Hooker is a brand started by Gary Hooker back in 1962. It all began when he designed his own header for his 409 Chevrolet and became popular with other local racers. His business grew and became successful. Soon enough, Gary managed to hire employees and manufacture his headers in their South Ontario, CA building.

This company created performance headers for drivers on the race track. Famous racers trusted Hooker because of their dedication to what they do. But as time went by, Hooker expanded their reach by providing parts for skateboards, bicycles, motorcycles, and wheels.

Hooker is a true leader in their industry. They are devoted to delivering an excellent driving experience to every driver whether you're driving a car or a truck. Push your limits and reach your best performance with Hooker products!
