Icon shocks

quick question. I’ve been researching suspension for months and one thing that has me from pulling the trigger is this rebuild thing. so everywhere I read, fox, icon, need to be rebuild every 20k-30k miles. I drive about 40k a year obviously I cant be doing that annually. i’m not out running moab or rock crawling in Colorado but I do get on trails monthly where you can definitely break something if you’re not careful.

i still have the factory bilsteins that come on the trd offroad and at 85k miles they still ride great. so this every 20k mile rebuild thing has me confused
