Product Details

Hedman Hedders are designed to fit the applications listed, and come packaged with the required gaskets, bolts, nuts, connectors and emissions components (where applicable). We offer one of the largest selections of 50 state legal hedders, as well as, many more for off-road and racing use.

Standard-duty, Hedman Hedders are manufactured using 18 gauge, mandrel bent primary tubes (some models built using thicker 16 or 14 gauge tubing), and 1/4 flanges (some models use 3/8" flanges).

Some hedder applications may require the use of special engine mounts, mini-starters, etc. Additionally, some stock or aftermarket components may interfere with the proper installation of these hedders on your vehicle. To ensure that you are choosing the best hedder model for your specific situation.

A NOTE ABOUT UNCOATED HEDMANS:
Hedman offers these uncoated hedder for vehicle owners who wish to apply their own type or color of coating. The Black paint applied to them at the factory is merely to protect the bare metal from corrosion while in inventory and during shipping. This coating is not a high temperature paint and will burn off after only a few minutes of use on a warmed engine. Although an uncoated hedder can be used, we recommend the use of a thermal coating, or high temp paint to protect them from the elements, and prolong their life. ALL uncoated Hedman Hedders are available with HTC Ceramic-Metallic thermal protection, and is factory backed for 5 full years.

Contrary to popular belief, the use of a thermal wrap on hedders will cause crystallization of the steel tubes and actually dramatically shorten the life of the hedder. The use of hedder wrap is so detrimental to the integrity of the hedder, its use will void your hedders lifetime warranty.
