Vehicle Story

RockJock's 2003 Helldorado TJ started out as a stock 2003 Jeep TJ Rubicon and got the full treatment! RockJock was essentially assembly line building this spec. of TJ at this point in history, so they decided to stick a name on it! That name was the Helldorado package and it basically included every part RockJock made!
