I've taken out my lift blocks out of the rear on my 06 F-150 S/C FX4. It came down almost 2" in the rear. Now I just picked up Groundforce drop shackle kit. They are a 1 1/2" to 2" drop kit. I'm getting ready to install them now. Then next it's time work on the front coming down 1" or 2". This shop told me i could just put in 4X2 OEM coilovers (struts) instead of my 4X4 OEM ones. He says it will drop 1" to 2" just doing that and they shout just fit right in. Anyone know if this is true or not? Thanks for any help in this quest of mine!
