4" lift some have to and some don't on drive shaft rework for the rear vibration at highway speed.
6" will def require drive shafts .
the drive shaft work some get lucky and play with angles and some have to install a c/v head drive shaft in the rear shaft = $$$
first what size tire you wana run ?
second what is the real endd use of the ride once built ?
lift springs for the front are bolt in job . rear also .
anyone who puts blocks in the front should be shot

. . . . but there is a part called a zero rate / or easy inch and it BOLTS to the spring pack and becomes part of the spring setup . these are different .
don't waste time n reaching . sag right back out . and you can only arch a givin length spring so much before it will NOT hook up to the hangers / shackles as the arch has shrunk the eye to eye spec .
also stock front leafs are TAPPERED leaf and are not ment to be reached at all . or have a generic add-a-leaf put in with them and work correctly.
stock push/pull steering fine with correction parts . but limits flex and gives bump steer on highway more . crossover is best but requires a few extra parts to do it up . 2wd steering box / flat top pass side knuckle machined for steering arm / and crossover steering kit.
