These traction bars were developed to achieve specific goals to improve high power traction while staying within the hard det NHRA parameter.

The push into the front pivot helps the cars weight shift towards the rear of the car because of the new directed angle of force toward the front of the vehicle (the "instant center" moves farther forward). This is where the system emulates a four link system.
