GMC Sierra Denali 3500 HD Engine Splash Shield - Lower - Wehrli - Heavy Gauge Aluminum - WCFab Grey - 2011–2019. A durable aluminum replacement for the vulnerable factory lower engine cover, built to help protect the underside and cooling stack.

Made in the USA from heavy gauge aluminum, this lower front cover offers added strength and increased coverage compared to OEM plastic while keeping service access straightforward. Finished in WCFab Grey powder coat, it installs with basic hand tools using factory mounting points, includes high-quality flanged hardware, integrates lower radiator hose support brackets, and uses built-in standoffs at the frame. 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—designed to guard against road debris, not heavy trail impacts. Compatible with gas and diesel 2500/3500 HD models.
