A simple job of installing Corvette polyurethane bushings on your C5 or C6 Corvette can quickly turn into a nightmare when you realize the labor involved to re-use your Corvette’s original shafts and bushing sleeves. The time involved to burn and/or cut off the old bushings, clean the parts and then re-use them can quickly prolong a job that should take 4-5 hours for installation and turn it into 8-10 hours. Zip’s exclusive Corvette shaft & sleeve kit replaces all the aluminum components with new steel components for a quicker polyurethane bushings installation. In doing so, at least 1/3rd of the labor time to install poly bushings in your C5 or C6 Corvette will be saved. The combination of poly bushings & the steel components in this kit is stronger and more responsive than stock, preparing your car for a day at the track, or for a drive down the street.
