Review on Daystar Black D-Ring Shackle Isolator Pair | Protect Bumpers, Reduce Rattling | KU70056BK | Made in America by Jake Powell

I've been using them on my FJ40 bumper shackles for about 5 years and they protect my bumper shackles perfectly and stick well to the elements. You obviously have to take it off to use the brace, but that doesn't matter; they appear immediately. I only had to buy another pair because I lost one on the trail after taking it off to use the shackle to rebuild the winch.
