Machined in the USA IMPORTANT SIZING INFO: We have 3 sizes to fit on the most common jacks. They go by the size of the stud where your handle bolts onto. The most common for 3k jacks and under is 1/2", RAM even goes all the way to a 5k jack with a 1/2" stud. Most 5-7k jacks seem to use 5/8" studs and we've come across some that use 3/4". To ensure you get the right size for your jack we encourage you to measure the stud on your jack. Our adapters are machined to have a little extra tolerance above the listed sizes so they fit nicely.
