LEVRLING LIFT KIT: DO I NEED ANY SPECIAL TOOLS FOR INSTALLATION? Yes, in order to install this kit on your application, you must use a Torsion Key Unloader/Puller. This is very similar to a gear puller which you can rent at any auto specialist store. We recommend either a 5 or 7 ton puller for this job. This tool is also available for purchase in our other auctions. .
