i believe the back spacing is 5.5 but im not exactly sure, i picked them up used but i never had the chance to use them and a buddy of mine was selling a full set front and rear for dirt cheap and he wouldnt split up. they are just the wheels no lugs or centercaps and they have some pretty spent bfg drs on them. looking for 200 + shipping and paypal fees3%. can get pics if you need. will consider trades as well im really looking for drag suspension stuff for front or sra rear.
