You dressed up the engine bay and the yellowed plastic brake reservoir is still sitting there. The Wehrli Brake Master Cylinder Reservoir Cover (Manufacturer Part # WCF100209) is a TIG welded fabricated aluminum cover that fits over the OEM plastic reservoir on your 2006-2026 Ram 2500/3500 5.9L and 6.7L Cummins, powder coated to match the rest of your build. It uses the factory mounting points and goes on in minutes.
Why Choose the Wehrli Brake Master Cylinder Reservoir Cover?
- Covers the part you cannot replace – the reservoir itself has to stay plastic, so Wehrli covers it instead of asking you to live with it.
- TIG welded fabricated aluminum – not a stamped or bent panel, welded and finished properly.
- Factory mounting points and hardware – nothing drilled, nothing modified.
- Minutes with basic hand tools – one of the fastest visual wins on the truck.
- Matches the rest of the build – same powder coat range as Wehrli's coolant tanks, intake kits and coolant pipes.
- Twenty model years on one part number – 2006 through 2026, 5.9L and 6.7L alike.
- Made in the USA.

Notes
- ⚠ 2007.5-2009 trucks — check next to your master cylinder before ordering. Some of these have a large electrical connector bulkhead beside the master cylinder that interferes with the cover. It has to be unbolted and relocated, supported by the harness on the firewall. Not difficult, but it is extra work you should know about first.
- Lead time varies by color. WCFab Red, WCFab Grey, Illusion Purple, Bengal Red, Candy Teal, Gloss White and Gloss Black are stocked and ship in 3-5 business days. All other colors are made to order on a 10-15 business day lead time.
- Pair it with a WCFab billet aluminum brake reservoir cap for the finished look.
