I bet your wear is only on the non cartidge side.
Why? 36s have a fit cart so just as much lubing oil in both legs.
The main problem with fox is their seals are poor…they let dirt in and oil out. Ive not got round to it on mine yet, but looking seriously at some enduro seals. HERE Proper individual oil seals and dust wipers, just the way it should be.
8 strips in 13 months really isnt enough for foxs (depending on how much you ride them and in what conditons). I strip every 3-4 rides in winter/wet crap and 5-6 in dry. Upside down storage is key. You'll be fine with them for years as long as you continue to maintain.
