This is the Kit with all the options.


The low-profile design reduces interference and friction from the tire during the half on phase, and the rake angle of the lever clears all of the commonly used “drop center tools.” The whole design makes the tire change flow smoothly, avoiding the snags that can turn the task into a chore.

This works with many types of tire changer as long as they have a 2" diameter Post Cap like the Harbor Freight tire changer

The kit replaces the rim clamps of the HF motorcycle tire changer with a spindle and pads with a pin that prevents the wheel from rotating

The 3/4”-20mm spindle will fit through most motorcycle bearings (unlike the Harbor Freight spindle which is 1” and requires the removal of your bearings to use.

Most motorcycle bearings will fit over the 3/4”-20mm spindle with less than an 1/8”of play, which is ideal.

  • Should you have one of the bikes with larger centers in your bearings, please let me know the size and I will make you a custom spindle.

This kit includes the 1/2”-13mm spindle for use with motorcycle rim which have a small hole in the center (like, for example, the BMW K 1200 RS rear wheel which is a single-sided swinging arm wheel with a lug nut going through the center hole), the 1/2”-13mm spindle will fit through it. However, this requires the Harbor Freight overhead arm to be lowered into position and the Harbor Freight vertical 1” spindle to be placed over the top of the 1/2”-13mm spindle using the provide bushing that makes it a tight fit.

The Unlimited Duckhead adapter upgrades the Harbor Freight manual tire changers into duckhead units that not only make the process a lot easier, but also enable you to safely work on alloy rims without damage by eliminating contact with the face of the rim.

Aluminum Centering Cones that replace the centering "spider" that come with the tire changer are available on this site.

The same Duckhead Arm is used in the motorcycle changer.

The kit comes with a tire lever that works perfectly on the duckhead and an extra hand.

The Unlimited Duckhead is nylon and only touches the underside of the lip and prevents any contact from the lever with the rim.

This works with many types of tire changers, as long as they have a 2" diameter post cap like the Harbor Freight tire changer.

It is available in Red, Yellow or Black. Other colors may be available on request.
