2/24/23 update - Coarse Thread Bolt On adapter pins are now available! A new style of jack saddle mount is becoming more common, so we have made it more universal... Our 1 ½" adapter pin is now available to fit M24x3.0 coarse thread pitch jacks. These are mostly found with Duralast and Torin brand jacks... Let us know if you find other applications.

The floor jack extension converts your floor jack into a universal 1 1/2" pin. The saddle alone gives a 2 to 3" extension, it comes with 6" and 11" extensions that you can stack for a total of 16" extension. 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.

Recommended limits – full jack rating w/ 6” ext. –75% of jack rating w/ 11” ext. – 50% of jack rating w/both stacked at 16” ext.

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 -
Bolt on - Fine Thread       -Most common. Includes large washer for jacks with a lip sticking up when factory saddle is removed.
Bolt on - Coarse Thread   -Used on Duralast, Torin and potentially other brand jacks
Cross Pin                          -Fits most 1½ ton jacks that use a cross pin to retain the saddle.
Drop in pin                       -Fits older style jacks with 1.17" or 1 3/16" pin

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.

Jack extension
I was looking for a jack with an extension. I’m so happy I came across this product. It fit my old drop in pin style jack and the machining on the pin to the cradle and extensions have zero slop. I definitely recommend this to anyone who is looking to upgrade their jack, or an awesome addition to a new jack.

Better than blocks
I just ordered a second set of these for another Harbor Freight jack. The HF 1.5 ton jacks are great but don't have the max height needed to change tires on the off-road vehicles without blocks. These replace the blocks way better. Thanks to Casey LaSalle for the heads up on this product.

Must have for Harbor freight jacks
Best addition ever for the cheap. HF jacks. Makes them just like those over priced name brand ones.

Amazing, modular idea and implemention
This is way safer and sturdy than using blocks! I purchased the adapter saddle to retain use of the factory lift pad, the big flat plate, and under the accessories section on the website added the $6 Trail Jack Weld Tube so I can use all of these pieces with my bottle jack! I can just toss any extensions/adaptors I think I might need in my recovery gear when I head out on the trail. This is a must have for anyone that uses their floor jack more than infrequently! My 6ton Pittsburg jack did require me to trim the threads on the pin a bit shorter, but everything fit perfect and will make using the jack in the garage easier, faster and safer!
