These machined QuickCar torque absorbers are IMCA-legal. They're made from solid steel and yet are lighter and provide up to 4 in. more travel than spring torque absorbers. These torque absorbers are designed with a threaded cap for ease of changing the different bushings offered and are built with brass bushings to help eliminate binding. These new torque absorbers are track-proven to increase more forward bite off of the corner without a loss of traction down the straights.
