Ken-Tool's dual wheel separator makes removing stuck or frozen dual steel wheels quicker. Can be used on nearly any dual steel wheel truck, bus or van, according to the manufacturer. The separator slips between the frozen wheels and uses the power of a screw-driven pusher to force them apart. Technicians can drive it with an impact wrench. Heat-treated for long-lasting strength and durability. The Made-in-USA Forcing Screw, Pushers and Pullers have large 1-1/8" diameter x 11 threads intended for years of reliable service.
