In some cases the Toyota 4Funner requires two or even three 9/16” washers for the skid plate crossmember. In those cases, the factory bolts are not be long enough to allow proper engagement for the skid plate to the frame. For situations like this, Icon recommends using the old bolts that came out of the swaybar mounts. The ICON swaybar relocation kit provides new hardware so the old hardware they used to be in the OEM Location is available. The bolts are longer, the correct diameter, and the correct thread pitch to be a good substitute for a longer bolt that will be needed for a three washer install application.
