Cutting & Welding Snowmobile Rails | 155 to 144 Watercross Build

In this video, we cut and weld snowmobile rails to convert them from a 155 down to a 144 for a Watercross build. This setup is all about reducing drag, tightening up the chassis, and getting the sled dialed for racing on water. We walk through the cutting, fixturing, and welding process, along with why a 144 makes more sense for Watercross compared to a longer track. This is a real garage build — no shortcuts, just getting it done and making it work. If you’re into snowmobile fabrication, Watercross racing, custom sled builds, or learning how to modify parts instead of buying new ones, this one’s for you.
