 A common failure on 4th Generation 4Runners & FJ Cruisers is rust penetrating from inside the frame.  So of course anything connected to the inside of the frame is at risk, now couple that with a tire that's slinging road salt, dirt, debris, snow and rain in that same area, you have a real recipe for disaster.  Plus, since the springs and shock control the ride of your FJ Cruiser & 4Runner, it poses a safety risk as well.  Of course, when situations like this arise, you can count on Rust Buster to have your back.  We designed this to match the Factory Shock and Spring mount perfectly.  So get that Welder out and get your FJ Cruiser & 4Runner handling like new again.
