hi guys i just bought my 06 truck and want to do a leveling kit. i noticed that a lot of people just do torsion keys or crank theirs but there is a kit that includes shocks and 3" rear blocks. If you only need to lift the front 2" to level it then what are the 3" blocks for? will that be like a 2/3 lift? i want it to set level. Can someone offer insight?
