This Wehrli Custom Fab aluminum master cylinder cover cleans up the engine bay of 2001–2019 GM 2500/3500 Duramax trucks by fitting over the OEM plastic brake reservoir. Fabricated from TIG‑welded aluminum and custom two‑stage powder coated in Illusion Purple, it uses OEM mounting points and hardware for straightforward installation with basic hand tools. Pairing with a billet reservoir cap completes the appearance upgrade.
