I am looking to recharge my nitrogen in my shock and am unsure of places around me that will do it. I took a gauge to it and got a whopping 40lbs. I believe it's supposed to be around 130-140. I assume because it is a 1998 it would have leaked out eventually. Anyone know of a local area in Mid Massachusetts, North CT, or North RI? Thanks for any replies. If you know of a place and have had it done could you be so kind to leave what they charged you? I have read between $10-25 which is nothing major to me, so I wouldn't have any problems with the price, seeing as it isn't something that has to be done monthly.
