Used one season. No drilling involved. Just slip them on. Take them off for shows or whatever. Go on in seconds. Never had a problem with them coming off. Paid $150 new. Will sell for $100. FREE CONUS SHIPPING
I did it last weekend on jack stands. 4 point. Was no big deal other then popping out the metal plugs left from where ford punched the holes in the frame. Had to take a file to the spacer to shorten them a bit. Car is much stiffer up front in corners. Very happy. Easy install.
Just looked on my dealers web page. The car I originally ordered on Dec 7, 2017, and was promised in 4-6 weeks is being delivered to them on 8/08/18. Insane. Glad I didnāt wait.
