4x4 - Floor Jack Extension - Bolt on - Fine Thead

**Verify your jack is correct before ordering** Check pictures to find your jack saddle style. Bolt on - Fine thread is most common, 24mm-1.5 thread. Bolt on - Coarse Thread is found on Torin & Duralast jacks. Cross pin style is used on most 1.5 ton jacks. Drop in style was used on older jacks made more than 10 years ago.
Converts your floor jack into a universal 1 1/2" pin. The saddle alone gives a 2" extension, it comes with 6" and 11" extensions that you can stack to get a total of 16" above your floor jack. There are multiple pin styles to work with different floor jacks. We came up with a 4x4 saddle with one side for round tubes and another for standard frames.
Made in USA - Extension tubes are swaged from 1 1/2" DOM tube. Saddle is 1/4" A572 steel and everything has a nice Zinc plated finish.
Recommended limits – 3 ton or full jack rating w/ 6” extension –75% of jack rating w/ 11” extension– 50% of jack rating w/both stacked at 16” ext.
