The Wehrli brake reservoir cover in Brizzle Blue is a powder-coated fabricated aluminum overlay that fits over the stock plastic master cylinder reservoir for 2001–2019 GM 2500/3500 Duramax trucks. It uses OEM mounting points and installs in minutes with basic hand tools, providing a finished engine-bay appearance. Pairing it with a matching billet cap completes the customized look.
