Overview
The Bushwacker 40943-02 is a Boss Pocket Style fender flare set for the 2007 to 2010 GMC Sierra 2500 HD and 3500 HD. The set covers the front and rear and adds 2 inches of width and tire coverage. It uses surface-mounted stainless steel bolts and gives the truck a bold, wide look.
The flares are custom-designed for the GMC Sierra to complement oversized tires and high-clearance lift kits. They are made in the USA from thick, warp-resistant Dura-Flex 2000. The OEM-style matte black finish is UV protected and can be painted to match or accent the body color.

Before you buy flares
Fender flares cover the wheel opening and the tire tread that sits outside the factory fender line, so the coverage you need depends on tire size and how far the truck is lifted. Wider or taller tires push the tread past the stock fender edge, which is the main reason a flare is fitted. A flare set like this is usually chosen alongside a lift or larger tires, since the fender has to clear the tire at full suspension travel.
Surface-mounted bolts keep the body panels undrilled, which makes removal simpler later. Before mounting, check the flares for paint or primer on the mounting faces, and recheck fastener tightness after the first few drives on rough roads. Flexible plastic can crack at stress points when the truck flexes hard, so inspect the mounting tabs periodically and keep the wheel wells clear of packed mud.
