Description
Bed Wheelhouse 5″ Wider 19882000 Chevy GMC C/K Fleetside Pickup
The Bed Wheelhouse 5-Inch Wider is an AMD-exclusive sheet metal upgrade engineered for 19882000 Chevrolet and GMC C/K Fleetside pickup trucks, including C1500, C2500, K1500, K2500 (19881998) and C3500, K3500 (19882000) models such as Silverado and Sierra. Designed to fit both short bed and long bed Fleetside configurations, this wider wheel tub provides additional clearance for modern wheel and tire setups while maintaining OE-style integration with the factory bed structure.
Unlike producing multiple wheelhouse sizes, AMD developed these wider tubs as a dual-purpose design, giving builders flexibility without compromising fitment. When installed with compatible suspension configurations, these wheelhouses allow up to a 3-inch wider tire footprint without requiring additional modification. For performance builds utilizing a Detroit Speed 4-link system or equivalent rear suspension upgrade, the design supports up to 5 inches of additional tire clearanceall without further customization to the tub itself.
Manufactured from heavy-gauge automotive steel on all-new AMD tooling, these wheelhouses replicate the original OBS contours and mounting geometry while expanding inward for increased clearance. The stamping maintains proper ribbing, structural integrity, and factory-style appearance inside the bed. Each wheelhouse arrives in a protective EDP coating, helping guard against corrosion during storage and preparation.
These wider wheel tubs are designed to integrate seamlessly with AMDs corresponding widened bed floor assembly, providing a complete performance-oriented solution for OBS truck restoration and custom builds. The result is a clean, factory-style installation with enhanced wheel clearance capability for enthusiasts who want both authenticity and modern performance fitment.
Auto Metal Direct continues expanding its GMT-400 OBS platform with precision-engineered sheet metal that supports classic truck restoration and high-performance applications alike.
