The Griot's Garage BOSS™ 2" Orbital Conversion Kit allows your 3" Random Orbital to take advantage of our family of 2-inch pads. Smaller 2" pads provide better access to thin A-pillars, grilles, intricate body panels, produce more pad rotation so they remove defects faster, and won't bog down under load. Backing plate fits via 5/16"-24 threaded shaft. The kit includes a 2-inch backing plate and one of each of the following BOSS™ pads: Microfiber Fast Cutting, Microfiber, Fast Correcting Foam, Correcting Foam, Perfecting Foam, and Finishing Foam. Compatible with the Griot's Garage 3" Random Orbital (10739) The G8 (10908).
