GMC Sierra 3500 HD Engine Splash Shield by Wehrli – Cat Yellow (2001–2010). A heavy-gauge aluminum replacement for the fragile factory plastic, protecting the lower engine bay and cooling stack.

Made in the USA, this lower front cover adds strength and coverage while keeping service straightforward. It installs with basic tools using OEM mounting points, includes flanged hardware, and integrates brackets to support the lower radiator hose. Durable Cat Yellow powder coat. Not a skid plate; improved over stock but not for hard impacts. Confirmed for stock and leveled trucks; lifted setups should verify compatibility. Fits gas or diesel HD models.
