GMC Sierra Denali 2500 HD Splash Shield Kit - Lower - Wehrli - Duramax 6.6L - Brizzle Blue - `11-`19. A heavy-gauge aluminum lower cover that replaces the fragile factory plastic on 2011–2019 GM HD trucks to protect the lower engine bay and cooling stack.

Made in the USA by Wehrli Custom Fab, this Brizzle Blue powder-coated shield adds strength and broader front coverage versus the OEM panel. It installs with basic hand tools, uses factory mounting points, includes new flanged hardware, and features built-in standoffs plus brackets to properly support the lower radiator hose. Confirmed fitment on stock-height and leveled trucks; if your truck has a suspension lift, please contact us to confirm compatibility. Not a skid plate.
