The Bolt Puller from Mo Clamp is designed to allow the technician to get a straight, even pull on the center of a bolt. Originally intended for lower suspension areas as a way to pull floor pans down after being pulled up in a suspension hit, the Bolt Puller is also great on helping straighten frame horn ends on light trucks and vans. Made from Mo-Clamp Tru-Tuff steel alloy and rated at 2.5 tons pulling capacity, door pillar bolts will yield quickly to the strength of this tool.
