Wehrli LLY / LBZ / LMM Duramax Turbo Compressor Inlet Billet Steel Flange

If you're fabricating a custom turbo inlet or air intake setup for your LLY, LBZ, or LMM Duramax, this billet steel compressor inlet flange from Wehrli Custom Fabrication is what you need. It's designed to mate with the factory Garrett VGT turbocharger found on these trucks, giving you a solid starting point for your custom build.

This flange is CNC machined from solid billet steel right here in the USA, ensuring a well-built part that’s ready for welding. It's set up to work with either the stock GM worm gear style clamp or Wehrli's own upgraded stainless steel t-bolt clamp, which you can pick up separately. Just remember, the O-ring seal that sits at the turbo face is also sold on its own, so be sure to grab that too if you need it.
