The Wehrli billet aluminum brake reservoir cap in clear anodized finish is a direct OEM replacement for 1999–2025 GM 1500/2500/3500 trucks. CNC-machined in the USA from billet aluminum, it reuses the OEM diaphragm and installs in seconds. Offered as a complete cap rather than a cover, it provides a machined, anodized finish choice and straightforward OEM-style fitment.
