The ICON Vehicle Dynamics Front Hydraulic Bump Stop Kit for the 2007-2018 Jeep Wranger JK, 2018-UP Jeep Wrangler JL and 2020-Up Jeep Gladiator was deigned to provide unparalleled?off-road?performance?at the limits of wheel travel by adding an extra layer of ICON damping ability to the front of your Jeep.?The function of the bump stop is to control and limit the final position of the suspension during up-travel. The factory bump stops have a limited energy absorption capacity and an uncontrolled release of this energy upon rebound * translating into a harsh ride and poor handling during more aggressive driving in rough terrain. ICON*s Front?Hydraulic?Bump Stop Kit features velocity sensitive technology?meaning?that as the shaft speed increases the damping ramps up to provide excellent bottoming resistance that won*t negatively affect articulation. This energy is then released in a much more controlled manner allowing drivers to focus on the obstacles in front of them rather than being bounced around the cab. 2020-UP JEEP JT / 2018-UP JEEP JL / 2007-2018 JEEP JK FRONT HYDRAULIC BUMP STOP KIT TECH NOTE: Not compatible with Wrangler JL 4xe or Unlimited Rubicon 392 trims.
