This Wehrli gloss white master cylinder cover fits 2001–2019 GM 2500/3500 Duramax trucks (LB7/LLY/LBZ/LMM/LML/L5P) and replaces the OEM plastic reservoir cover with a fabricated aluminum unit. TIG-welded and powder coated, it uses factory mounting points and basic hand tools for a quick install and can be combined with a WCFab billet reservoir cap to complete the look.
