This tool is an absolute lifesaver. Or timesaver. Both. The lock ring on my Magnum was like welded to the car. No matter how hard I beat on it with a hammer and chisel it wouldn't budge. This thing plus a pull handle had it off with just a tug. I've seen other people fabricate their own tool for this, but most of us don't have welding gear or knowledge. This thing is solid as a rock too. No bending or deforming, it just gets the job done. Great product, great price, fast shipping with Prime.
