Premium Bed Floor Assembly for OE Wheelhouses 19882000 Chevy GMC C/K Shortbed Fleetside Pickup
The Premium Bed Floor Assembly for OE Wheelhouses is a complete OE-style sheet metal replacement designed for 19882000 Chevrolet and GMC C/K Shortbed Fleetside pickup trucks, including C1500, C2500, K1500, K2500 (19881998) and C3500, K3500 (19882000) models such as Silverado and Sierra. Engineered specifically for trucks retaining original-equipment wheelhouses, this premium bed floor assembly restores factory-correct structure, strength, and appearance to GMT-400 OBS classic trucks.
Manufactured on all-new AMD tooling, this premium restoration part replicates original GM contours, bed floor ribbing, cross sill placement, and mounting geometry. The stamping is designed to mirror OE specifications, ensuring proper alignment with factory bed sides and OE wheelhouses. Accurate bed floor geometry is critical on OBS trucks, directly affecting tailgate alignment, bed-to-cab fit, and overall truck presentation.
Constructed from heavy-gauge automotive steel, the assembly arrives finished with a protective EDP coating to resist corrosion during storage and preparation. Designed as a direct OE-style replacement, it integrates with original bed components while maintaining the correct factory look expected during full restorations and truck rebuild projects.
Unlike partial repair panels, this complete premium bed floor assembly replaces compromised sheet metal across the entire bed surface, restoring structural integrity from the front bed panel to the tailgate opening. It is ideal for classic truck restoration projects where durability, correct fitment, and authentic sheet metal geometry are essential.
This bed floor assembly replaces original GM part numbers 15646301 and 15611241, delivering an accurate solution for OBS Silverado and Sierra trucks that require full bed floor replacement.
Auto Metal Direct continues its commitment to premium-quality classic truck sheet metal with this OE-style bed floor assembly, providing the strength and precision OBS truck owners demand.
