What Is the High Hump Transmission Cover?

Also called the transmission tunnel or transmission hump, this metal floor panel covers the area where the transmission and drivetrain components pass through the cab floor. The raised "high hump" profile is specific to 4WD and big block equipped trucks, providing the extra vertical clearance needed for the higher-mounted transmission and shifter assembly.

Product Highlights:

• ✅ Correct for 4WD, 4x4, and big block applications — provides necessary transmission-to-floor clearance
• ✅ Dimensions: 24" L x 18" W x 7¾" H — full-size reproduction of the original high hump profile
• ✅ Reproduction quality — correct shape and size for accurate fitment in the cab floor opening
• ✅ Replaces damaged, rusted, or modified originals — restores both appearance and structural integrity
• ✅ Some fitting and trimming may be required for a perfect installation
