The 3 point Jack Adapter is our original design that works great on any solid axle, front or rear. It can also work fairly well with bumpers, t-cases and trailer hitches. Modular design allows easy assembly and reconfiguration for different objects to be held. The perforated supports offer quick adjustment and hold the main load. The pinion support is threaded for fine adjustment. Spring snap buttons are used in the telescoping tube to prevent over extension and allow easy disassembly when pressed. Two base plates are offered for floor jacks or transmission jacks. A jam bolt on the base plate locks the main bar in place to prevent shifting while moving. Powder coated and Zinc plated steel. Made in the USA.

You will need to remove the saddle on your floor jack to check which style you have. The styles are listed above. Our floor jack base plate will bolt right onto SD (standard duty) floor jacks, these are generally 2-3 ton jacks, under 2 ton jacks might not work with our Jack Adapter. The HD (heavy duty) style includes an extra machined step bushing that installs over the factory bolt and then works with our floor base plate. The HD style are generally 3-4 ton jacks and include a lot of name brand expensive jacks. The old style Drop in, we include a pin that you will press into our floor base plate. The old style is most jacks made 10 or so years ago. There are a couple other odd style floor jacks, so make sure yours fits into one of our categories.

Floor base bolt pattern - 4" x 6 ½" - The new floor base could also double as a transmission jack base plate as long as your jack works with the bolt pattern. The holes are actually designed to hold a strap to retain whatever you are working on.

Transmission jack base plate - Works with tall and floor style transmission jacks. Comes with multiple bolt patterns for common transmission jacks. If your bolt pattern isn't on the base plate, then drill a new one, there's plenty of room.

Floor jack or Transmission jack?

A floor jack is your standard jack for lifting cars (don't lift yours with the jack adapter) and this adapts your floor jack to also work on lighter, but more awkward objects. A standard floor jack with the 4 point adapter works good, but it's recommended to get some tall jack stands because the jack adapter adds about 6 inches to your jack. It's good to have a second jack handy for changing the height of the vehicle if necessary. Floor jacks work fine for axles, fuel tanks, doors and bumpers; but transmissions and transfer cases can be difficult with a floor jack.

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 high for use under vehicle lifts. The jack adapter works better on a good transmission jack then 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 to 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.
