Harness & Restraints

A Harness is one of the most important pieces of Safety Equipment in a race car. Its job is to dissipate energy. In the event of a crash, a harness prevents the mass of the body from moving within the car and transfers the movement of your body to the chassis of the car. Because of the amount of force involved in a racing collision, it is very important to have the right equipment to protect against injury and that it is installed and used correctly. We offer a vast selection of auto racing harnesses from G-Force, OMP, Schroth, Simpson, Sparco, and Takata. If you need help determining your harness needs, give the professionals at DiscoveryParts a call on our tech line at 706-344-1235.
