If you own a classic squarebody, you know that the rocker panels will often become severely rusted over the years. However, more times than not, the best choice is to replace them. BROTHERS Trucks has precisely what you need with our new replacement rocker panels for the 1973-1987 C/K series trucks, including the 1973-1991 Blazer/Jimmy/Suburban. These new rockers have an excellent fit, just like OE, and great corrosion protection due to the EDP coating. These rockers are what your project truck deserves.
