Good luck finding info or help on this. I bought a used set of xt lightfoot tracks for my razor and have been unable to find anything on mounting for the razor. Mattracks will only give you an installation guide if you buy a new install kit. I called them and they told me I have a mounting kit for a grizzly, but the install guide I found for a ranger looks like the same kit that I have. I just need the rear frame mounts. Anyway, I have an install guide for a ranger, but the file is too big to upload on this post. If you know how I could send it to you, let me know. The rear torque arm bracket mounts to the box frame. My guess is the front probably mounts the same for the Razor and the Ranger, but then again, I could be wrong. I'm just trying to muddle my way through this too. The only issue could be the extended A arms on the razor S. I'm going to rough fit mine again, at some point, and try to figure it out. Last resort is to buy another install kit. Have a great day,
