This kit upgrades the white tracks on the HQ Studio Frame to aluminum HQ Precision-Glide Tracks. It includes 8-wheel carriage assembly and adaptor boards for the HQ Sixteen. For more information on this upgrade visit the upgrade information page and look for information on upgrades to your existing machine.
If you have the HQ Pro-Stitcher you will also need to upgrade your carriage. There are three different configurations possible. Please contact us if you have any questions.
