The 4-Point Jack Adapter offers the versatility to hold just about anything that is large, heavy, and awkward with your transmission or floor jack. Modular design allows easy assembly and reconfiguration for different objects. Easily converts most jacks to safely hold front and rear solid axles, fuel tanks, transfer cases, manual transmissions, bumpers, etc.

We went all the way back to the drawing board for the new 4-point Jack Adapter. Our 1½" adapter pin allowed for the new design that's better suited for floor jacks, with threaded supports all around and includes a wrench to make adjustments with weight on it.  For transmission jacks the base adapter uses a single center bolt(need to drill your jack) and two pins that locate the Jack Adapter. Made from 3/8" plate that's threaded for 1/2" bolts which hold the U-slot bars. This design makes it easy to center the jack under the load, then move the supports to find pick points. Threaded supports are 3/4" all-thread that can be replaced with custom lengths, 8" included.

- Top/main bars are 1/4"x 1¼", adjust from 7-28” wide and provide solid load points.
- Bottom bars are 3/16"x 1", adjust from 6-25” wide, they pivot around one bolt and stabilize the load.
- 800 lbs. capacity at maximum extension, using just the top main bars.
-Comes with wrench for adjusting threaded supports and tightening bars.
- Made in Oregon, USA

Transmission jack base plate - Works with low lift and tall style transmission jacks.

Floor jack or Transmission jack?
If you're working on the ground a floor jack works fine, but it's more important for the weight to be centered.

A floor jack is your standard jack for lifting cars (don't lift your car with the jack adapter) and the jack adapter allows you to utilize your jack for working on lighter, but more awkward objects.  The jack adapter adds about 6 inches of height to your jack so tall jack stands can be useful. It's also good to have a second jack handy for changing the height of the vehicle if necessary.

A transmission jack has a head unit that gives two more axis of rotation and a large base plate with arms (for transmissions), these jacks can be low on the floor or tall for use under vehicle lifts. The jack adapter works better on a good transmission jack than a standard floor jack. Having the ability to adjust the awkward thing you are moving is very helpful. Cheap tranny jacks have a lot of slop that needs to be taken up and can still be a little excessive. Once you get familiar using the jack adapter and finding the balance point, it's no big deal. If you are only using the jack adapter for solid axles the 3 point is just fine, but the 4 point is better at that and everything else.
