The Daystar D-Ring Isolators install on any standard 3/4" shackle and are constructed of a durable Polyurethane material. They simply snap into place and can be installed or removed in moments. Polyurethane acts as an isolator for the shackle and prevents the shackle from tapping against a bumper or any other recovery point when the vehicle is in motion. The Isolator also protects your bumper's finish from scratches caused by D-Ring contact. Daystar D-Ring Isolators are available in Black or Red and can help add some color to any off-road vehicle. The D-Ring Isolators are sold in pairs and join other innovative off-road products from Daystar, including Winch Isolators, Jack Isolators, Bump Stops, Dash Panels and a complete line of Lift and Leveling Kits.
