As a service center and distributor for jacks, among other items, for over 50 years, I beg to differ on some of the statements I've seen here. First there was Walker Jacks that was bought by Lincoln Automtive. These jacks were private labeled to Snap-On, NAPA, Sears, Ajax and others. Hein-Werner bought Blackhawk in the 80's and Lincoln bought both of them in the early 90's. Many good jacks were dropped by Lincoln and some were painted blue and called Lincoln and some Lincoln were painted red and sold as Blackhawk. Lincoln tried to manufacture overseas to compete with the imports and lost their butts. They sold out to Clore Manufacturing in the late 1990's that stilled tried to do manufacturing overseas and used the Marquette name. The group that had owned Lincoln did not want the new company associated with them and therefore would not allow the use of the Lincoln name. Clore did no better using the Asian manufactures and looked for a buyer. Along came Shinn Fu in the mid-2000's and bought the automotive jack business from Clore. Again, Clore did not want Shinn Fu to use Marquette name, they could not use the Lincoln name but they could use the Blackhawk and Hein-Werner names. Blackhawk had become a line of import jacks and was kept that. So Shinn Fu America used the Hein-Werner name to market the jacks they started making in the USA again. They even brought the jacks being made in Mexico back to within the US borders. I hope I have not bored anyone but thought I would straighten out what was being said. The current US made jacks appear to be ever bit as good as the old Walkers and Lincolns. Oh, the guy that had the 4.5 ton Lincoln, that was a 4-ton. Walker and Lincoln did not make 1/2 sizes like the Import companies except for the older 1.25 and 1.5 short chassis floor jacks. In the long chassis jacks there was a 2, 4 and 10-ton jack. Before Lincoln sold out to Clore they made a 3-ton short chassis jack that was US made, only dies they still had in the US. They still make the 3-ton. Prior to that the largest short chassis jack Lincoln or Walker made was the 2-ton or the special 2.5 ton for Snap-On. Thanks and have a good day.
