D-Rings are great, until they start rattling and knocking against the bumper, causing damage as you drive down the road. Luckily, Daystar has come out with a solution, the Daystar D-Ring/shackle isolator 3/4 inch. The Daystar polyurethane isolator easily snaps into place and keeps the shackle from bouncing around, saving your bumper from knicks and scratches.
