Helpful Expert Reply:

For your 4,000 pound Equal-I-zer weight distribution system I recommend shank # EQ90-02-4340. It has the proper hole diameter to mount the head to the shank (5/8 inch). You can also use # EQ90-02-4240 or # EQ90-02-4140.

The Equal-i-zer Weight Distribution Shank # EQ90-02-4400 has the mounting holes with a 3/4 inch diameter. The head on your 4K Equal-I-zer system should be using 5/8 inch diameter bolts so it would not work with this shank.
