Im looking to put wheel spacers on what is the length of stock studs? I dont want to cut them so would a 1.5'' or would a 2" be best?

 

im having a MAJOR problem with this myself.... i have a 02 5.4 ext cab with a 3" lift on 18" xd diesel rims wrapped in 33" nitto trailgrapplers and i wanted to do some spacing.... now i recently replaced my rotors and everything. i got everything from napa just stock replacement parts. my studs at 1.75"s long. when i put my lift on, i also had bought 1.5" spacers and of course, my rotor studs stuck out past the face of the spacer so therefor, they did not work and i sent them back. i was trying to find some .75" spacers or something... idk. anyways hope my f**k up helps you and saves u time and money lol.
