend bought some they told him they were 2 inch they turned out to be 4 inch and the ride was TERRIBLE.... Sit the spacer on a table ....get a tape measure and measure on the outside from the bottom of the spacer to the top, write that down, then put the tape measure inside where the flat part is this is where the coil spring sits, then measure to the top of the spacer, write that down, subtract one from the other, what ever number you have left.double that , that is just about what you will get in lift..........it works pretty well, i have installed lots of spacers in 2WD's.........2 inch outside measure... subtract....one inch inside measure = one inch left, double that means that if you had those measurements on a spacer it would raise it right about 2 inches in the front. just to let you know, i bought 4 - 2 inch lift spacers from different companies all were different..............I make them measure them....before they send them...
