We usually eschew factory accessories, but in the H3's case, the parts are some of the best available and really work well. Jerry Seiner Hummer had the H3 grille guard, rock guards, and rubber mats in stock. The grille guard protects the front of the H3 from branches and other things that could break headlights or do worse damage. The rock guards fit tight against the body and are strong enough to take hits and not bend. The floor mats catch slush, water, and mud, protecting the interior. We're impressed with these accessories and Jerry Seiner Hummer's service.
