If you own a classic squarebody, then you know that often times the inner rocker panels will become severely rusted over the years. More times than not the best choice is to replace them. Brothers Trucks has got exactly what you need with their extended inner rocker panels for the 1973-1987 C/K series trucks and SUVs. The inner rockers have an excellent fit just like the OE, as well as better corrosion protection due to the black elecro deposit primer (EDP) coating. They are manufactured with heavy gauge steel for superior strength and have the quality and fit that your project truck deserves.
