rear =

we messured the front stock lug (since i have a messed up front hub in my shed) and it messured 2.75 long the ones listed on the front is a little longer which will give you a better grip with some after market wheels you may have. the rears messured just under 2 inches and being that the ones listed with arp will give you the extra length now much but a better then stock! hope that helps anyone in the future
