The triangulated 4 link design provides a more planted feel and makes room for larger wheels and tires. You can also correct the wheelbase of classic Mopars. The modern design delivers an enhanced driving experience on the street. Plus, it provides the tunability to maximize performance at the autocross, road course and drag strip.
