The 4-Point Jack Adapter offers the versatility to lift just about anything that is large, heavy, and awkward with your jack. Easily converts most jacks to safely hold a solid axle, 3rd member, driveshaft, transfer case, transmission, bumper, fuel tank, etc… Modular design allows easy configuration for different parts. It has threaded supports all around and includes a wrench to make adjustments with weight on it. It has a 3/8″ thick base plate with 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 8″ long 3/4″ dia. all-thread that can be replaced with custom lengths.
We went all the way back to the drawing board for the new 4-point Jack Adapter. Our 1½” adapter pin that replaces the floor jack saddle allowed for the new design that allows you to use 911 Motorsports Floor Jack Extensions. For transmission jacks the base adapter uses two 3/8″ mounting bolts (need to drill your jack plate to mount) and two pins that locate the 4 pt. Jack Adapter to keep it from spinning.

If a jack adapter can be beautiful this one is. Very well made and already put it to work. Used it to support my jeep’s Axle while putting on a lift kit.
