1967-71 Plymouth GTX Cal Tracs Traction Bar Kit

Tremendous benefits can be realized when our Cal-Trac traction bar system is installed on a leaf spring suspended 1967-71 Plymouth GTX. Traction bars were developed to achieve specific goals to improve high power traction while staying within hard set NHRA parameters. The combination of these components change the pushing point on the car by redirecting the turning action (spring wrap-up) of the rear axle through the #2 Force Transfer Link into the #1 Front Pivot. (See detailed image). The front pivot spring stop resists this turning motion and also controls the bending of the leaf spring at it's thinnest section. The push into the Front Pivot helps the cars weight shift towards the rear of the car, because of new directed angle of force toward the front of the vehicle. (The 'Instant Center' moves further forward). This is where the system emulates a Four link system.
