Product Description If you feel hesitation when taking corners in your Slingshot, then it is time to upgrade from the flexible stock sway bar to the Twist Dynamics Sway Bar. Stock Sway Bars have extremely low Torsional stiffness (350 lbs/in.) which can hinder your driving experience and impact your ability to take corners at higher speeds. While Competitor Type Extra Thick sway bars offer an improvement from stock due to an increase in Torsional stiffness (+/- 570 lbs/in.); Twist Dynamics Sway Bars offer much more improvement due to a solid bar construction with the highest Torsional stiffness (+/- 650 lbs/in.) on the market. Available in all Polaris Slingshot colors for an upgrade (Black is standard).
