Superlift's Reflex Track Bars for the Jeep are the only bars on the market to feature dual offset forged ends. The offset forged ends are equipped with the patent-pending Reflex bushings to create the most advanced combination of off-road performance and on-road handling characteristics ever offered. The Reflex bushing is constructed of a dual durometer, synthetic elastomer that delivers superior dampening, ride and handling characteristics. The specifically tuned bushing has a firmer inner bearing material and a softer outer material to dampen noise, vibration, and harshness (NVH). The Reflex bushing is also grease free! The PTFE liner impregnated into the internal bushing serves as a lubricating agent for silent, maintenance-free operation. The Reflex track bars work with Jeep Wrangler JK's equipped with 2 to 4” of lift.
