Fitment: Upper control-arm compatible with 2002-2009 Chevy Trailblazer, GMC Envoy and Buick Rainier; driver & passenger sides included.
Upper Control Trailing Arm Mount Boxed-Plate Strength: Custom-formed 11-gauge steel panels create a fully-boxed mount that is markedly thicker and stronger than the OEM stampings, ready to accept the arm's full load without flex.
Control Arm Frame-Saver Patch: Oversize side plates weld over rotted frame rails, restoring metal thickness and providing a clean, solid landing for the new mount—no need to section in fresh frame rails first.
Drainage-Correct Design: Laser-cut vent slots and folded drip edges let water, salt and sand escape, eliminating the factory “moisture trap” that caused the original mounts to rust from the inside out.
