yup nitrogen, did you buy them new? i actuallt got a set of comps that where supposed to be hillshooters from this cock sucker on ebay, they messured 15 eye to eye so i had to send them to yanell and they cut them to 14 1/2 and once he opened them up he said they where comps not hillshooters. so i guess i sitting on a set of brand new comps now. so i need to find someone to trade some ew hillshooters with so i have the right shocks
