RedRock 4x4 is American Trucks’ “house brand,” proudly presenting our line of 2007-2017 exterior components for upgrading your Sierra to better withstand the hazards and challenges of America’s most exciting, interesting trails. These tough and affordable pieces include practical 2007-2013 bumpers made from steel plate and steel tubing, with features like grille guards, bull bars, and D-rings to increase their function for various situations. To ensure these 2014-2017 bumpers remain usable for years, each receives an epoxy pre-treatment followed up with a powder-coat finish, effectively guarding them from rust and corrosion. RedRock also makes dependable 2007-2017 exterior trim pieces, such as wider fender flares and wheel well guards that protect the outer paintwork and inner wheel well from stones and debris tossed up by the tires. RedRock’s parts are designed for bolt-on application whenever possible, and carry a 3 year limited warranty.
