Jeep's JL Wrangler took some big strides in on-road civility and comfort over its JK predecessor but still leaves room for improvement. Loft compliant bushings in the control arms and Panhard/track rods that degrade quickly - even Moreso with off road use and larger wheel/tire packages - contribute significantly to ride quality and the Jeep's composure on road. SuperPro's bushing kit brings a lifetime of maintenance-free durability and superior on-road manners. Drastic reductions in deflection and bushing movement mean a Jeep that tracks straighter, drives more accurately and requires far less constant adjustment and compensation. Whether fitted as a single upgrade or restoration item or as an ideal complement to other suspension upgrades SuperPro helps your Jeep drive as well on the way to and from the trail as it does when the pavement ends. Design features abound to mitigate road and tire noise to keep your Jeep in line with the myriad improvements brought in with the JL generations. These features also permit high levels of articulation so there is ZERO compromise in your Jeep's ultimate capabilities. This kit compliments what the Wrangler does so well - and in ways other SUVs cannot - market-leading offroad capability with enhanced road manners and a lifetime of durable service - all backed by SuperPro's lifetime warranty.
