HITCH BALL HEIGHT
Measure from the top of the ball to the flat part of the base where the ball will sit on the hitch head. Do not include the lentgh of the threaded shank.

  Measurement from Ground to Inside Top of Receiver Tube
GROUND TO INSIDE TOP OF RECEIVER HITCH
Measure from the ground directly below the receiver to the inside top of the receiver tube. This is where the top of the shank will sit.

  Coupler Height above ground with trailer parallel to ground
COUPLER HEIGHT ABOVE GROUND
Level the trailer. Measure to the frame on the front & back of the trailer and use the tongue jack to raise or lower it until the measurements at both ends are the same, and the trailer is sitting parallel to the ground.

Measure from the ground to the top of the socket where the hitch ball fits into the coupler.

  Receiver Size

RECEIVER SIZE
Most receiver hitches on tow vehicles large enough to tow a trailer that would require weight distribution are 2" x 2" square.

Some newer model Heavy Duty pickup trucks are equipped with a 2½" x 2½" square receiver hitch.

Some smaller tow vehicles, like mini-vans, crossovers, or very small SUVs have receiver hitches that are smaller than 2" x 2". Equal-i-zer adjustable shanks will not fit these receiver hitches.

  Do you need an extended shank length?

EXTENDED SHANK LENGTH
An extended shank gives you more room behind the tow vehicle to make room for tailgate mounted spare tires, and other things that can get in the way and damage your trailer in a tight turn.

Most people do not need an extended shank, and using the shortest shank possible is the safest option.

If you have questions or concerns about your particular tow vehicle, talk to your dealer, or call our customer service staff for help.

  Is this shank for a 4K Equal-i-zer hitch?
DO YOU HAVE A 4K EQUAL-I-ZER HITCH?
The 4K model (400 lbs. max tongue wt. / 4,000 lbs. max trailer wt.) hitch uses a smaller, lighter weight shank than the other (6K-14K) Equal-i-zer models. They are not interchangeable.

If you have, or are considering a 4K Equal-i-zer hitch, you must use a 4K shank.

In high gusty winds (25-35 mph) there never is a moment when we feel the least concern. Control is absolute and positive at all times. Your hitch is great!
