IIRC i think its 1.5 " but dont qoute me, can some one conferm this

3/4 hubs suck the wheel in around 3.5 inches. you extend 2 inches out on your lowers.

so please correct me if i am wrong,

do you only leagthen the lower and not the upper arm ?

if so why and how do you go about correcting camber when aired up

no you have to shorten both....on my 85 model i kept the stock hubs and shortened mine 1 inch....for some reason that i have yet to figure out my driver side wheel clears the fender awesomely...my passenger side however does not...it barely clears....has anybody else with shortened arms noticed this also....but what i plan to do is swap to a SRW hub and make my arms 1.5 inches longer than stock(2.5 longer than they are now) in hopes of the passenger side clearing better and recovering some lift that i lost...my upper arm bottoms out on the spring pocket at 120psi and its driveable but only about 6 inches off the ground
