I jack the Shrock Sliders all the time, I rotate my tires, etc...I have YET to see a scratch in the powder coat from the jack..its just not that much of an issue.

Its a little like getting clevis shackles for the bumper. and fussing about how to keep them from rattling or banging as the truck lurches along...etc, and making cut off hose sections to slide over the pins, etc....when the shackles don't rattle or bang the way they are w/o the fuss.

Its a solution w/o a problem.
