New MRRPM Puller Made in USA from 4140 steel that is  heat treated for a tough finish As with any puller, we suggest applying grease to the threaded section and contact tip of the puller. With stubborn clutches, pumping the cavity with grease first then installing the puller will aid in pulling. Just be sure to clean up after. This is not a tool rental, you use it you own it.
