a little sag problem???

installed tnt kit. arms are extended and not really getting 7" of lift more like 4".. before i put the long arm kit on i tool everything off and installed my new 7" springs. had it sitting on just the springs for maybe a week. finally installed the new TNT long arm kit and its not sitting much higher? i didnt think that weight would sag the 7" springs down that much so fast... is that possible or do i most likely have something else wrong?

What kind of springs? What were your old springs?

What measurements are you using to determine how much lift you're getting?

Thats weird usually as guys we measure things as being bigger not smaller.:gee:

well they are RE7.5" springs actually. the old springs are rough country 4.5". and for the arm measurements, im trying to go by the instructions.."mess with the arms until you get the correct lift you want". so where do i go from there.. like i said its the tnt y-link
