Performance Online, Inc. announces this revolutionary Traction Bar System. Tremendous benefits can be realized when this traction bar system is installed on a leaf spring suspended automobile. These traction bars were developed to achieve specific goals to improve high power traction while staying within hard set NHRA parameters. These items are the newest addition to our POL Pro Series product line. 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 Force Transfer Link into the Front Pivot. The Front Pivot Spring Stop resists this turning motion and also controls the bending of the leaf spring at its thinnest section. 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 further forward). This is where the system emulates a four link system. The pinion angle is also maintained. Available for 62-74 Nova, 67-81 Camaro, 55-57 Belair, 64-73 Mustang and 67-98 Chevy/GMC Trucks.
