Floor jack base plate - the third photo shows different floor jack saddle styles
SD bolt on - Most common newer style, has a lip sticking up around threads of jack with saddle removed
Drop in - Older style floor jack, has 1.16" ˜ 1 3/16" diameter pin
HD bolt on - Most heavy duty floor jacks, has NO lip around threads of jack with saddle removed
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) option 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 Drop in option includes a pin that you press into our floor base plate. The Drop in style is most jacks that were made 10 or so years ago. There are a couple of 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 low lift and tall 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 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. Floor jacks work fine for axles, fuel tanks, doors and bumpers, but transmissions and transfer cases can be difficult or even dangerous 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 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.
