**All wheels in this listing are all with cage mounts.**
These are the Genuine Raptor Mod Wheels that are safe, reliable, sturdy, and silent. They are made from resilient materials and are designed specifically to meet your gliders needs. 
 
The size of these wheels are 12" in diameter... so just add 1 inch to the track size, and that is the width of your wheel. Example the raptor mod with a stock 5" track would be 6" wide (to fit it in your cage the door or opening must be 12" x 6" all track widths will very by + or - 1/4")
 
Best of all, Raptor Wheels are built right here in the USA
