Description
Essential Structural Component. The Bed Cross Sill; Mid serves as a critical support between the wheel tubs in the pickup bed floor. It provides structural rigidity and stability, helping to maintain the bed's shape and integrity under load. This cross sill is designed for use in trucks with 5.5' and 6' beds, where it helps distribute weight and prevent bed floor flexing.
Construction and Appearance. Manufactured with durable materials, this mid cross sill offers reliable strength while maintaining a lightweight profile at 6.4 pounds. It is constructed to precise dimensions of 49" by 2 3/4" by 3 3/4", ensuring a perfect fit between the wheel tubs. The finish is designed for durability and resistance to corrosion and wear, complementing the truck's bed structure.
Installation. Installation involves mounting the cross sill in the designated position between the wheel tubs within the truck bed. The process is moderately straightforward but may require drilling, depending on the vehicle’s existing bed configuration.
Application. Specifically designed to fit 99-06 Sierra 1500 Fleetside.
