GMC Sierra 3500 HD Splash Shield Kit - Lower - Wehrli - Duramax 6.6L - Brizzle Blue - 2011–2019. This heavy-gauge aluminum lower cover replaces the fragile factory plastic piece and adds solid coverage for the lower engine bay and cooling stack.

Built for direct bolt-on fitment, it uses OEM mounting points, includes new flanged hardware, and incorporates brackets for proper lower radiator hose support with built-in frame standoffs. The Brizzle Blue powder coat provides a clean, durable finish and increased coverage versus the OEM panel while keeping service access straightforward. Made in the USA. Not a skid plate—offers improved protection over plastic but is not intended for heavy impacts or trail obstacles. Confirmed on stock-height and leveled 2011–2019 GM 2500/3500 HD (gas or diesel, including Duramax 6.6L); for lifted trucks, please contact us before ordering.
