I'd like to mount a high-lift jack. What do you suggest?

To mount a high-lift jack, a set of our Riser Mounts with the Quick Fist Original Clamps will do the trick. But, we actually prefer another mount we currently do not sell. High-Lift makes a fully rigid mount called the 4XRAC that will bolt right up to our 2" on center slot spacing and is very easy to use.
