This kit is specifically designed to safely unload your torsion keys when installing new WULF Torsion keys on your vehicle. We stress test and retest and then real world test it a dozen more times on 1 ton pickups to make sure that it can hold up to any of the torsion bars we sell keys for. This is a shop quality tool and can be reused multiple times without any issues. Most tools on the market are a one time use product due to the poor materials and design. The amount of pressure that your torsion bar exerts requires a tool that can stand up to the job, don't trust your fingers or limbs to random brands who don't have a single picture or proof of their tool in use.
