If you are committed to driving your Sidekick or Tracker off-road, these are a must have protection item! Constructed for 2" x 2" x 3/16" wall tubing with metal capped ends, these skids provide much needed protection for the very flimsy and exposed stock rocker panel area. Don't tempt fate as we have seen many vehicles with trail damage in the rocker area that could not even get their door open afterwards! These bars are for body lifted models only and welding is required for installation. Fits 2-Door models only.
