Frequently Asked Questions
This assembly is designed to be cut from 4130 chromoly and TIG welded. The DXF files give you the plate geometry, so you can run them on a plasma, laser, or waterjet, but the design is built around chromoly so plan your material accordingly.
Some of the plates are made to be press bent, not just cut flat. You'll want access to a press brake along with your cutting setup, and since it's a complex assembly, a rep from DIY Off Road will reach out after purchase to walk you through the options.
Honestly, professional experience is a must on this one — it's a complete Y-frame assembly in chromoly that needs to be TIG welded. Because of the complexity, someone from DIY Off Road will reach out personally after you buy to make sure you've got what you need.
These are digital — soon as your payment goes through you get a download link for the DXF cut files. Nothing physical ships.

Yeah — if you don't have your own CNC plasma, laser, or waterjet, shoot us an email and we'll send over a few shops that can cut (and press/bend) the parts so you can weld them up.
Soon as your payment goes through you get a download link for the DXF cut files. You (or a shop) cut them from steel on a plasma, laser, or waterjet, bend whatever needs it, then weld them into your build. Nothing physical ships.
Yep — these are cut files for DIY and pro fabrication. A lot of the parts are "plasma table friendly" (flat plate, no bends) to make cutting and assembly easier, but you'll need to cut and weld them in yourself, or have a shop handle it.
