It sounds like you bought the 4Runner with the lift already installed and you didn't get the original components, correct? [MENTION=51030]joneseyyy[/MENTION]'s suggestion on the 1st page is good to just put back the OE components with a cheap spacer lift so you don't have to worry about tires rubbing. I chose to keep the OE stuff in the basement in case I ever need the coilovers rebuilt or if I decide to sell the 4Runner so I can put it back to stock (you never get any value back on aftermarket parts on trades).
Anyway, if you don't have the original parts and you anticipate having to do a rebuild, you can pick up some take off parts in the classifieds section or consider keeping the 4Runner on jackstands for the couple of weeks to get them rebuilt.
