1999-2007 Chevrolet Silverado / GMC Sierra 1500 Classic Welded Underbed C-Notch
This Trekline Motorsports welded underbed C-notch is engineered to create additional rear axle-to-frame clearance on lowered trucks while keeping the notch structure tucked under the bed. It is intended for serious rear drops and axle-flip combinations where factory frame clearance becomes limited.
