I have some BC coilovers and was trying to lower them a bit and make sure it was true on all sides. the threaded shock body is siezed into the seat, i can move the lock ring but the seat wont budge.
i used pb blaster and let it soak, nothing
i put it in the freezer and then heated up the seat, nothing
i used automatic trans fluid mixed with acitone and nothing

there isnt much grip to be had on a shock body with no leverage but its moving the whole work bench and still wont budge, any thoughts?

 

Send it back to BC and ask them to fix it. Once you get it loose, be sure to put anti seize compound on the threads that will go down into the body for next time.
