The floor jack extension 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. The extension tubes are swaged from 1.5 x .120 DOM tube and have a pressed in stop collar.
All styles come with:
-1 1/2" diameter conversion pin - 1018 steel
-6" and 11" DOM extension tubes
-4x4 saddle - laser cut, formed & welded - 1/4" A572
Jack Saddle Styles - shown in 2nd & 4th picture
Bolt on - Most common, has bolt that uses 10mm hex.
Cross Pin - Fits 1½ ton jacks that use a cross pin to retain the saddle.Drop in pin - Fits older style jacks, also in 4th picture.
For up to 3 ton floor jacks - The longer extensions add leverage to your jack base, which will bend or break if used improperly. The fail point in our destructive testing is the floor jack base, where our 1 1/2" pin attaches. This bends your jack, then our extension pin and tube with around 500-1000 lbs of side load, depending on the jack and extension. Weld our 1 1/2" pin to your jack for increased strength, a couple stitch welds is all it takes.
