extending arms for srw front hubs

i know it been discused about 40000000 times here. but i cant seem to find the length i need to extend my arms. any info or just a abrupt answere would be awsome. add me on fb to see all the dually projects have going. including the first irs dually. everything built in house including halfshafts and spindles! my name is severed josh.

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
