GMC Sierra 3500 HD Splash Shield Kit - Lower - Wehrli - Sparkle Copper - '11-'19. Replace the vulnerable factory lower cover with a precision-built, Sparkle Copper aluminum shield for GM 2500/3500 HD trucks.

Engineered by Wehrli Custom Fab, this lower panel adds strength and clean coverage ahead of the cooling stack while keeping service access straightforward. It installs to OEM points with basic tools, includes new flanged hardware, built-in standoffs, and brackets that support the lower radiator hose. Compatible with gas and diesel models. Not a skid plate—designed to outperform the stock plastic panel, not absorb heavy trail impacts. Confirmed fitment on stock-height and leveled trucks; lifted setups should verify clearance before ordering. Made in the USA.
