LEER Camper Shells for the GMC Sierra

The Sierra follows the same generational pattern as its Silverado twin — with one wrinkle: on current-generation trucks, fitment can vary by cab and tailgate configuration (Multi-Pro vs. standard). The table below shows the Silverado-pattern baseline; we confirm your exact configuration on every quote.
