NOTE: This track upgrade WILL NOT work with the HQ Studio Frame for HQ Avante – First Generation (Curved Leg Frame). 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 Avanté. If you have the HQ Pro-Stitcher you will also need to upgrade your carriage. There are three different configurations possible.
