      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.

      By utilizing the latest in Scanner Solutions and CAD Software Rust Busters crack engineering team is able to capture your specific model truck's frame contours down to the smallest detail. We take a Modern Approach and tailors each frame section to fit your vehicle and application with the unique vision that puts Fitment, Installation Ease and OE compatibility to the top of our priority list. We strive to set ourselves apart from the competition by being better in every area the current market has to offer, with a combined 45 of experience under Rust Busters Engineering staff we are here to put an end to all your rust issues. Because of this, we back all of our frame pieces with a Lifetime Warranty.

      Nice product

      Just a little grinding to get the rear bumper mount on, seems like it adds a lot of strength to the frame.

      This an excellent product, it’s heavy duty and fits perfectly! It does take some skill and a bunch of good cutting wheels for your grinder and of course a decent size mig welder. Just follow there directions and use some common sense and you’ll be fine.
