Hedman Husler headers are made in the USA, and designed by racers, for racers. This new catalog contains more than 1600 part numbers designed specifically for racing and high performance street use. Even if your car or truck never sees the race track, if your vehicle's engine has aftermarket cylinder heads, chances are you'll need a set of Hedman Huslers. In business since 1954, Husler's Alpharetta, Georgia plant manufactures street & strip, dragster, funny car and pro-mod drag racing headers, as well as, asphalt and dirt track roundy round headers. Over the last couple of years, Hedman Husler has also been producing top of the line headers and conversion kits for installing GM LS Series engines into dozens of classic GM muscle cars and trucks.
