The MACH-1 quick change kit includes: 1 hub and 2 sprockets of your choice.

Hubs and sprokets can be purchased seperatly but a kit will be offered which will be 1- hub and 2 sprockets of your choice.

Here are a few interesting facts:

These sprockets will be hard anodized to increase life and wear(just like the high end mx bike sprockets) , should last much longer than normal aluminum sprockets.

The hub will be made from 7075 aluminum instead of 6061 , yes it bumped our production cost up but the added STRENGTH and DURABILITY were our first priority.

The hub will also get the hard anodized treatment .

Designed by MACH-1, they are made in America by ZTR .

Here is a pic of one (cosmetically unfinished prototype) installed for testing .

The ZTR Products Quick Change Hub and Sprocket is the newest addition to our product line. The development of this New Quick Change Hub and Sprocket Assembly is due to a much needed time savings in the mini quad industry. It is designed to fit the DRR and Apex mini quads. The patent pending design has proven to be a huge time saver for any racer adjusting their quad due to the ever changing track conditions.

The hub and sprocket are both HARD black anodized which increases the surface hardness of the 7075 Aluminum and in turn produces a longer lasting product. The racer as well as the avid rider will benefit from the major improvements that the New Quick Change Hub and Sprocket bring.
